  • Internet Troubles - PPPoE vs PPPoA?

    - by AkkA
    I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again. I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine. It wasnt. I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped. Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE? If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

  • Radeon 6950 - Garbling of text and graphics in certain Windows only

    - by Greg
    This morning I noticed the text in Gmail (in Firefox 4) looked a little funny (kind of thin, maybe some color fringing). I went to work and thought it might be some ClearType issue or something with the way Direct way that FF4 draws to the screen. When I came back from work (I left the computer on), the problem was much worse - way beyond ClearType nit-picking. The text was barely readable. I opened Chrome and there was no such problem. It seems like only Windows that use hardware acceleration are garbled, and ones that use GDI are not. But, I fired up Dragon Age and didn't notice any problems (I only really looked at the main menu though). Here is a link to a screen shot that illustrates the problem. Notice how the Windows Live Mesh window is completely unreadable, the text in Firefox 4 (left) is pretty bad, while Chrome, the Windows Control Panel, and the task bar are perfectly fine. The fact that the problem shows up in screen shots and that it only happens in certain Windows makes me confident that the problem cannot be with the monitor or DVI cable. I am using the AMD Radeon drivers from 4/27/11. The card I have (MSI Frozr II) came with a slight overclock (810Mhz) out of the box, but it looks like when I'm on the Windows desktop it's not running at full clock (CCC reports 450Mhz). Still, I underclocked it to the stock reference clock (800Mhz) and it made no difference. The idle temperature according to Afterburner is 42-44 Celsius, which seems a tad high but not enough to cause a problem - it's cold to the touch if I open up the machine. What the heck could be causing this? The problem varies in intensity. As we speak I'm in Firefox and things look better than they did earlier - it'll probably get worse again soon.

  • Data Store/Volume disconnecting. How to resume copy of VMDK?

    - by Serge
    I'm having an issue with my ESXi 4.1 hosts losing the datastore with FC SAN after a power outage. All 3 hosts disconnect so it's definitely a SAN issue. I've tried to resolve the issue on the SAN side with the SAN software support and Adaptec hardware support. No luck there. So I'm stuck with a SAN that will randomly disconnect the volume. I need to get the virtual machines (VMDK files) from the datastore. The problem is I can only get 5-20% before the data store disconnects. I have backups that are slightly older that I can use to replicate the VMDK differences to. What has not worked so far: Powering up the VMs, will boot up for 5-15 minutes then freeze vCenter migrate or clone of VM, will fail after similar period of time vCenter copy/paste of VMDK. Was able to get one 30GB VMDK and no luck after that. vMware Data Recovery. Fails at low %, can't resume, so next backup starts from begining. Veeam Backup & Recovery. Same as above, no resume function. If I can just find a backup solution that will resume from the failed spot that would solve my issue. Anyone have any ideas that I could try? EDIT 1 The SAN is Open-E DSS 6 running on a Supermicro 24 drive enclosure with 4 port Qlogic FC. Adaptec 52445 RAID card.

  • How can I control which sound card Ubuntu uses for playback?

    - by GorillaSandwich
    I am dual-booting Ubuntu 9.04 and Windows XP but am new to Ubuntu. In Windows, I use an M-Audio Audiophile 2496 sound card for recording (because it has RCA input jacks for my mixer), but I don't use it for playback (because my speakers use a 1/8 inch jack); instead, I use the motherboard's built-in sound card. I tried to recreate this arrangement in Ubuntu, but despite selecting the built-in card for all playback under System > Preferences > Sound, I still have inconsistent results. Rhythmbox plays back through the integrated card, but Flash content in the browser and games in the OS send their audio to the Audiophile card. I have seen recommendations to use a program called "Jack" to control this, but I installed it and found it baffling. How can I control which card is used for playback, other than disabling one card (as I discovered how to do and explain below)? Also, is there a GUI for disabling hardware, or is it necessary to edit a configuration file?

  • Netgear FVS336G: appropriate solution for today's small businesses?

