• Hard crash when using bluetooth headset on MacBook Pro and Lion 10.7.2

  - by jtalarico

  I recently picked up a bluetooth headset (Motorola S10-HD) and started using it with my MacBook Pro (17" purchased new in 2010) running Lion 10.7.2. Here's what works - stereo audio: iTunes Spotify Pandora (via browser) games (e.g. Minecraft, which is a Java app) audio from YouTube Plex, VLC, other video players Here's what doesn't work well - stereo audio fails and the headset seems to go into mono (i.e. tinny-as-hell) mode: Google Hangout Skype GoTo Meeting Here's what's just downright catastrophic. If I'm listening to stereo audio and then decide to jump into a Skype call (Google Hangout, or GoTo Meeting), bluetooth often crashes and I can only get things working again by shutting down the device, disabling bluetooth, and getting things back up and running again. But the audio is still horrible, and MUCH better using just a simple set of iPhone earbuds and mic. About 80% of the time during such a call, bluetooth crashes. And about 90% of the time, after the call ends, Skype is shut down, or I try to switch back to playing stereo audio, I get a hard crash!! The gray screen of death descends and I'm told I need to restart my machine. In one such instance, even after a reboot, I could not enable bluetooth again ("Turn Bluetooth On" was grayed out in taskbar). Is this just a weak implementation of bluetooth by Apple, or is this a hardware issue? I've seen others posting similar issues even on the Apple support site indicating that bluetooth headsets are failing left and right, but I haven't seen anyone mention hard crashes.

• Network structure --> Server 2k8r2 <--> Livebox <--> Router <--> Other PCs

  - by Yusuf

  I have a Livebox connection to the Internet and I have set up my network as follows: - Livebox <--> Win2k8R2 Server - Livebox <--> Netgear N150 Router - Router <--> Other PCs Therefore, in my LAN, - the Livebox has IP address 192.168.1.1, - the Router 192.168.1.12 (when accessed from the Livebox or the server), - the Router 10.0.0.1 (when accessed from the PCs connected to the Router), - the server 192.168.1.2, - the PCs 10.0.0.x I was using a previous configuration, which was as follows: - Livebox <--> Netgear N150 Router - Router <--> Win2k8R2 Server - Router <--> Other PCs Everything was simple, and I just had to forward all ports for incoming connection on the Livebox to the Router, and then forward the specific ports to the Server as needed (it must be however noted that any server I use is found on the Win2k8R2 server itself). In this previous configuration, the IP addresses were as follows: - Livebox 192.168.1.1 - Router 192.168.1.12 (when seen from Livebox) - Router 10.0.0.1 (when seen from server & PCs connected to it) - Server 10.0.0.2 - PCs 10.0.0.x So now of course, my port-forwarding does not work anymore since the server is not connected (directly) to the Router. What I would like to know is how do I configure the Livebox and Router to still have the features like before? From what I understand of networks (which is very limited, btw), I see these options: Make the router assign IPs like 192.168.1.x (but then I want the forwarding to be done from the router itself, is it possible?) The forwarding on the router to the server uses IP address 10.0.0.2. I could change it to 192.168.1.2 (Is that even possible, does it work?) Forward all ports from the Livebox itself to the server, and then manage them there (Is software-based port-forwarding as secure as hardware-based?)

• Transfer disk contents *without* cloning tools

  - by Chris Cummins

  Is it possible to "clone" a disk which contains programs by performing a copy of all the disk contents (preserving file attributes) from source to destination disk, and unplugging the source disk and changing the drive letter of the destination disk to match that of the source? Context I have a two disk Windows 8 system with a system drive and a data drive. Recently, the data drive developed a number of bad sectors leading to IO errors. I have been sent a replacement drive so I simply need to clone the contents of this data drive onto the replacement. The drive contents include documents & media, user folders (My Documents and related), and some programs (games etc). Problem The problem is that the bad sectors on the source disk causes most disk cloning tools to fail with read errors. Attempted approaches include: Disk clone from live boot environment with Acronis True Image. Fails due to read errors. Disk clone from live boot environment with Clonezilla. Fails due to read errors. Disk clone using Roadkil's Unstoppable Copier. Fails due to hardware timeouts in the HDD (application hangs indefinitely). A straightforward copy from source to destination disk using FreeFileSync (preserving file attributes and metadata). This succeeds. So at the moment I have a replacement disk which contains all of the data from the original disk. Now all I need to is somehow get Windows to replace all references to the old disk to the new one. Is this possible by simply swapping the assigned drive letters? Any help would be greatly appreciated, thanks!

