• Xen VGA passthrough: is it possible to have dual GPU's with single monitor

  - by user489481

  I hate dual-booting between Windows when I want to play a game and Linux when I need to work. I don't fancy running Linux in a VM and Wine almost never works for me. So, I'm thinking about buying a new mainboard and CPU that is compatible with Xen's VGA passthrough and HVM virtualization. I want to be able to switch between the Linux Dom0 and Windows DomU with ease, but the problem is I need two GPU's and have only one monitor. Right now I have a nVidia GTX 260 in my PC, but I also have a Radeon 4850 sitting in my closet that I was going to sell. My question is, can I salvage the Radeon card to run the Dom0 and have the nVidia card run the DomU while having some kind of device/software to connect them a single monitor? Power supply and airflow issues aside. If not, what would you suggest? Is this even possible?

• Windows: Should I install Server or stick with regular?

  - by stalker92

  I hope somebody can help me solve my dilemma. I have my home PC (using Windows 7) which I use for both work and leisure (gaming, surfing, movies etc.) I tend to never turn it off, only when I must reboot because some installation requires me to or when the power gets lost. But, sometimes Windows starts acting weird (usually after the long period of system uptime), per example eats up randomly all the space on my system partition etc. which is solved after the reset by itself. I was thinking to switch to Windows Server, I guess that it is more optimized for long uptime, well, obviously it is meant for use on servers. Can somebody with more experience with this help me decide is it worth it, will it solve these issues connected with long uptime periods? Thanks in advance.

• Windows XP not starting up anymore (BSOD)

  - by Richard

  When I tried to start my computer running Windows XP yesterday, as I turned on the screen it was stuck at the "Welcome" screen. I had to reset it. After that, I got stuck at the point where the BIOS should load the OS - I turn on the PC, the Motherboard and BIOS post message shows up, then the blinking "thing" in the top left corner shows up 2 seconds, then everything is black. After I let it run for some time in that mode, it automatically restarts. I'm writing this here from a Ubuntu 9.10 Live CD. What can I do to fix this? How can I find out what is wrong? I'm a programmer and okay with doing (very) advanced things in that terms, so if you know something just tell me and I'll try

• Radeon hd 5700 monitor blank until connected HDMI device is started

  - by kaido loor

  Have win7, radeon hd 5700. When both PC monitor and HDMI device (Onkyo 607) are connected to Radeon card, the monitor diplays boot info, "starting windows, etc" but goes blank when "log into windows" should appear. Monitor comes back (w normal screen) if Onkyo and TV are turned on, not before. Multiple monitors is disabled. Really crazy. Any help appreciated. Generally, Onkyo can pick up HDMI signal ok, so at least smth works as intended.

• Re-cased my computer now the power plug keeps shorting

  - by dunc

  I've just re-cased my computer. I got the new case free and thought I'd be able to swap everything over myself but apparently I've done something wrong. I'm OK with components generally but wasn't totally confident about doing this. So, my question is, when setting up a new PC or moving old components into a new case, what could I have done which causes the power cable plug to short/fuse when I plug it in?. Is this likely to be an issue with the cables from my PSU, or could it be the internal case connectors? What steps would you take to diagnose the problem? I'd rather not start again if I don't have to...! Thanks in advance,

• encoding movies for the web

  - by ELS

  Hi All, I have a friend that hosts his website on IIS and Windows Server 2003 R2 32-bit. He has .WMV files and .MPG and others and some of these are 30 mb in size! He wonders why users complain the site is slow! So my question is how can we reduce the size of these movies? What software? What settings for bit-rate, etc? Is there free software? I can use either a Mac or a PC. Thoughts are appreciated.

• How To Adjust Properly Brightness And Contrast On Monitor

  - by Johannes

  This days, it seems that I either go worse with my eyes or some settings with contrast and brightness have been changed. However, I have been searching now for some tutorial on how to adjust contrast and brightness, and I have found already some, on how to use Microsoft Win7 Calibrate Display Color program, but some people don't recommend it.. My monitor control menu shows settings (which are by default) that contrast is set to 80, contrast to 90 and sharpnes to 45, for which I belive are pretty dam high. I'm usually every day in front of my PC about 6-10h. The biggest problem is, when the night comes, and I have to read some word document, after a 10-15m of reading, eyes starts hurting. I'm using ASUS VW198 and Nvidia 9800 GT graphic card. So please suggest me, what should I decrease, contrast or brightness or both?