    - by bwerks
    Hey all, I've been looking into a routers to facilitate a vpn solution for a small business. While the Netgear FVS336G looks good on paper, it appears to have some fairly crippling setbacks that drag down what appears to be some great hardware. First off, the unit has been around for a couple years now, perhaps before 64-bit operating systems were as common as they are now, and complaints are everywhere that claim that SSL or IPsec (or both) VPN connections will not work with 64-bit operating systems. However, most of these claims mention only Vista, which makes me think that these problems could have potentially been solved since then. Unfortunately though, Netgear's support forums seem to be incredibly private, and policed by some troll named jmizuguchi who just closes down public posts in order to marshal them into the private ones. Danger, will robinson. Apparently their firmware upgrade process is a nightmare too, but that's beside the point. My question is this: has anyone configured one a Netgear FVS336G to operate in a server 2008 (or R2)/windows 7 64-bit network? If so, is it possible to use the microsoft vpn client or are third party clients still required? If this thing has just failed the test of time, is there a feature-comparable unit that I've missed, at anywhere near the same price range? Thanks!

  • mkfs Operation Takes Very Long on Linux Software Raid 5

    - by Elmar Weber
    I've set-up a Linux software raid level 5 consisting of 4 * 2 TB disks. The disk array was created with a 64k stripe size and no other configuration parameters. After the initial rebuild I tried to create a filesystem and this step takes very long (about half an hour or more). I tried to create an xfs and ext3 filesystem, both took a long time, with mkfs.ext3 I observed the following behaviour, which might be helpful: writing inode tables runs fast until it reaches 1053 (~ 1 second), then it writes about 50, waits for two seconds, then the next 50 are written (according to the console display) when I try to cancel the operation with Control+C it hangs for half a minute before it is really canceled The performance of the disks individually is very good, I've run bonnie++ on each one separately with write / read values of around 95 / 110MB/s. Even when I run bonnie++ on every drive in parallel the values are only reduced by about 10 MB. So I'm excluding hardware / I/O scheduling in general as a problem source. I tried different configuration parameters for stripe_cache_size and readahead size without success, but I don't think they are that relevant for the file system creation operation. The server details: Linux server 2.6.35-27-generic #48-Ubuntu SMP x86_64 GNU/Linux mdadm - v2.6.7.1 Does anyone has a suggestion on how to further debug this?

  • Migrate Windows Server 2008 to a new hard disk

    - by MainMa
    Hi, I have a machine with Windows Server 2008. I want to change the hard disk drive, but keep everything else. I don't have a cd/dvd drive and don't want to buy it. My first idea was to make a byte-to-byte copy of the disk with Paragon Advanced Recovery. The problem is that when I try to boot from a new hard disk, it says that there were hardware changes and that Windows must be repaired, inviting me to insert the installation disk and follow repair instructions. I searched and found that 1:1 copy is not a correct way to do things. The correct one is to restore Windows to a new hard disk from a full system backup. But to restore, I need to have a dvd drive. I tried to make a copy of the Windows Server 2008 .iso on an USB flash drive, but the drive is not bootable (while the same procedure applied to Paragon Advanced Recovery ISO produces a bootable recovery USB flash drive). Now what else can I do (except buying a dvd drive)? Is there a way either to make Windows work without doing recovery or recover Windows 2008 without using a cd drive?

  • Windows 7 - Intermittently processes will not close when the app closes

    - by Bill Sambrone
    I have a user I am supporting who has the strangest issue. There are 2 problem applications, Word 2010 and a scanning program called ScandallPro. Intermittently (and at least once a day), she will close an app and the underlying process will not close. Both Word 2010 and this scanning software have all the latest updates. There is another user who has the same software that does not have this problem, and has identical hardware. I have formatted and rebuilt the computer for the user who is having the problems. After the rebuild, the machine was fine for a day but the scanning software continues to intermittently keep the process running even after it is closed. This is a problem because she cannot open a new instance of it while the process is still running. There is a boatload of line of business software on this machine, all of which she needs. I believe the Word 2010 issue is due to a misbehaving add-in (there are 2 add-ins, neither of which seem stable), and I think my best bet is to work with the add-in vendor on it. The scanning program staying open is isolated to this 1 user. The only difference between her machine and the other user is that she has Quickbooks, RoboForm, and Adobe Acrobat X Pro. Any ideas of what can be causing this, or other diagnostic steps to try?