• Vista won't boot. BSOD: Page fault in nonpaged area

  - by user31576

  Here's the story: I let Windows Update do the updates it wanted to do, then rebooted the computer. The updating process was taking time so I went away. When I came back, my computer was rebooting. It got as far as the Windows logo with the laoding bar. BSOD'd. Rebooted. And I'm stuck in this loop ever since. Looked up on the net, the "Page fault in nonpaged area" seems to be linked to faulty RAM or drivers. So I ran a memory test, it found no error. When I try in safe mode (with promt) I can see a list of drivers being loaded, then I get the same BSOD. I tried to repair using the Vista DVD, it says "nothing to repair". I tried to restore to a previous state, it says "no restore point found". So, my guess is, it's got something to do with the drivers. How can I identify the one causing the BSOD? If you have any other leads, What can I do? By the way, I'm writing from this very computer, running a linux distro I installed after the BSOD loop started. So i guess it's not an hardware issue. I have backed up important data, and will format and reinstall Windows if I must. But I'd like to avoid that. Thanks in advance for any help you can give me.

• Disable or remove filter driver for single HID device

  - by snoopen

  Running Windows XP in a corporate setting here. I have an issue where a filter driver is interfering with the functionality of different USB HIDs. For example graphics tablets do not respond while the filter driver is in place. I've also had the issue with foot pedals used with transcription software. My question is really two fold: A) what makes Windows use a filter driver on one HID but not another? B) when a filter driver is causing conflicts how can I disable it on the affected devices? Background I've previously narrowed down the issue to the filter driver by uninstalling the software (Funk Proxy Host) responsible for the filter driver. The software is a type of RDP we use here at work. (I might have even booted into safe mode and renamed the file, I forget). I believe the filter driver is present to disable or modify the use of the local keyboard and mouse while admin staff are assisting users. Either way I don't have the authority to just go uninstalling this software. As far as I can tell the software versions are the same, however I'm not sure if the device driver definitions are all the same as I don't know where these things would be located. To check for the presence of the filter driver I locate the hardware device in Device Manager, click Properties Driver tab Driver Details.... It shows up as ph32ihid.sys. Even though all machines are meant to have the same SOE and do have Funk Proxy Host installed I don't always have issues with the same HIDs. A few machines here the foot pedals without any issues. I've not had any machines work with the graphics tablet without uninstalling Funk software. Driver details I've just read up a bit more about filter drivers and found the drivers description in the registry under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProxyHostHIDFilter" There it's called "Kernel-mode HID filter driver for the Proxy Host". Presumably I could also disable it here but that would be system wide which is probably not desirable?

• Windows XP hanging on login screen

  - by Nathan W

  I have been given two Eee PC 100HA to manage for some people, they are both running the same hardware and XP home but one is having some strange problems with logging on. The main problem is that it hangs at the login screen for ages and sometimes never gets to the desktop. The strange thing is it only seems to do it after the computer has been cold started, but it won't do it if the computer has been restarted. I have made two logs of the start up with process monitor but every time the logger is attached the computer will log in fine. I have also set the computer to blue screen and create a crash dump when you press ctrl scroll twice but when I do it at the hung login it just sits at a black screen and I don't get a crash dump, I have turned off the auto system restart on failure option also. I can usually fix most computer start up and shutdown problems but this one has got me stuffed. Has anyone had the same problems before, or can recommend something that I can try? Cheers.

