• 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?

• RRAS Problem routing to central site from RRAS server only?

  - by TomTom

  Given is an office connected to headquarters using a RRAS bridge (2 virtual machines using RRAS to route between the two networks). Naming: The office is A, the RRAS on A is a-lnk. THe headquartters is B, b-lnk the RRAS machine there. The VPN works perfectly - machines can ping and work between the sites. Domain controllers on both ends replicating, DFS working, remote desktop working. All in all... everything is fine. EXCEPT: a-lnk itself can not reach any machine in B. This would normally not be troublesome (noone ever does anything on a-lnk), but there are two exceptions: * a-lnk is supposed to get it's license from a KMS in B, so not being able to reach B means it is not prolonging. * a-lnk is supposed to pull updates from a WSUS in B - and not being able to reach B means - no updates. Given that thigns work (and security is a minor issue - A-lnk is not reachable from the internet as it is behing a NAT hardware anyway) this got not handled for months. I just wan to get this item ticked off now. Anyone an idea what this is? It definitely is not a "dns does not work" or "routing in general is bad" item, as any computer in A can connect to any computer in B, and the other way arount - only the RRAS computer itself seems to do something really awkward. Platform for both: 2008 R2 standard.

• Want to use something like Citrix XenDesktop, Free Alternative?

  - by Chris

  I'm looking to go into IT, general office server management, and it looks like XenDesktop would be a awesome tool to use. If I get it right, you would store a central image of the OS you want to deploy (in an iso file) on the main server. Then use XenDesktop to pull that image down to the client, and it will then boot the OS inside of the virtual machine. Does it download the image of the OS and store it locally (like cloning the VM onto the client?) I'd love to find a free (possibly open source?) alternative to this, I keep on hearing about KVM in Linux and PXE booting a minimalistic OS to use remote KVMs.... Would that be what I'm looking for? Ideally, I'd like a system.. - That allows me to manage one central image for multiple clients (virtualized hardware) - Easily boot a thin client OS that connected to XenDesktop. Would those things be possible with some kind of free alternative? Some guidance would be greatly appreciated.

• 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?

• Production monitoring for EC2 instances

  - by Janine

  I'm setting up my first production instance on EC2 and want to make sure I have all necessary monitoring in place. There are three different types of things I want to monitor: Is the instance running? EC2 instances can be terminated without warning if the underlying hardware fails, and as far as I know they aren't automatically restarted. So if not, start it back up. Is UNIX running properly? This is the usual stuff about CPU load, disk space, etc. Is the website responding? If not, restart it. I initially set up Nagios on a physical server outside the cloud, but it is really only helpful for item 2. It can tell me if the instance is gone or if the website is not responding, but as far as I can tell it can't execute any commands to fix the situation. My Googling on this subject has yielded a plethora of options - Cacti, Monit, God, Ganglia, and probably more I'm forgetting now. I don't have time to research them all. I am aware of Amazon's Cloudwatch but it doesn't seem to do anything that my Nagios installation doesn't already do. If you already have something like this in place, can you please share what has worked well for you?

• How do I stop VLC from stealing my volume buttons

  - by MGOwen

  when I press the volume buttons on my laptop, usually the system volume is changed. However, when I do this with VLC it "steals" the presses and adjusts it's own "volume" instead. The system volume is also changed. I can't find any way to turn this off in VLC. Does anyone know? Update: Sorry, some more details I should have included originally: VLC VERSION: 1.1.4 (and a few previous releases, back to about 1.1.0 or so, I think) OS: Win Vista Pro 32 HARDWARE: Dell 1720 laptop (the volume buttons are little buttons on the front of the unit, they may work something like "media" keyboard volume buttons) Update: The buttons seem to map to Ctrl+Alt+b and Ctrl+Alt+c (according to the shortcut key box in windows shortcut properties) but the VLC advanced preferences hotkeys screen doesn't list these as the keys it uses for volume. I changed it so there are no volume hotkeys in VLC settings - no luck it still steals the presses and adjusts the volume. Also, pressing Ctrl+Alt+b or c doesn't change my system volume, so who knows what windows or VLC are doing to recognise those volume buttons. :(

• 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?