  • How to export SQL Server data from corrupted database (with disk write error)

    - by damitamit
    IT realised there was a disk write error on our production SQL Server 2005 and hence was causing the backups to fail. By the time they had realised this the nightly backup was old, so were not able to just restore the backup on another server. The database is still running and being used constantly. However DBCC CheckDB fails. Also the SQL Server backup task fails, Copy Database fails, Export Data Wizard fails. However it seems all the data can be read from the tables (i.e using bcp etc) Another observation I have made is that the Transaction Log is nearly double the size of the Database. (Does that mean all the changes arent being written to the MDF?) What would be the best plan of attack to get the database to a state where backups are working and the data is safe? Take the database offline and use the MDF/LDF to somehow create the database on another sql server? Export the data from the database using bcp. Create the database (use the Generate Scripts function on the corrupt db to create the schema on the new db) on another sql server and use bcp again to import the data. Some other option that is the right course of action in this situation? The IT manager says the data is safe as if the server fails, the data can be restored from the mdf/ldf. I'm not sure so insisted that we start exporting the data each night as a failsafe (using bcp for example). IT are also having issues on the hardware side of things as supposedly the disk error in on a virtualized disk and can't be rebuilt like a normal raid array (or something like that). Please excuse my use of incorrect terminology and incorrect assumptions on how Sql Server operates. I'm the application developer and have been called to help (as it seems IT know less about SQL Server than I do). Many Thanks, Amit

  • How do you recreate the System Recovery environment in Windows 7?

    - by Howiecamp
    I'm running Windows 7 Home Premium RTM (64-bit) and I want to take advantage of the system recovery tools (eg the Command Prompt) without using the Windows 7 DVD. My understanding is that this environment (WinRE) should be installed to your HDD by default as part of the Windows 7 installation. However, when I hit F8 on boot and select "Repair", I get: Windows failed to start. A recent hardware or software change might be the cause. To fix the problem... Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible. The "Info" line seems like the smoking gun. My next step was to boot from the Windows 7 DVD, and choose "Repair". It indicated my Recovery Environment wasn't on the Windows 7 boot menu (perfect) and offered to fix it. I said yes and rebooted, however same issue as above. In addition, when I booted in to Windows 7 and I looked at the boot menu options, the recovery/repair option was not there. Only my Windows installation. Finally, I ran the Disk Management tool (diskmgmt.msc) and took a look at the contents of my "System Reserved" partition (which was set to "Active" as normal). It's unclear to me what the contents should look like, however it is my understanding that the WinRE environment gets installed to this partition. (As part of the above troubleshooting I followed http://superuser.com/questions/25728/how-to-fix-windows-7-boot-process which lead to http://www.sevenforums.com/tutorials/668-system-recovery-options.html).

  • Outbound mail issue during Exchange 2003 migration

    - by user27574
    Dear all, I am having an outbound email issue during the Exch 03 migration. Basically, we are migrating Exch03 to new hardware, both servers are Server 03 based. Everything runs smooth while setting up and installing Exch 03 on the new box. Public folders are all replicated. My issues are shown below.... 1) After starting to move users' mailboxes to new Exch 03, they receive some undeliverable mail and bounced back mail from some vendors, then I move few users back to test around, they have no problem at all after moving back to old Exch 03. 2) Another issue is our company has Blackberry users, we don't have BES. Under each user's mailboxes, we have forward rule setup, so that both user inbox and BB can receive email. User who is moved to the new Exch 03 server, they can only send email to the BB user's inbox, mail cannot be forwarded to BB at all, smtp queue stacks up and keep trying until the time is expired. Since not all emails that the users send out from the new Exch have problem, I am not able to narrow down what is the issue here. Can anyone give me some ideas? Could this be MX record / Reversed DNS relate? Or firewall NAT rule setting? Thanks.