• VT-x not enabled on 2010 Mac Pro

  - by BlindingDawn

  To start I had a Hackintosh as per the instructions from Lifehacker.com before and moved everything to a new 2010 8 Core Mac Pro. I opted for a restore from the time machine backup rather than using the migration assistance. I believe this may have caused more problems but one in particular is the lack of VT-x support. When I checked Parallels Desktop under "Host Hardware" information, I get the following that shows that VT-x isn't enabled. <Cpu dyn_lists=""> <Number>16</Number> <Model>Intel(R) Xeon(R) CPU E5620 @ 2.40GHz</Model> <Mode>1</Mode> <Speed>2400</Speed> <VtxEnabled>0</VtxEnabled> <VtxMode>1</VtxMode> 1) Does Parallels Desktop support using VT-x? 2) Does this setting show that my VT-x isn't enabled? 3) Is there a way of fixing it so that it is enabled? 4) Is there a way of using my Time Machine backup as if I'm doing a restore using migration assistance and just restore the files and settings?

• Where is my problem? The P6X58D Premium Mobo, Windows 7, or other?

  - by Dylan Yaga

  I was having problems with my USB devices for an hour last night, and I am unable to determine the root cause of the problem. The two symptoms are: At seemingly random times (not consistently spaced by time or caused by any detectable event) my USB devices become "detached". Windows will play the USB disconnect sound and then the reconnect sound. The devices disconnected and then reconnected. My USB Keyboard will "stick" on one key for several seconds before processing any other keystroke made. The mouse also does not respond to clicks. I do not lose mouse movement or USB device connectivity. And after a moment of this several beeps will be emitted from the speakers. Hardware Specs: GFX Card: EVGA GeForce GTX 470 Superclocked 1280MB DDR5 PCIe Motherboard: ASUS P6X58D Premium Intel X58 Socket LGA1366 MB Processor: Intel Core i7-920 2.66Ghz 8M LGA1366 CPU Memory: Corsair Dominator 6144MB PC12800 DDR3 Storage: Hitachi 1TB Serial ATA HD 1600MHz 7200/32MB/SATA-3G Cooling: Corsair Hydro H50 CPU Liquid Cooler Case: Corsair Obsidian 800D Full Tower Case Power Supply: Corsair HX1000W 1000W Modular Power Supply Steps I have taken to narrow down the problem: Restarted the computer. - No change Changed USB port the Hub was connected to on the CPU. - No change Removed all devices from USB Hub and connected directly to CPU. - No change Used a different USB keyboard both in USB Hub and directly to CPU. - No change Disconnected and reconnected all cables. - No change Disassembled the Tower and determined if the USB headers were firmly connected. - No change Checked device manager for errors. Checked all USB devices. - Nothing flagged After an hour of frustration trying to narrow down the problem it appeared to disappear. But I am torn between it being a Mobo problem or an OS problem. Is there anything else I can do to narrow down the problem before a reformat and then eventually exchanging the Mobo?

• SQL Server performance on VSphere 4.0

  - by Charles

  We are having a performance issue that we cannot explain with our VMWare environment and I am hoping someone here may be able to help. We have a web application that uses a databases backend. We have an SQL 2005 Cluster setup on Windows 2003 R2 between a physical node and a virtual node. Both physical servers are identical 2950's with 2x Xeaon x5460 Quad Core CPUs and 64GB of memory, 16GB allocated to the OS. We are utilizing an iSCSI San for all cluster disks. The problem is this, when utilizing the application under a repeated stress testing that adds CPUs to the cluster nodes, the Physical node scales from 1 pCPU to 8 pCPUs, meaning we see continued performance increases. When testing the node running Vsphere, we have the expected 12% performance hit for being virtual but we still scale from 1 vCPU to 4 vCPUs like the physical but beyond this performance drops off, by the time we get to 8 vCPUs we are seeing performance numbers worse than at 4 vCPUs. Again, both nodes are configured identically in terms of hardware, Guest OS, SQL Configurations etc and there is no traffic other than the testing on the system. There are no other VMs on the virtual server so there should be no competition for resources. We have contacted VMWare for help but they have not really been any suggesting things like setting SQL Processor Affinity which, while being helpful would have the same net effect on each box and should not change our results in the least. We have looked at all of VMWare's SQL Tuning guides with regards to VSphere with no benefit, please help!