• 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. Radeon 6950 (MSI Frozr II), Seasonic X 560, Core i5 2500K at stock clockspeeds, 16GB RAM, Asus P8P67 M Pro

• 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

• Can't create new Volume on Unallocated Space

  - by natediggs

  I installed Windows Server 2008 R2 on a Dell server that has one volume that is a 6 TB RAID 5 array. I created a 120GB install volume and I'm now trying to create a 5 TB data volume. For what ever reason Windows will not allow me to create a new volume out of all of the unalocated space. Windows will allow me to create a new volume out of one 2TB block of unallocated space but not the remaining 3.5 TB block. Tried to post a screen shot but I was blocked. If I right click on the 1949.85 GB block of space there is the option to create a new volume. If I click on the 3539.5 GB block of space that option is grayed out. If I go into diskpart and try to create a new partition, diskpart says that there is only 1949GBs free on the volume. I know this process works because I did the exact same thing on another server that we have that is the exact same hardware configuration on which I used the exact same Server 2008 R2 install image. Any help would be greatly appreciated. Nate

• MicroSD card getting corrupted for no good reason

  - by ChaosR

  I recently bought an MicroSD card online. It's a Sandisk 16GB class 2. However, it has a nasty problem. Every time I fill it with my data, the fat tables get corrupted. I've tried reformatting it, blanking it, doesn't seem to solve the problem. I have tried windows and linux (ubuntu), both have the problem. I've used my usb microsd readers, and even tried putting it in my phone and putting data on it from there. All have this problem. Now the really odd thing is, besides the corrupted file tables, no programs can find anything wrong with the hardware. I've tried both chkdisk and "badblocks -w", neither give any type of error. Now I don't know if the actual data gets corrupted, or if its just filesystem tables. What happens is that one or more folders start showing a load of chinese-charred (random UTF8 symbols I suppose) folders and files, and it is impossible to do anything with those. All the other data (outside of the corrupted folders) seems fine. I've tried to test it, and the problem doesn't seem to show up until I fill the disk upto about 3~4GB. After that I can still access the data. But as soon as I eject/safely remove/unmount it, the bad things happen somehow. Next time I plug it in, the folders I most recently wrote to (but sometimes also the folders I wrote the time before last time to) are all gibberish. Does anybody have any clue what might be going on here? EDIT: It seems I can't even put ext3 or ext4 on it, they both complain about a corrupted journal. Gheh, guess something is really broken here.

• 802.11g -> wired ethernet bridging not working

  - by Malachi

  Usually people want to go the other direction, but I want to take our relatively fast and stable house 802.11g signal and bridge it to ethernet. I have tried using an Airport Express (the b/g flavor) and my i7 MacBook pro, both to no avail. Word is that the b/g flavor of This flavor of Airport Express maxes at firmware 6.3 which doesn't support this kind of bridging properly. However, I expected my MacBook pro to do the job with its "Internet Sharing" feature. Alas, although my wired PC does sort of see it, it doesn't work out. Strangely, using DHCP the PC receives the same IP address as my MBP uses on the network. Less strangely, but still surprisingly, the wired ethernet port on my mac registers as the IP address of the gateway when queried with IFCONFIG. It sort of makes sense that the mac would "pretend" to be the gateway, but the whole thing just isn't working and seems configured wrong - but all the docs I see say basically "OS X Internet Sharing: click it and go". What do I do? Do i really have to buy more hardware, even though I have plenty of would-be candidates for bridging? Incidentally, the host router originating the 802.11g signal is a belkin 802.11g router, and is documented to support WDS.

• ssd firmware, linux: updating large batch of drives

  - by wryfi

  I was recently hit with a fatal firmware bug that affected dozens of Crucial SSDs deployed in my datacenter. Many of the affected machines use LSI or other proprietary SAS controllers, which Crucial's bootable ISO does not recognize. None of the affected machines has a Windows license. The story is roughly similar for other SSD mfrs, including Samsung and Intel. To resolve this issue, I was forced to stop each machine, remove the affected SSD, remove the SSD from its hotswap caddy, install it temporarily into my ThinkPad, flash the firmware, reverse, rinse, repeat. It took the better part of a day to get through all the affected devices. I am looking for hardware, software, and/or purchasing strategies to ease this pain, as SSD firmware bugs seem inevitable, and our SSD footprint is growing. My first thought is to get a laptop with eSATA and one of these cables (http://www.newegg.com/Product/Product.aspx?Item=N82E16812311004). That should at least make it so I don't have to remove the drives from their caddies. Surely others have run into this. Any novel solutions?

• Windows VPN for remote site connection drawbacks

  - by Damo

  I'm looking for some thoughts on a particular way of setting up a estate of machines. We have a requirement to install machines into unmanned, remote locations. These machines will auto login and perform tasks controlled from a central server. In order to manage patching, AV, updates etc I want these machines to be joined to a dedicated domain for this estate. Some of the locations will only have 3G connectivity (via other hardware), others will be located on customer premises in internal networks. The central server (of ours) and the Domain Controller will be on a public WAN. I see two ways of facilitating this. Install a router at each location and have a site to site VPN between the remove device and the data centre where the servers are location Have the remote machine dial up and authenticate via a Windows VPN connection to the DC via RAS Option one is more costly to setup and has a higher operational cost. It also offers better diagnostics if the remote PC goes down. Option two works well but is solely dependent on the VPN connection been made before any communication can be made to the remote machine. In a simple test, I can got a Windows 7 machine to dial a VPN prior to authentication to a domain, then automatically login to the machine using domain credentials. If the VPN connection drops, it redials. I can also create a timed task to auto connect every hour in case of other issues. I'd like to know, why (if at all) is operating a remote network of devices which are located in various out of band locations in this way a bad idea? Consider 300-400 remote machines all at different sites. I'd rather have 400 VPN connections to a 2008 server than 400 routers, however I'd like to know other opinions on this.