  • OpenVZ: Choosing right MySQL-Server depending on host

    - by Scheintod
    What I have: Two servers running Wheezy/OpenVZ with One MySQL container on each host master/master replicated (mysql1/mysql2) Replicated DNS on each host (dns1/dns2) different web-containers on each host but regulary backuped to the other. What I want: Each container should use the "local" MySQL-Server (the one which runs on the same hardware-node). I'd like to be able to move the web-containers between the to hosts. Each container should choose the MySQL-Server (semi) automatically. This scheme should continue working if one host is down. What I tried: Currently I'm keeping track on which container should run on which host by DNS entries which are queries by scripts e.g. for questions like: "Which container should be backuped on/to which host." For choosing the right MySQL server I have one extra entry like "mysql.container_abc" which resolves to either mysql1/mysql2. So in the applications in the container I can use "mysql.container_abc" for e.g. mysql_connect and if I want to move the container around I just need to change the dns. Now I notices one problem with this approach: Every mysql_connect generates one DNS query because the dns is not cached and this slows the request down unnecessarily. What I would like better: Some way of passing the information on which host we are running to the container and using it directly instead of using DNS. E.g. some way of setting a custom /etc/hosts entry in the container. Or any other great idea. Doesn't have to include DNS but shouldn't require to much special "magic" inside the container.

  • How can I update generic non-pnp monitor?

    - by njk
    Background I've been running a KVM switch with my monitor at 1920 x 1080 over VGA for over a year. Did a Windows Update on 12/11/12 which did the following: Update for Windows 7 for x64-based Systems (KB2779562) Security Update for Windows 7 for x64-based Systems (KB2779030) Cumulative Security Update for Internet Explorer 8 for Windows 7 for x64-based Systems (KB2761465) Windows Malicious Software Removal Tool x64 - December 2012 (KB890830) Security Update for Windows 7 for x64-based Systems (KB2753842) Security Update for Windows 7 for x64-based Systems (KB2758857) Security Update for Windows 7 for x64-based Systems (KB2770660) After a restart, my extended monitor was dark. I attempted to reset the extended display configuration, and noticed my monitor was being detected as a Generic Non-PnP Monitor: I uninstalled, downloaded new, and re-installed display drivers. Nothing. I attempted to unplug my monitor from the power for 15 minutes. Nothing. I followed some of the suggestions on this thread; specifically DanM's which suggested to create a new *.inf file and replace that in Device Manager. Device Manager said the "best driver software for your device is already installed". The only thing that works is when the monitor is directly attached to the laptop. This obviously is not what I want. My thought is to somehow remove the Generic Non-PnP Monitor from registry. How would I accomplish this and would this help? Any other suggestions?

  • How do I install a different OS on a Compaq Presario cq56 with preinstalled SuSE 11?

    - by McCoy
    Thing is, I don't have a clue of Linux systems, I usually use WinXP. Bought a notebook with SuSE 11 on it, because I have my XP licence and thought I could install that if I found the chipset drivers for the hardware (which I'm not completely sure I have the right versions of). Then I thought I'd give it a shot with the SuSE, looked nice enough. But I can't get my external hd to work (tried force mount) and the banshee doesn't do anything like playing video. Since that is one of the two main purposes of this notebook, I need to get that to work. Tried downloading VLC player, but that only works with SuSE 11.1 upwards. So I downloaded a SuSE 11.3 and burned the iso. But surprise, no way the notebook would boot from cd. Same with the XP cd (considered setting up a dual boot). And no, I can't get to BIOS to reset to default, either. So I can basically do nothing else than going online with this thing and that's not enough for me (gamer in withdrawal, yikes!). I need at least to get to my firefox profile on the external hd and be able to watch video. Can somebody please help me? I think at this point I'd prefer to install XP and MAYBE the SuSE 11.3 after that. I'm not a native speaker, so please speak plainly, thanks. :) Edit: if this is impossible, could someone please help me with the external hd mount and video playback? Edit: Found out how to boot from cd by now. But still no XP, because I get bluescreen after bluescreen while setup is loading files. I guess it's the missing SATA drivers...