• How do I restore to a delta file (disk) on Vmware ESXi

  - by Oscar

  Using VMware Server ESXi (freebie version) I have a Virtual Machine (win 2k3 r2 server). When I first provisioned it I took a snapshot of it. I recently tried to clone the primary drive using my standard hardware-based method to grow a windows disk. (using knoppix, clone drive to a new drive, make it bootable, then I intended to extend the partition via diskpart from within windows). This process failed; I tried setting the cloned drive (via the vmware gui) to replace the original drive, boot and be done. This didn't work out so well. The machine never booted. I checked the boot order, the disk location and all the basics I usually do. As a failsafe, I then tried changing all the settings back so the machine would boot to the original drive and I could figure out (as I eventually did) a better way of growing the disk. However when I powered on the machine with the original drive, it reverted back to that initial snapshot I created; It lost all the changes since. I looked in the file system and found a few files, I think the keyfile here is one named "delta" and I'm assuming that's the disk I want, but I can't find a way to have the Virtual Machine actually use that drive/file. It isn't available to add when I go to add an existing drive. Do I need to somehow commit that delta to the original drive and then boot from it again? Can you point me in the right direction? I've since discovered the proper way of growing drives using "vmkfstools" but I need to get back to the original state of the machine to try this out. Any help would be greatly appreciated.

• Wired to wireless bridge in Linux

  - by adrianmcmenamin

  I am attempting to set up my Raspberry Pi as a bridge (but I think this is not a question specific to the hardware) - using Debian wheezy. I have a hostapd.conf: (some details changed for security)... interface=wlan0 bridge=br0 driver=nl80211 auth_algs=1 macaddr_acl=0 ignore_broadcast_ssid=0 logger_syslog=-1 logger_syslog_level=0 hw_mode=g ssid=MY_SSID channel=11 wep_default_key=0 wep_key0=MY_KEY wpa=0 (yes, I know WEP is no good) And this in /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp auto br0 iface br0 inet dhcp bridge-ports eth0 wlan0 Everything seems to come up ok, but I cannot associate with the bridged wireless connection - even though the flashing lights on the USB stick suggest packets are being exchanged. I have read somewhere that not all cards/devices will run in hostap mode - they won't pass packets in one direction: is that right? (The info was a bit old)- this my card: [ 3.663245] usb 1-1.3.1: new high-speed USB device number 5 using dwc_otg [ 3.794187] usb 1-1.3.1: New USB device found, idVendor=0cf3, idProduct=9271 [ 3.804321] usb 1-1.3.1: New USB device strings: Mfr=16, Product=32, SerialNumber=48 [ 3.816994] usb 1-1.3.1: Product: USB2.0 WLAN [ 3.823790] usb 1-1.3.1: Manufacturer: ATHEROS [ 3.830645] usb 1-1.3.1: SerialNumber: 12345 So, what have I got wrong here?

• NTBackup (on WS2k3) fails to backup remote server (WS2k8R2) with " Error: is not a valid drive, or you do not have access."

