• Can I use dis-similar HW for Win2008r2 DFS-R

  - by cwheeler33

  The setup: Windows 2008R2 Ent on two machines. The roles on each server will include File Servers and DC's. The machines come from two different vendors (Dell/HP) The Dell is an Athlon and the HP is an Intel. Both have roughly the same speed CPU and 8GB of RAM. They have different Raid controllers, and more or less the same amount of disk space (roughly 6TB.) Can the servers use different types of hardware? Is there any documentation about this? The last question I have is about the network. Can DFS-R be forced to use a differen subnet from the regular network?

• Grub hangs intermittently on "Starting Up..."

  - by Griffo

  Hi all, I've had this problem for a while now. My linux server is set to wake-on-lan but occasionally it halts at Grubs "Starting Up..." and goes no further. This is not due to additional hardware being attached such as a flash drive or anything as I never plug anything into it. It may boot perfectly 40 times in a row and then hit this issue. Sometimes it gets the issue a couple of times in quick succession and doesn't happen for ages again. I'm not sure how to diagnose it since it doesn't seem to be reproducible. Any help much appreciated. Thanks

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• bad switchs duplicate my ip

  - by tacoen

  I had a large area LAN. There were many switch and AP on it, then somehow I couldn't ping my servers, and it's said that the IP was duplicated. I use arpwatch and found out that one of the switch flip-flop-ing the IP. I isolated that troublesome switch using his mac-address. But, since this a large area LAN... I doubt this will be the last cases. If there any software or hardware that I can use to prevent this kind of error? Sorry for my bad English.

• Laptop won't load an OS or even an OS setup.

  - by Talasan Nicholson

  My fiancé's laptop started to crash and would get BSOD errors to the point that she couldn't even boot up because it would either take forever or just crash. So I figured I'd try to reformat, as it's done this before and this was the solution last time. On Windows 7, it will not go passed the "Setup is starting..." screen. On Windows XP, it crashes once the setup is about to start (BSOD). I shut it down and let it sit for 5+ hours, in case it was overheating, but it's doing the same thing anyway. By now, I figure it's something to do with the hardware but I hope not. Any ideas?

• How to put fear of God (law) into Wi-Fi hacking neighbors [closed]

  - by Shakehar

  I live in an apartment and some new guys have apparently moved into one of the apartments. They have been shamelessly hacking into my WiFi. Mine was initially a WEP encrypted network and out of laziness I just limited and reserved the IPS on my router for the people in my house. Yesterday I had to free up an IP for a guest in my house but before he could join the network these guys connected in. I have changed my encryption to WPA2 and hope they dont have the hardware/patience required to hack into it, but there are many wi-fi networks in my apartment most of which are secured using WEP. I don't really want to call the police on them. Is there any way to deter them from misusing other people's wi-fi ? I have gone through I think someone else has access to my wireless network. What next? but I have already taken the steps mentioned there.

• Can a RAID disk setup crash if only 1 hard disk fails?

  - by Steve Rodrigue

  I am a web developer. I have not much experience in hardware. For this reason, I use managed servers. This morning, one of the drives in our setup failed. However, the full site went down. I asked my web host what happened and he replied that the hard disk failed in such a way that the RAID controller couldn't work properly. Do you guys ever seen that before? Is it possible? Thanks for any help on this guys. I need to know if my web host is honest with me. Steve

• Hylafax with serial over IP modem

  - by zero_r

  I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

• Is it a good idea to take onsite/offsite backups of server images?

  - by ServerAdminGuy45

  Assuming a non-virtualized environment it a good idea to take actual images of servers (using something like Acronis True Image) and store them on\off site? Backing up data is great but I feel it would be good to have copies of OS images in the event hardware dies or an upgrade gets botched I can always revert back. What would be your recommended way to do this (preferably using a NAS and an online backup service)? I was talking with the Iron Mountain folks and the service they described is more geared toward taking incremental snapshots of data. I'm not sure if there's a way to backup images in an incremental way such that only the changes between them are saved (that way I'm not wasting X GB each time I take an image).

• Little server for a little network: Asus TS Mini + Windows Home Server or other?

  - by microspino

  Hello, I'm building a little network with 4 computer a plotter, 3 printers an a HP Fax/Scan/Copy/Print machine. The network is connected to the web by a D-Link router/firewall. I would like to add little server to have file sharing (reachable via VPN from outside by a single user-road-warrior), automatic backups. I would like to avoid big electrics bills or, to say It in a green way, I would like to avoid useless power consumption made by a big server with hot-plug, Raid, double PSU because I don't need all this stuff. The server must work 24/7 and the budget is between 400€ and 1000€. I'm evaluating the Asus EEE Box (with XP), a TranquilPC (with XP), a FitPC (again with XP), and an Asus TS Mini (with Windows Home Server). I like the latter but since I'm Europe I don't know where I can buy It. Do you have any suggestion/experience to share with me about: which hardware do I have to buy ? which O.S. ?