• 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.

• 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?

• Linux VLAN Bridge

  - by raspi

  I have home network with VLANs, one for LAN, one for WLAN and one for internet. I'd like to use bridging so that instead of configuring these same VLANs to every machine, they had own VLAN ID and bridges were LAN, WLAN and internet. I've tried it but for some reason keep-alive/ttl seems to get broken because SSH sessions etc suddenly disconnects. We have this same setup working in workplace for 4+ years with 100+ customers but it's custom firewall/router hardware so accessing it is impossible. I know that it runs Linux. So what is Debian/Ubuntu default network settings doing wrong or is it just NIC driver/hw problem? I've tried to mess araund with ttl etc settings without any luck. The bad stuff is happening in the bridge because current VLAN-only setup works fine. interfaces: auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 allow-hotplug eth1 iface eth0 inet static iface eth1 inet static auto vlan111 auto vlan222 auto vlan333 auto vlan444 auto br0 auto br1 auto br2 # LAN iface vlan111 inet static vlan_raw_device eth0 # WLAN iface vlan222 inet static vlan_raw_device eth0 # ADSL Modem iface vlan333 inet static vlan_raw_device eth1 # Internet iface vlan444 inet static vlan_raw_device eth0 # LAN bridge iface br0 inet static address 192.168.0.1 netmask 255.255.255.0 bridge_ports eth0.111 bridge_stp on # Internet bridge iface br1 inet static address x.x.x.x netmask x.x.x.x gateway x.x.x.x bridge_ports eth1.333 eth0.444 bridge_stp on post-up iptables -t nat -A POSTROUTING -o br1 -j MASQUERADE pre-down iptables -t nat -D POSTROUTING -o br1 -j MASQUERADE # WLAN bridge iface br2 inet static address 192.168.1.1 netmask 255.255.255.0 bridge_ports eth0.222 bridge_stp on Sysctl: net.ipv4.conf.default.forwarding=1

• Windows 7 64 bit Installation freezes after a while durig the setup

• Samsung laptop randomly shuts down

  I've rewritten this question because it turned into an indecipherable mess. I have a Samsung R560 laptop that is overheating, and shutting itself down under load consistantly. Thank you quickcel for reccomending me Speedfan to monitor my temps. Here they are (Load / Idle): (Ignore "Temp1 and Temp2", whatever sensors they are they'd always random, pretty sure they're broke). The load temperature is after just 5 minites of playing Fallout 3 - another 5 minutes and it (the GPU - 9600M GS) consistantly breaches the mid 90's then shuts down, so it's hard to get a good picture of it. I'm looking for some solution or way to decrease these temperatures, because they seem far too high even idle. I've tried: Opening up the case and clearing of all dust with compressed air. Updating drivers for my Graphics card Have purchased and am using a notebook cooler I don't want to: Undervolt / underclock (defeats the point of having a more expensive card) Use lower power / performance settings (again, i might as well have bought something cheaper) Is there anything else i can try (software or inexpensive hardware) that can help me fix this? Has anybody had a Samsung laptop and knows if this can be sorted under my warranty, and the turnaround time of sending it off (UK?)(it has always ran hotter than it should, but now at 6 months old is getting hot enough to power off)

• 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?

• 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. Radeon 6950 (MSI Frozr II), Seasonic X 560, Core i5 2500K at stock clockspeeds, 16GB RAM, Asus P8P67 M Pro

  - by Rogue

  Want to setup an intranet for a small business setup. Current Setup 28 computers running Windows ( few older pc's run Windows Xp but most run Windows 7) Spare Dell Pentium 3 which can run as a server. 6 switches spare NIC's and lots of lan cable available for networking. 3 Independent Internet connections Currently we have 3 independent networks which share internet connections, each network uses a different internet connection. Current network is setup solely to share the internet connection. What I need to achieve in this intranet Setup one common network. Instant file transfer via local network (maybe setup a file server?) Local text and voice messenger software Bridge the 3 internet connections and route all the internet connections from the main server Ability to allow or deny internet access to any computer on the network. Remote access from the main server to the client pc's on the network to debug software issues What operating system should I use on the main server? Do I need a hardware firewall? Any setup guides / resources or how-to's on how I can achieve the above requirements.