  - by Mark A

  We run an NTBackup job on a Windows Server 2003 R2 SP2 with all updates (as of Q4-2011). It works well backing up two WS2k3 servers as well as the backup server itself. However, we have been unable to successfully back up our Windows Server 2008 R2 machine ("G5-01"). It often runs for about 2GB worth of backup and then dies out with one of the below error messages. It should be more like 20GB for the full server. We have tried using the admin share (C$), an explicitly shared drive share, UNC and mapped drives. The result is the same each time, the only thing that varies is the amount of stuff backed up before it chokes. We've also run NTBbackup from the UI interface, from the command line and as a scheduled task. We are backing up to 400/800GB tapes and they have plenty of space available on them (blank media). Error: \\G5-01\c is not a valid drive, or you do not have access. Error: \\G5-01\c$ is not a valid drive, or you do not have access. Error: Y: is not a valid drive, or you do not have access. Error: Could not access or create backup catalog files. Verify that you have full access to the working folder and there is disk space available. The job is run as Administrator and we have no problems logging onto the server and transferring files. The Event Log on the WS2k8 is not much help, as it has success audits for each login. All of the hardware involved (HP DL360 G3, HP LTO Ultrium 3, Adaptec 39320A) has the latest supported drivers. We've seemingly tried a bunch of different options but are wondering where to look next to resolve the backup issue. We've been super happy with our reliable schedule task for years but this one is stumping us!

• Computer freezing while watching Flash videos from net

  - by t3st

  I have a Windows 7 home basic, while watching videos from net (within 5 minutes) computer starts to freeze and shows 100 percent CPU usage. I first thought it's a browser issue but watching videos from different browsers also has the same issue. My system runs the latest Firefox browser and all my plugins (including Flash) is up-to-date. After this when I shutdown/restart the computer it will go to the login window with out any problem. From there when I tried to log in to any account, the system starts to freeze and again I have to start and run Windows in safe mode (which doesn't show any problem). I read it in an article to do these steps CMD->sfc/scannow chkdsk after that only my system works normally, even now I can't watch any videos on the net otherwise it starts freezing( I can watch downloaded videos in computer without a problem) and have to do the whole process once more (which takes a lot of time). while running sfc/scannow its showed results that some of the files are corrupted and it could not be repaired. Can this be the cause for freezing of my computer while running Flash videos? or is it a hardware related problem? What different steps do I have to take to correct those corrupt files? System restore works only some times.

• Switch to IPv6 and get rid of NAT? Are you kidding?

  - by Ernie

  So our ISP has set up IPv6 recently, and I've been studying what the transition should entail before jumping into the fray. I've noticed three very important issues: Our office NAT router (an old Linksys BEFSR41) does not support IPv6. Nor does any newer router, AFAICT. The book I'm reading about IPv6 tells me that it makes NAT "unnecessary" anyway. If we're supposed to just get rid of this router and plug everything directly to the Internet, I start to panic. There's no way in hell I'll put our billing database (With lots of credit card information!) on the internet for everyone to see. Even if I were to propose setting up Windows' firewall on it to allow only 6 addresses to have any access to it at all, I still break out in a cold sweat. I don't trust Windows, Windows' firewall, or the network at large enough to even be remotely comfortable with that. There's a few old hardware devices (ie, printers) that have absolutely no IPv6 capability at all. And likely a laundry list of security issues that date back to around 1998. And likely no way to actually patch them in any way. And no funding for new printers. I hear that IPv6 and IPSEC are supposed to make all this secure somehow, but without physically separated networks that make these devices invisible to the Internet, I really can't see how. I can likewise really see how any defences I create will be overrun in short order. I've been running servers on the Internet for years now and I'm quite familiar with the sort of things necessary to secure those, but putting something Private on the network like our billing database has always been completely out of the question. What should I be replacing NAT with, if we don't have physically separate networks?

• Configure linux machine as bridge/switch and end device

  - by leemes

  At my home, I have two desktop PCs in two rooms. The router / DSL modem is in one of these rooms. Now I want to configure a home server (having 2 LAN ports, running 24/7) in the corridor between the two rooms, using only one LAN cable at each door. This gives me the following physical configuration: (door) (door) .----/-/----. .-----/-/----------._ FritzBox | | | .----´´ DSL Router PC1 Server | PC2 As just said, the server has 2 network interfaces and is running Ubuntu. What I need now is a network configuration which enables both the server and PC1 to connect to the router. I think the server needs to serve as a bridge or switch. Currently, all computers are configured having static IP addresses. If I'm understanding it correctly, a bridge / switch doesn't have its own IP address, but as the server needs to be configured as an own end device, it needs to have one. My first question is, do I have to configure both interfaces separately, giving both the same static IP address? My next question is, how do I bridge the two physical networks into one? I have basic understanding (but am always confused again and again) of bridges and switches, but I don't know how to configure it in software. I only know that it's possible to do so :) The third question is: Is it possible to configure this in a way that network packets from/to PC1 to/from the router only go through hardware or only consume low CPU in the server? Can you help me? Thanks in advance!