  • Need help trying to diagnose Symmetrix SAN performance issues

    - by arcain
    I am helping to benchmark hardware for a new SQL Server instance, and the volume presented to the OS for the data files is carved from a set of spindles on a Symmetrix SAN. The server has yet to have SQL Server installed, so the only activity on the box is our benchmarking. Now, our storage engineers say that this volume and it's resources are dedicated to our new server (I don't have access to see the actual SAN config) however the performance benchmarks are troubling. For example, the numbers look good until suddenly, and randomly, we see in our IO benchmarking tool wait times of 100 seconds, and disk queue lengths of 255 in perfmon. This SAN has an 8 GB cache, plus there are other applications besides ours that use the SAN. I'm wondering if (even though the spindles for our volumes should be dedicated to us) the cache may be getting hammered during the performance testing, or perhaps the spindles our volumes are on aren't really dedicated to us. We're not getting much traction from our storage engineers in helping us track down the problem, so if anybody has experience with diagnosing a problem like this and would like to share insights and troubleshooting methodologies, I'd appreciate it.

  • Screen Flicker on a black MacBook

    - by sixtyfootersdude
    I have a MacBook Black. For about the last six months I have had a strange screen flicker when I: start my machine and plug in the power cord of my machine This morning when I woke up my computer the screen backlight did not turn on at all. When I held the computer in direct sunlight I could see the screen and I could tell that everything was working normally (other than the backlight). Pressing the screen brightness controls (F2) brought up the brightness panel. The brightness panel informed me that the screen was at maximum brightness. I did a bit of Searching and this is what I found: This post describes how to buy and replace a macbook screen. Do you think that this would solve my problem? Additional info: I am running 10.6.4 I recently upgraded from 10.4. I experienced similar issues in 10.4. I am pretty sure that this is a hardware issue. The problem does not occur when the screen is at a specific angle. It usually only happens at startup/wakeup or when the power is plugged/unplugged.

  • Network access lags for Win7 when server network utilization is high

    - by Jeff Miles
    We have a Dell PE2950 file server running Windows 2008, hosting a DFS namespace of ~1.2 TB. This server has two Broadcom 1Gbps NICs teamed together. When there is high traffic going to the server across the network (greater than 200 Mbps), any Windows 7 client accessing a DFS share at the time experiences severe performance problems. For example: Computer A has an AutoCAD drawing opened directly from the DFS share. Performance is normal, not causing any issues. Computer B begins a file transfer, putting a 11GB file onto a different DFS namespace, on the same server Computer A immediately notices lag while using AutoCAD. The cursor momentarily freezes within AutoCAD every 10 seconds or so, and any browsing of the DFS share is extremely slow. Computer B completes file transfer, and performance resumes to normal for Computer A. This is only affecting Windows 7 clients, using a variety of hardware (desktop + laptop). All of our Windows XP clients see no performance impact during the file transfer. Things I have tried with no change: Had Computer A work from an entirely different RAID array from the file transfer destination Updated NIC drivers on clients and server Enabled TCP offload and receive side scaling on the server NIC (previously disabled when the issue began) Antivirus disabled during file transfer I am currently having a user test applications other than AutoCAD when the file transfer occurs, and will update the question with that result. Does anyone have any recommendations for resolution or additional troubleshooting steps?