• iTunes Home Sharing with VPN

  - by Philip Crumpton

  I'm trying to set up a VPN on a Windows machine that contains my iTunes library, then connect my iPhone ot it, wirelessly, using Home Sharing (remotly). I have read that this can easily be set up if the iTunes library is on a Mac (Network Beacon and YazSoft ShareTool are two products I found). I can't find anyone who has had success on a Windows machine, though. In my thinking, there are a few options to getting this done. Find a utility that takes care of this for me (like the Mac-only options listed above) and is compatible with iPhone (Hamachi is NOT compatible with iPhone VPN). Manually configure a VPN to allow Bonjour multicast (I'm not sure what this really is...) Emulate a Mac on my Windows PC. FYI my router is a Linksys WRT54GL running Tomato 1.28 Note question is related to this

• Backup solution

  - by user66115

  We are currently looking for a new backup solution. Our current network is 5 remote location with a tape backup in each plant. Right now we are looking at a MPLS VPN and running backups out of our main plant. The main thing that we backup are user private folders and department files. And each plant has it's own file server that houses CAD drawings. My main plan is to have every thing but that CAD drawing at the main faculty. We would start with a main backup of the drawing files and then do change backups back to the main plant. Besides tapes what would be the best way to backup. Our contact at Pc Connection is point us toward a Tandberg Data device.

• ESXI with non standard hardware HDD issues

  - by Hurricanepkt

  I have 3 very underutilized servers that I am condensing to one of those shuttle PC's with VMWare ESXi The HDD seems to be the bottle neck right now (the light is almost always pure solid) right now I have a single 1TB Seagate 7200.11 connected by SATA. VMWare ESXi cannot detect it when running in AHCI mode, but does when running in IDE mode. I have read that IDE mode can give a 5% performance hit which might give me enough breathing room. However, I am open to setting up an external eSATA or some sort of raid to give me more than just the 5%. I am just weary of sinking some money into a bit of hardware without knowledge of whether it will work. Does anyone know of resources or procedures of how to get this working.

• Windows 7 security and Avast antivirus turned off by themself

  - by Simon Verbeke

  I was just browsing around when at once I got messages that UAC, windows defender, Avast, etc. got turned off, without me doing anything. Then my PC turned by itself. I'm now running virus scans and I checked my eventlogs, but found nothing yet. Windows Update also failed to install a new definition after I rebooted. Any idea what this could've been? EDIT: Forgot to mention that everything was turned on again after rebooting. I have since the reboot got nothing abnormal.

• Adding a W2008 Authenticating Server to existing W2003 Domain?

  - by spelk

  I have an existing W2003 Domain, simple setup with one DC and a SQL Server (approx 100 users). There are issues with Windows 7 Clients and login scripts and we're now seeing much greater numbers of Windows 7 users turning up as they upgrade their PC/Laptops. What I want to do, is add another Server with W2008 on it, and authenticate the Windows 7 Clients - but leave the W2003 server running as is - to prevent disruption to the network and the existing WinXP users. Is it possible? Any advice as to how do this, without major disruption to the W2003 network?

• IP not detected in terremark enteprise cloud server - how to install VMware on instance?

  - by JohnMerlino

  Using terremark enteprise cloud, when you create a server, you assigned an IP address to them and that IP is visible under Detected IP when selecting the server. However, I created a server, with IP address and I created an internet service and connected it with a node. I used protocol TCP and mapped it to port 3001. But I notice when I select my server, the IP address doesnt dsplay under Detected IP and then I VPN Connect, launch terminal and try to SSH with the IP to my server, and I get connection timed out. I presume the reason lies in that the IP address is not being detected. Someone suggested that my VMware-Tools is out of date and in fact on the server instance for VMware-Tools it does say "out of date". I'm not sure how to mount the instance and install VMware-Tools. I am using Mac OSX. Someone said that it will only work on PC running IE.