• Why do I need a managed switch and which one should I buy?

  - by ascanio1

  I bought a 2nd router and I want both routers to have direct WAN access to the modem. One of the 2 routers directs VOIP traffic to a telephone line port. This VOIP service is provided by the cable carrier which also leases the modem & the router. The cable company technician told me that this VOIP line uses IPv6 addressing and therefore I must employ an IPv6 capable/compliant Giga Hub/Switch or my telephone line won't work anymore. Pls advise me (brand/model) an IPv6 compliant, 2 port, switch to purchase. Pls educate me: By reading this forum I thought that hubs broadcast traffic to all ports, regardless of which input/output is being used and so, theoretically, they have nothing to do with IP. Correct? Same story for unmanaged switches, where the only difference is that these latter devices route traffic only to those ports which are detected to be in use. Correct? I also understood that unmanaged switches route traffic simply by detecting hardware use and not by selecting specific IP traffic. Correct? Finally, there are managed switches which DO select traffic based on IP and, therefore, only these managed switches are involved with IPv6... Why would my cable company explicitly tell me, over and over, that I must use an IPv6 compliant switch? Why would they need a managed switch instead of an unmanaged one? Thanks in advance for helping me understand!

• GUI interfaces to ATI card behave weirdly out of the box and after updates.

  - by jdk

  My Lenovo W500 came with an ATI Mobility FireGL V5700 and both the Catalyst control center software and Vista display manager display four monitors. What's really annoying is the behaviour. My two active displays (laptop display + my external monitor) are always #s 3 and 4 respectively which doesn't make sense. This is out of the box. Additionally dragging & dropping is jumpy and displays #1 and 2 (always inactive because they don't exist to the software) are often preventing me from dragging #3 and 4 to the rightmost side. They also auto-snap to weird positions and certain sensible positions like position one directly over top of the other are not possible. The exact same annoyances are present when using the Windows Display manager too. In other words the interface is crap and I'm looking for a fix that's not wishing I had gone with nVidia instead. I've updated drivers, and Catalyst control centre. Have latest Windows and AMD/ATI updates. Any thoughts?

• All network devices freezing when Airport Extreme Base Station is connected. Any ideas?

  - by Jon

  I've been troubleshooting this issue for a while, and through a series of events have it narrowed down to my airport extreme base station. I like this router, since I'm able to connect to IPV6 sites without any insane configuration (my alternate router is too old and doesn't support v6). My question is: Has anyone else had this issue, if so how is it resolved? If not, can you recommend a good IPv6 router? Here is how I came to the conclusion that it is the router: Devices: XBOX 360, HTC Incredible, Home-Built machine running FreeBSD, Home-Built machine running Ubuntu 10.04. 1.) Noticed freezing on Ubuntu Box. 2.) Noticed freezing on XBOX360 3.) Noticed freezing on HTC Incredible (only when connected to my network wirelessly). The above all happened at random times throughout the past few weeks. Over the last few days, I was playing XBOX and noticed that the XBOX and Ubuntu machines both froze. I picked up my phone, and it was also frozen. I reset all devices, power-cycled my router, and all was fine again. About two hours later, it happened again (I was playing Forza III, the XBOX froze; I went to the Ubuntu box and it was frozen; unfortunately, the HTC phone was not connected wirelessly, and the FreeBSD box was turned off). I can't even begin to imaging what a router could be doing to freeze devices with such differing hardware/software/OS, and I feel absurd for coming to this conclusion, but I have nothing else. I hooked up my archaic Netgear router, and have had no problems since. :(