  • Windows 7 BSOD when I walk away from the computer

    - by bobobobo
    I have a really weird experience with this new AM3 box I set up. Everything seems fine at first. But now I get frequent (daily) BSOD's, mostly when I walk away from the computer for more than 5 minutes (when the computer is idle). The BSOD's as shown by BlueScreenView almost always have to do with ntoskrnl.exe, and they'll do with really normal sounding operations, like SYSTEM_SERVICE_EXCEPTION, NTFS_FILE_SYSTEM, DRIVER_IRQL_NOT_LESS_OR_EQUAL, KMODE_EXCEPTION_NOT_HANDLED, BAD_POOL_HEADER - You name it. These are basically them, and they repeat after that, just random order. Its not like one is more consistently the problem than the other. I have Windows update ON and I let it do its updates everytime it wants to. I turned windows indexing service off, but it seems Windows 7 does a lot of background processing when I'm away - I'll come into the room and the fan will be going nuts (I'm pretty sure this isn't because the computer flies into a panic whenever I leave). I tried finding updates for my ASUS, and really there isn't much to install (except some new driver firmware). I'm going to install that to see if it helps, but what else could it be? Is it possible its a hardware issue with the board? Or is every Windows 7 user experiencing daily BSOD these days that I don't know about?

  • Can a folder on a NAS be made available as a physical drive in VMWare?

    - by asbjornu
    We are currently in the process of moving from a single web server to two load balanced web servers and are facing some challenges we don't quite know how to fix. One of these is that the current single server hosts applications that write stuff to disk. The applications running on the server expects that when something is written to disk it later will in fact exist, so it's important that this premise is fulfilled with the dual server architecture as well. The dual server setup is a couple of VMWare instances with Windows Server 2008 R2 as the guest operating system. Out of the box, these instances does not share any kind of file system, so just moving the applications over would make them break since one instance would write something to the file system that doesn't exist on the other. Thus we need to share a file system between the two virtual servers. Our host has proposed to create a network share on a SAN and map this share individually on each virtual machine. This doesn't work too well due to NTFS permissions, etc., because the share needs to be accessed by several independent web applications that won't even be in the same application pool. The only solution that kind of works is to hard code an "identity" for each web application into its web.config file, but this means password in clear text which doesn't sit well with me. Since the servers are virtual, I'm thinknig: Wouldn't it be possible to make a NAS area available as a physical disk in the gues operating system somehow? Since VMWare has full control of the virtual hardware, you'd think it would be able to "fake" a local hard drive in the virtual machine that in reality is a folder on a NAS, but so far I haven't found anything that states how and if this is possible. So I have to ask the wonderful Server Fault community: Can a folder on a NAS be made available as a physical drive (typical D:) in both of the virtual machines?

  • WRT54GL Tomato Router in Client wireless mode to an iPhone Personal Hotspot

    - by Gordo
    I am trying to connect a router with Tomato firmware to an iPhone 4. The goal is to connect to the Personal Hotspot in Client Wireless mode. This should allow wired and wireless users to connect to the router rather then the iPhone. In theory this should be possible but I am having difficulty. Router Linksys WRT54GL Tomato 1.28.1816 firmware iPhone iPhone 4 iOS 5.1 (9B176) Carrier Rogers Wireless Personal Hotspot works with other devices, wifi/bluetooth/usb iPhone Personal Hotspot settings Mode: B/G Security: WPA or WPA2 Personal Encryption: AES Router IP: 172.20.10.1 Subnet: 172.20.10.0 Min IP: 172.20.10.2 Max IP: 172.20.10.14 maximum number of wireless tethered hosts is 5 I have followed the directions here: http://www.wi-fiplanet.com/tutorials/article.php/3810281 Ensured that the router subnet does not 'collide' with the iPhone subnet. Here is the configuration of the Tomato 'Basic - Network - Wireless' section: http://i.stack.imgur.com/pbmTB.png I have tried several variations of this configuration, but nothing seems to work. NOTE: I have successfully connected to my own wifi network in Wireless Client mode, so I am confident that there are no bad cables or other hardware issues. I would prefer to use Tomato, but DD-WRT maybe my only other option. Thanks!

  • Are flash drives and hard drives thought of as "an ocean of bytes"?