• Folder is not accessable, owner is not changeable. What should I do?

  - by Martin

  I'm facing currently a problem with a folder in windows 7, that is not accessable. Such a problem I had treated often in the last years on several pc's. But today the problem seems harder than the last times. In the past I get to grips with this by changing the folder owner and then modify the security settings. But this time it is not possible. If I want to set the owner, it says that I have no access for the change of owner. I already have tried to remove the folder by using the administrator-console, but this also print access restricted. What could I do. Do I have to start with PE and remove the folder? Are there alternatives?

• Permission denied on network share

  - by Philipp

  i have a Windows 8 host system running a virtual(hyper-v) Debian6 client with an lamp environment. My development environment runs under Windows and I mapped the folder with my php files to a network drive so Apache has access to them.(mount.cifs //pc/share /var/share/) This far no problems - I see my app on windows in the browser. The problem is, I can't write stuff in php to the share folder - everytime i got a permission denied message in my error logs. For testing purpose i tried to change the directory permissions of /var/share with chmod -R 777 /var/share without success. Now Iam a little bit stumped.. has anyone an idea how to solve this?

• VPN/Proxy server to bypass work proxy

  - by Trevor

  Here is my dilema, I am at work and can not set up a VPN connection to my VPN account in the USA. So what I would like to do is somehow have my "IE" at work connect to my home network and route any internet requests through my home PC to my VPN account, so I can access my USA Contents? So what I was thinking and I am not sure if this will work, but set up a proxy server at home on my home computer, that then routes all requests to my VPN Tunnel to the USA. Have my work computer use my home computer as the proxy and viola I have unrestricted internet access? Does that sound feasable? Thanks.

• why are CPUs so much more expensive in the UK than US?

  - by Nick Fortescue

  I'm looking at building my own PC. An Intel Core i7 960 3.2 Ghz is about £457 in the UK at various online retailers. In the US the price at newegg is $570 (this is about £380 at current exchange rates). 2 questions. 1) Why the difference (about 20%)? All I can think of is sales tax. 2) Am I right in assuming this is just a commodity part - if I ordered one from the US there is no reason it would be any different from one bought in the UK?

• Proxy Server suggestions

  - by Jon Menefee

  Here is the question I have that hopefully is not too general of a question. I have a network with approximately 25 PC's, 3 servers and 25 IP cameras. I have a firewall already on the network and it works fine for what I need, but my client is asking me if there is a way to put a Proxy server on the network to monitor where his employees are going when they surf the Internet. He is not wanting to block them (at least not thru the Proxy server), but he wants to make sure that they arent going to sites that would compromise the networked PCs. I have looked at TMG and it is a little more than what I want. I hesitate adding another firewall to the system because of the security cameras that are presently on the network (IP Cameras). I just want to put a policy in AD that would make certain Users (or Computers) use a Proxy server. Any suggestions on a good proxy server are welcome. Thank you

• What DNS server to use for dynamic load-balancing of website?

  - by Marki555

  I will have 2 servers in different datacenters (different countries) and I want to use DNS load-balancing mainly for High Availability of website hosted on those 2 servers. It is just ad tracking site, which records hit in local database and returns few lines on html code. I want to return 2 A records each time because of DNS pinning in browsers (if one server fails, browser will try second A record which it has already cached). Both servers will be acting also as DNS servers for redundancy. Now comes my proposed solution: I will use BIND and have both servers as a master for that zone. On each server there will be running script, which will periodically test availability (http) of both servers and remove IP from DNS in case of failure. Now the questions :) 1) Is BIND suitable for this solution? I think BIND performance is good and it is easy to manipulate the zone file via script. And as I will modify the zone only in case of failure/maintenance, the modifications (and thus bind reload) won't be often. 2) I plan to use TTL of 5 minutes. The website will have about 1000-3000 req/s but from distinct clients (each IP only 1-3 requests), so I think the DNS load won't be too much. I suppose their ISPs will cache the responses for those 5 mins. Is there any reason to lower the TTL even more? 3) Is my master-master approach good? Or should I make one of the servers master and the other one slave? Right now each server can monitor both itself and the other one. If only webservice fails, both DNS nodes will notice it. If the whole server fails, then the remaining DNS node will notice it and the failed node will not answer DNS queries anyway. 4) Is it a big issue when one NS server does not respond to queries? If yes, I can make a third DNS, so anytime at least 2 of them would accept queries... 5) Should I rewrite the zone file via script, or just use dynamic DNS update (for example via nsupdateutility)?