• XPS M1730 Freezing & Crashing unexpectedly

  - by evesirim

  I have a Dell XPS M1730, freshly installed with Windows 7 Professional 32-bit that every so often crashes completely unexpectedly. It need not be running any applications at all for this to happen, never mind anything particularly intensive. It also clearly is not a BSoD issue as no Minidump files are being created in the process. All drivers are up to date and have been both rolled back and then updated and the Device Manager reports no issues. There are very few applications installed on the machine and it has only been online once. It runs a minimal boot of Win7 and yet still after all of this something is making it crash. All of this suggests to me it may be more like a hardware problem but to be honest I really have no idea - so I thought I'd try here. Any thoughts...? Many thanks in advance

• Can DVI look different?

  - by queueoverflow

  I have a desktop with an nVidia GT 9500 which has two DVI slots. I have a 24" TN-Panel TFT on that and it looks pretty good. Then I hooked it onto the DisplayPort of my ThinkPad with the Intel HD 3000 card with an DP-DVI adapter and I think that the fonts look even clearer. Both computers run Kubuntu 12.04, although the ThinkPad is freshly set up, while the desktop is migrated from the previous release. Is this a hardware thing or is it just some setting in the anti-aliasing or sub-pixel-hinting?

• Would there be any problems with DEP turned off?

  - by IneedHelp

  I recently moved to a fresh Windows 8 x64 system and I learned that my favourite firewall (JPF - Jetico Personal Firewall) doesn't get along with Win8x64 (CRITICAL_STRUCTURE_CORRUPTION errors), but I can not do without JPF, so I kind of tried everything I could think of (test mode, debugging, various system changes), but I was still getting blue screens because of the firewall driver/software. I know for sure that it is the firewall that is causing the problems because I get blue screens as soon as I install it and they stop when I uninstall it. I Also tested it thoroughly on virtual computers. Anyway, I have discovered that by completely turning DEP off by using this command: bcdedit.exe /set {current} nx AlwaysOff the firewall would not cause blue screens anymore. So my question is, what could go wrong with DEP completely turned off? Note: I do not care much about hardware/windows security, I keep myself secured by using sandboxes and virtual computers (and I also have backups), so I'm not concerned with viruses and root kits or whatever people are freaking out about.

• Does RAID negatively affect non-RAID devices?

  - by Django Reinhardt

  I am running Windows 8 on an SSD, and it's all running swimmingly, but I want to store documents on two HHDs (not SDDs) running under RAID 1. My motherboard has two SATA controllers, both set to AHCI. On the 3GB/s controller, all four ports are used (1 Bluray Optical Drive, 1 Spare HD, and the 2 I wish to turn into a RAID 1 drive). Windows is on the 6GB/s controller. Like so: So my question is: If I turn these four ports (on the 3GB/s controller) into a RAID controller, will that negatively affect the non-RAID hardware plugged into it? I.e. Will the HDD or Bluray drive be slower/incompatible with being plugged into a non-AHCI controller? Thanks.

• SharePoint 2010 and Excel Calculation Services

  - by Cj Anderson

  I'm curious what the requirements are for Excel Calculation Services in Sharepoint 2010. I found an architecture document but it doesn't list out the specific requirements. (architecture I understand that you can install all the services on one server but it isn't recommended. It then talks about how you can scale up the application servers, and web front ends. What should the hardware look like for both the application server and web front ends? Do I need to setup a standalone box for each application server?

• Recording Interfaces for OS X that are supported/work well?

  - by Troggy

  For os x, I would like to know what other audio production/music recording interface type products people have found to work well with os x? I do not want to know about stuff that only works. I want to know about solid products that work well and are supported well by the company when issues arise. I for example have a M-Audio Firewire Solo recording interface. I have found M-Audio to be a company with great mac support for their products and they integrate well with os x features and apple software. Clarification: I am wondering about the recording interfaces themselves, as in the hardware, that are compatible with os x and supported/work/integrate well.

• Sharing files between multiple computers?

  - by Koalatea

  At my school, we have 13 iMacs that we use to make our yearbook. Currently our school has some servers for us, but since we work with so many files ( thousands of pictures, most of which are ~3MB ) it slows down far too much. Is there a way to better share files between our computers? We are on a wireless network and the whole school shares the same servers, we have around probably 400 computers in the school. Is there a hardware fix I can do? Something like buying an external and hooking only yearbook computers to it?