    - by Jian Lin
    Why can a USB Flash drive be formatted as NTFS or FAT32? Is the USB Flash Drive and Hard Drive just to be thought of as "an ocean of bytes"? I get very used to hearing formatting a hard drive as FAT32 or NTFS, but we can also format a USB Flash drive as NTFS or FAT32? Is it because a hard drive or Flash drive both can be thought of as "an ocean of bits" or "an ocean of bytes"? I remember RAM as: it takes 16 bit or 32 bit as an address signal (the 16 or 32 copper footing on the circuit board), and give out 8 bit of data (the other 8 copper footing on the circuit board). So can a hard drive be thought of as working that way too? So that's why a Flash drive can be the same too? Just an "ocean of bytes". But is it true that hard drive's hardware make it an ocean of sector or something else, that is, the smaller unit of read / write is not byte but something else? So with this "ocean of bytes", NTFS has the format that says, "if the first byte is __, then it means __ (it is a file or folder, and link to which sector, indicated by byte 2 and 3, etc, etc)"

  • Windows Server 2012 Hyper-V very slow

    - by Matt Taylor
    I have been running several Hyper-V VMs on Windows Server 2008 R2 for the past couple of years and enjoying perfectly adequate performance for my testing/development/r&d environments. I'm a software developer so my hardware knowledge is basic however I built the rig using: •Gigabyte GA-X58A-UD3R Intel X58 (Socket 1366) DDR3 Motherboard •Intel Core i7 960 3.20GHz (Bloomfield) (Socket LGA1366) •24GB triple channel RAM The host OS is running on an OCZ SSD and all the VMs are running on a 2TB Marvell SATA3 RAID 0 array consisting of 2 Western Digital Caviar Black 7,200rpm drives. I have tested the speed of the 2TB drive and appear to be getting less than 3Mbs but it can adequately run a 4 VM farm including a DC, (SQL) database and IIS application servers. I recently upgraded the SSD on which the host runs to a 256GB OCZ Vertex 4 and took the opportunity to upgrade to Windows Server 2012 and installed the Hyper-V role. I tried importing one of my existing Windows Server 2008 R2 VMs (and converted it to .vhdx) plus I have tried creating a brand new Windows Server 2008 R2 VM but both are running extremely slowly and I can see nothing obvious using the host and guest Task Manager/Resource Monitor tools. In both cases the VM has 8GB RAM (fixed), 4 CPUs, fixed size HD (not expanding) and is using an external virtual network running on a separate NIC to the host. I have upgraded the BIOS to the latest available version and checked the virtualization settings. I have run out of "obvious" (to a developer) things to check/configure and my next option will be to re-install the host OS but before I do I would very much appreciate any advice from any experts out there. Thanks

  • How does one skip "Windows did not shut down successfully" in Win7-64?

    - by XenonofArcticus
    Migrating an app from an expensive and unreliable dedicated embedded x86 box running WinXP-embedded to COTS hardware (Dell E6410 laptop) running normal Win7-64. At this time, it's not feasible to deploy using Windows 7 embedded. The problem is, that the system is still sort of "embedded". The power could shut off at virtually any time without prior warning. We've stripped the OS down and removed the battery capability so that it will power down as desired. The app never writes to the disk, so it's not like we're going to corrupt anything terribly. The system is essentially idle after our app is up and running (with the exception of some computation, graphics, and TCP/IP and serial communications) so the OS enters a pretty stable state rather quickly. After a power-loss however, it rightly complains that Windows did not shut down successfully and presents the user with the Windows Error Recovery text screen. If left alone, it does eventually move on booting just fine, but we'd like to skip that step if possible. WinXP-embedded is designed to do this automatically, so I know it's possible. I've looked at the Kernel Switches but I didn't see anything documented for "Skip Windows Error Recovery". I've also read extensively on the startup process: http://homepage.ntlworld.com./jonathan.deboynepollard/FGA/windows-nt-6-boot-process.html I know I can disable the auto chkdsk in the registry, but that's not the same thing either. So, how do I streamline the boot process to not hassle the user about a situation that will be the regular normal situation?