• Access Configuration Page of Modem (in bridge mode) through router

  - by Ujjwal Singh

  Given the Network Configuration: Internet (121.243.x.y/27) | (121.243.x.z) Static : Public Global IP Modem Bridge Mode | WiMAX (192.168.1.1/24) +169.254.1.1/24 : Modem Configuration Page | (192.168.1.2) Router DLink DIR 615 | Ethernet + WiFi (192.168.0.1/24) | Local network (192.168.0.2) Workstation Ethernet | no WiFi Is there any way, maybe using Routing Tables, to access the Modem configuration page at 169.254.1.1 from my local network, using a Windows 7 PC? Note that the modem is currently able to display its configuration page at 169.254.1.1, i.e. even while it is in bridge mode.

• Is it possible to run a "Windows Server 2008 R2 SP1 Hyper-V Virtual Machine" on Windows 7x64 Pro machine?

  - by tbone

  Specifically, I want to run this: http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=27417 This download contains a three Windows Server 2008 R2 SP1 Hyper-V Virtual Machine set for evaluating and demonstrating Office 2010, SharePoint 2010 and Project Server 2010. System requirements Supported operating systems: Windows Server 2008 R2 Additionally you will need: •Windows Server 2008 R2 (SP1 recommended) with the Hyper-V role enabled. •Drive Formatting: NTFS •Processor: Intel VT or AMD-V capable •RAM: 8 GB or more recommended •Hard disk space required for install: 100 GB ------------------------- So, the above text seems to indicate that you need a physical Windows 2008 Server (r2) server running, but from the googling I've done on the subject I've yet to come across a discussion that definitively answers the question. Many posts I've read seem to indicate it might be possible to run it on Windows 7 using one of the following: VirtualBox, Windows Virtual PC, VMWare but I'm not entirely sure.

• Linux foxboard network monitor

  - by het.oosten

  I want to use a Foxboard a simple network monitor for multiple routers (all routers are connected to the internet). Foxboard is a mini pc with an embedded version of Debian. My idea is to use multiple virtual network devices like this: eth0 192.168.2.10 eth0:1 192.168.3.10 eth0:2 192.168.4.10 I found a nice Python script to ping an external host here (the solution from Ryan Cox): http://stackoverflow.com/questions/316866/ping-a-site-in-python Is it possible to configure Debian to use eth0 when I ping www.site-a.com and eth0:1 when I ping www.site-b.com?

• What program can I use to make animated videos with Mac?

  - by cwd

  I've seen a lot of these cool info-diagram style voice-over videos like this one for Google Plus One: http://www.youtube.com/watch?v=OAyUNI3_V2c&feature=player_embedded What types of tools are required to make something like that? Related to that, what programs are good for creating and editing screen casts on Mac? I am only familiar with Camtasia, maybe snapxpro (and Jing, which I think may only be for PC). I would mostly like to create a video like the one above, but if I could add in a few seconds of a screen-cast that would be nice.

• Daemon Tools error (0xc0000006)

  I tried to reinstall Windows XP to Windows 7, but I could not install the video card drivers because the driver installation software only works on XP.I have launched the setup program with XP mode. After I installed the setup, I restarted the computer and Windows 7 wasn't booting.But that isn't the problem why I asked this question. The problem is that I have reinstalled my Windows 7 Ultimate to Windows XP SP3 and I wanted to install Dameon Tools.After installation I restarted the PC (as the setup wanted) and when the Daemon Tools launches it shows the error: Application failed to initialize properly (0xc0000006). Click OK to terminate the application.