• Windows Server 2012 Can't Print

  - by Chris

  I know this may sound incredibly stupid and there is probably an easy solution but I can't seem to find it. Friends of mine recently upgraded their server for their small business from the POS old one. New hardware and a change from Windows Server 2003 to Windows Server 2012. I've got everything they need transfered over and running except for printing. They need to be able to print to printers in the vans their technicians use from the server via remote desktop. In other words the use a laptop to remote desktop into the server and need to print invoices out from the remote server to printers attached locally via usb. On the old server they just installed the identical driver and that was it, they could print as needed. On this server no matter what we seem to do we can't get it to print remotely, and in the process we also discovered that the server can't even print to the network printer. It sees the printer on it's network and it sees (through redirect) the printers in the vans but when you hit print it claims it did and nothing happens. There isn't an issue with the printers themselves as every other device we have can print to them without issues. Is there some setting that is inhibiting the server from printing? Is there something I need to install (print server?) to add the functionality? Thanks in advance for helping me out here

I can connect to a website on the server from an external computer, but after a certain amount of time (mins to hours), I can no longer connect. All I have to do to re-enable connectivity is connect to the server via SSH from a computer INSIDE the network. I don't have to actually login, I just have to establish a connection. I can then access the website externally again. I did some googling and it seems some of verizon's equipment had an ARP bug where the ARP entries would expire after a certain time period, but those issues all seem to be from back in 2009 - 2010. I know the switch has an 'auto learning Mac address' feature, but I'm not sure if that could be the problem or not. Does anyone have any ideas or advice on how I can troubleshoot this? Thanks!

• Looking for an application that scrolls or pans netbook screens running Windows

  - by therobyouknow

  I'm looking for a Windows 7 and XP compatible Windows desktop panning/scrolling tool. This is to solve a problem where some applications for example MSN have settings/preference Windows that are not resizeable. I have a Netbook with a small maximum screen resolution e.g. 1024x600. The fixed non-resizeable windows are too large for this display screen size so I cannot see all of the items on these windows, particularly the OK button to save settings. What I would like is a desktop scrolling/panning tool where if I move my mouse pointer to any edge of the display, it pans to show the region of the too-large-fixed window that I could not see. I use a Samsung N110 and Toshiba NB100 netbooks. I'm looking for: A general program that provides desktop panning/scrolling/expanded resolution to allow all regions of a non-resizeable fixed window Preferably a non-graphics hardware specific program but will accept a solution that works with both the above machines I'm NOT looking for (i.e. unsatisfactory answers others have asked that I've already searched and found): Advice on what programs to use that DON'T have the problem of fixed windows Alternative operating system solutions Plugging in an external monitor with larger resolution - I use this option but I need a solution when one is not available, e.g. while travelling etc Advice about not using small screen netbooks - I enjoy the compact convenience of them Advice about change the dpi settings in the Control Panel Display settings Advice about guesswork with the tab key to move the focus the off-screen item I cannot see Thank you in advance.

• XenServer 5.5 running WHS.. trying to add local or network printer/scanner/copier

  - by ProstheticHead

  Hi guys. Just wondering if anyone has prior experience in sharing a multifunction printer across a (mostly windows) network? My situation at the minute is complicated.. I DID have the printer attached directly to a Windows Home Server box and was able to scan to a share and print across the network from my other computers. Compatibility problems have forced me to virtualize WHS on XenServer 5.5... This is actually quite useful because I can now run other things on the same box, but the problem is that now WHS doesn't get direct hardware access so it doesn't see a USB attached PSC... Grrrr! So now I have a choice to make. I've read somewhere that I can buy an add in PCI USB controller and somehow set up a passthrough to one VM at a time. To me, this sound complicated but if it's likely to work reliably I'd prefer this method. I've read about another approach, which I'm not sure about either, but I guess sounds plausible. A Network USB server, (NOT a print server) that can somehow make a USB port accessible across a network. My worry here is that it likely needs some kind of 3rd party software to work.. so not ideal. If there are any other methods you can suggest I'd be happy to hear them... I need your help guys. I'm also in the market for a PCI express SATA controller, nothing flashy, just need up to 8 ports, JBOD and 100% compatability.. Any suggestions? Regards Kevin

• What is the max connections via remote desktop for a small server?