• Very frequent "Server not found" messages

  - by Village

  Recently, while browsing and clicking or typing an address, I get: "Server not found", "Connection was reset", or a half-loaded page. Usually the page loads instantly after clicking reload, but this means I must reload on every page. Images on one site, but stored at a different server don't load until reloading for a second time. Clicking "submit" on many sites frequently doesn't work unless I reload many times. Sometimes sites load, but without colors and formating, appearing as if they would in Lynx. This seems to happen with every Web site. My Internet service claims everything on their end is fine. This happened a day after running an update in aptitude. I have not updated any hardware. I have tried clearing Iceweasel's cache. I do not have any router or other equipment. What could be going on? How can I troubleshoot this? PPPoE connection, Iceweasel 3.5.16, Debian 6

• "SIOCSIFADDR: No such device" after restoring backup

  - by Paul Tomblin

  I bought some new hardware, and tried to restore my backup on it. When I boot, I don't get a network connection. If I type "ifup eth0" on the command line, I see the messages: SIOCSIFADDR: No such device eth0: No such device lspci shows an ethernet controller (Intel 82546GB). ifconfig does not show any controller except loopback. I tried installing bare Debian on the machine and the network worked then, but now I want to make it like my old machine was. Googling this problem only seems to find people having this problem in VMs. I'm not in a VM.

• Windows freezes, showing a random color or pattern

  - by Manu

  I have a PC with windows 7, and I'm experiencing random freezes with increasing frequency. After some time (from 30 minutes to a few hours) the screen will shows a random color or pattern (vertical lines) and nothing works anymore, I need to reboot manually. I've checked the events log, but nothing is shown except for the unexpected reboot. I've tested the RAM with Memtest86+ 4.20, and the graphics card with FurMark 1.10.3, no errors have been found. I've updated the graphic drivers and openned the case to remove dust, but the issue is still there. Also, the problem doesn't seem to arise when I'm playing games fullscreen, but when I'm surfing the web, using itunes, or coding. My hardware is as follows : intel core i5 750 CPU, ATI Radeon HD 5670 graphics card, ASUSTeK P7P55D motherboard, two 2Gb KINGSTON DDR3 ram sticks, 2 SATA hard drives, a Netgear dongle for wifi.

• Can I run Ubuntu directly under Windows 8?

  - by huahsin68

  Text below is extract from the article, Windows 8 Tip: Virtualize with Hyper-V. Better still, Windows Virtual PC offered a feature called XP Mode, free for users of Windows 7 Professional, Enterprise, and Ultimate, which included a full working copy of Windows XP with Service Pack 3. But the big deal here is that as you installed applications in the virtual copy of XP, they would be made available through Windows 7’s Start Menu. And you could run these applications, side-by-side, with Windows 7 applications on the Windows 7 desktop. It was a seamless, integrated experience, ideal for those one-off application compatibility issues. I was thinking to install VirtualBox in Windows 8 and then run Ubuntu as guess OS. Since Hyper-V is a Type-0 hipervisor, may I know does this bring the same benefit if I have Ubuntu Linux install as a virtual guess OS? Meaning, if I turning the Ubuntu on (the guess OS), does the Ubuntu still able to access the hardware information like nVidia display card or processor information? I'm just curious to know can this be done?

• Exchange Failover Solution

  - by Dan

  I've been given the task to come up with an exchange solution that will support 200 users total throughout 4 states. 1GB per user. It needs to have a failover solution,The failover must reside in another location. There is an mpls that connects the locations. I am hoping to get recomendations on hardware, software setups. I recently worked with some big name reps and they steered me in the wrong direction and now I'm a few days away from my proposal date with bogus quotes and scrambling for a solution. I used to manage a standalone 2003 exchange server for years and am at a loss now with figuring out a clustering/failover...Any help would be greatly appreciated. thank you

• Running multipul lines through a server.

  - by Kevin Roberson

  I am looking to buy numbers in bulk on DIDx.net. After I purchase the numbers in a particular area code, I want to forward those numbers to other numbers that are outside of that area code. This way it will be seen as a local call versus long distance. I have the customers but I don't have the system I need. I have read about Asterisk, VOIP, SIP, and BYOH. But I have no clue what will be the best system for me. Does anyone have any idea what my next step should be when it comes to hardware and software? Or what type of operating system I should use? I basically want to set up a system like GoogleVoice & Phonebooth.

• Why Windows Media Center (Vista 32-bit) unable to record TV Series?

  - by Alex R

  I can record individual shows just fine, but trying to setup the recording of a Series throws an error (something like, "unable to schedule, try restarting Media Center", pops up in the bottom right of the screen). Trying to access the "Other Showings" menu causes Media Center to crash ("check for a solution online" dialog comes up). The machine is a fresh reinstall of 32-bit Windows Vista from the HP recovery CDs, plus all Microsoft updates and service packs. Hardware: HP s3220n, AMD X2 5000+, 2GB RAM, 300GB free space on disk. Media Center came bundled. The "Media Center update for Vista" failed to install (it says, not appropriate for my computer). Any ideas? Thanks