  - by Jay Wen

  I have a small server running MS Server 2012. The CPU is a Xeon E3-1230 V2 @ 3.30GHz, 4 Cores, 8 Logical Processors, 8 GB RAM. Main HD is a Samsung 840, and the big storage is a 4 disk WD Black Raid 10 Array in a Synology NAS enclusure. My question is: given this hardware, approximately how many users can the system support via "Remote Desktop Connection"? Assume there are no licensing limits. These are not admin users. I know there is a two admin limit. This boils down to: What resources does one remote connection require? RAM? % of the CPU? Networking bandwidth? I guess the base case would be for a conection where the user is inactive or simply browsing cnn. Once you know this, you know how many you could fit on the machine before something is maxed-out. In reality, users would be mostly on Excel (multi-MB spreadsheets). I know the approx. resources currently required by each copy of Excel.

• Google Drive terminates without error on startup

  - by Iszi

  I've used Google Drive for awhile now, but it won't start up after installing on my latest system re-build. I'm still using the same OS, hardware, and basic software load (antivirus, firewall, etc.) that I have for years during which I had not previously had problems with Drive. OS: Windows 7 Ultimate x64 Google Drive Version: 1.12.5329.1887 Now, whenever I try to run Google Drive, it just spawns two instances of the executable which die shortly after. No error messages are posted to the desktop, and nothing indicating any problem is written to the Event Log. After some research, I've yet to find anyone having the same problem who's found an answer. I did find out how to run Google Drive in diagnostic mode, using the --vv parameter at the command line. After that, I opened up the sync log and got this: 2013-10-31 17:11:24,039 INFO pid=3664 1892:MainThread logging:1600 OS: Windows/6.1.7601-SP1 2013-10-31 17:11:24,039 INFO pid=3664 1892:MainThread logging:1600 Google Drive (build 1.12.5329.1887) 2013-10-31 17:11:24,039 DEBUG pid=3664 1892:MainThread logging:1608 DEBUGGING DUMP is ON. 2013-10-31 17:11:24,051 ERROR pid=3664 1892:MainThread logging:1575 ERROR, UNEXPECTED EXCEPTION 2013-10-31 17:11:24,051 ERROR pid=3664 1892:MainThread logging:1575 [Error 5] Access is denied Traceback (most recent call last): File "<string>", line 232, in Main File "<string>", line 118, in RegisterCustomFileTypes File "P:\p\agents\hpal4.eem\recipes\353983091\base\b\drb\googleclient\apps\webdrive_sync\windows\build\pyi.win32\main\outPYZ1.pyz/windows.registry", line 62, in GetValue WindowsError: [Error 5] Access is denied 2013-10-31 17:11:24,052 INFO pid=3664 1892:MainThread logging:1600 Crash reporting disabled.

• How do I find the cause for a huge difference in performance between two identical Ubuntu servers?

  - by the.duckman

  I am running two Dell R410 servers in the same rack of a data center. Both have the same hardware configuration, run Ubuntu 10.4, have the same packages installed and run the same Java web servers. No other load. One of them is 20-30% faster than the other, very consistently. I used dstat to figure out, if there are more context switches, IO, swapping or anything, but I see no reason for the difference. With the same workload, (no swapping, virtually no IO), the cpu usage and load is higher on one server. So the difference appears to be mainly CPU bound, but while a simple cpu benchmark using sysbench (with all other load turned off) did yield a difference, it was only 6%. So maybe it is not only CPU but also memory performance. I tried to figure out if the BIOS settings differ in some parameter, did a dump using dmidecode, but that yielded no difference. I compared /proc/cpuinfo, no difference. I compared the output of cpufreq-info, no difference. I am lost. What can I do, to figure out, what is going on?
