• Safely remove external USB drive fails due to $extend

  - by moontear

  When connecting an external USB 3.0 hard drive to my USB 3.0 ports I can never safely remove it. Somehow windows always keeps the journal files open: "Always" as in this time I only connected the drive, copied a 10GB VM and wanted to disconnect it afterwards (like 15 minutes after copying, so all copying was done). As you can see there is no other program keeping a handle on the disk besides System. I tried restarting explorer.exe as well as RemoveDrive.exe from Uwe Sieber. No luck, the locks on the hard drive always remain. My only solution is just unplugging it (whereas I'm afraid of damaging the data?) or restarting the computer (always helps, doesn't it?). Might it have something to do with me only having a SSD hard drive and the external disk is a regular drive? Might it have something to do with the USB 3.0 drivers (NEC Electronics USB Hub)? I never have this problem when using the regular USB 2.0 ports. Any ideas on how to properly unmount the disk?

• Ubuntu hard disk getting SATA errors

  - by Henadzy

  I am getting "UNC" errors on a hard disk on Ubuntu 9.10. It slows down my system, applications have not been responding for a long time. But when I mount the filesystem on another computer, it works properly. disk: SAMSUNG HD161HJ (SATA) syslog: Apr 25 00:28:25 vare6gin kernel: [ 885.773839] ata3.00: exception Emask 0x1 SAct 0x1e SErr 0x0 action 0x6 frozen Apr 25 00:28:25 vare6gin kernel: [ 885.773845] ata3.00: Ata error. fis:0x21 Apr 25 00:28:25 vare6gin kernel: [ 885.773861] ata3.00: cmd 60/08:08:3f:00:ad/00:00:10:00:00/40 tag 1 ncq 4096 in Apr 25 00:28:25 vare6gin kernel: [ 885.773864] res 51/40:24:67:c8:91/40:00:05:00:00/40 Emask 0x9 (media error) Apr 25 00:28:25 vare6gin kernel: [ 885.773871] ata3.00: status: { DRDY ERR } Apr 25 00:28:25 vare6gin kernel: [ 885.773877] ata3.00: error: { UNC } [...snip 3 similar repeats of last 4 lines; see revision history for full log...] Apr 25 00:28:25 vare6gin kernel: [ 885.773970] ata3: hard resetting link Apr 25 00:28:25 vare6gin kernel: [ 885.773974] ata3: nv: skipping hardreset on occupied port Apr 25 00:28:25 vare6gin kernel: [ 886.240073] ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Apr 25 00:28:25 vare6gin kernel: [ 886.256277] ata3.00: configured for UDMA/133 Apr 25 00:28:25 vare6gin kernel: [ 886.256305] ata3: EH complete Apr 25 00:28:27 vare6gin kernel: [ 888.176088] ata3: EH in SWNCQ mode,QC:qc_active 0xF sactive 0xF Apr 25 00:28:27 vare6gin kernel: [ 888.176099] ata3: SWNCQ:qc_active 0xF defer_bits 0x0 last_issue_tag 0x3 Apr 25 00:28:27 vare6gin kernel: [ 888.176102] dhfis 0xF dmafis 0x1 sdbfis 0x0 Apr 25 00:28:27 vare6gin kernel: [ 888.176109] ata3: ATA_REG 0x51 ERR_REG 0x40 Apr 25 00:28:27 vare6gin kernel: [ 888.176113] ata3: tag : dhfis dmafis sdbfis sacitve Apr 25 00:28:27 vare6gin kernel: [ 888.176120] ata3: tag 0x0: 1 1 0 1 Apr 25 00:28:27 vare6gin kernel: [ 888.176126] ata3: tag 0x1: 1 0 0 1 Apr 25 00:28:27 vare6gin kernel: [ 888.176131] ata3: tag 0x2: 1 0 0 1 Apr 25 00:28:27 vare6gin kernel: [ 888.176136] ata3: tag 0x3: 1 0 0 1

• How do I access my samba drive through several layers of network topology?

  - by stephenmm

  I have a new windows 7 Home Premium machine that is in a different room than my main computer area. As such I have to use a bridge and another router. Everything is working wonderfully except I cannot access the SAMBA drive with the new machine. I know that SAMBA is accessible as an older WinXP machine can access it. A picture of my network would probably be helpfull: To ISP | | +---------------------------+ | WAN | | Cable Modem | | (2WIRE678) | | | | | +---------------------------+ | +---------------------------+ | | (|) (|) +-----------+ | Belkin Router | | | | Wireless | | (F5D) |--+ +--| WinXP | | | |SAMBA USER | | | +-----------+ +---------------------------+ | | | | +------------+ | | Ubuntu | | | Apache + | | |SAMBA Server| | +------------+ | | +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ # # +---------------------------+ | | | Netgear Bridge | | (XET1001) | | | +---------------------------+ | +---------------------------+ | | | D-Link Router | | (DI-524) | | | | | +---------------------------+ | | | | +-----------+ | | | Win7 | |SAMBA USER?| +-----------+ More interesting data points: 1. I can ping the SAMBA server from the Win7 machine locally (Ie. 192.168.2.2) 2. I can access the webserver from the Win7 machine locally (Ie. 192.168.2.2) 3. I followed the advice to get Win7 and SAMBA to play nice: http://www.tannerwilliamson.com/2009/09/windows-7-seven-network-file-sharing-fix-samba-smb/ Sorry for being so long winded but it is kind of complex and I am really at a loss as to how to fix it. If any of you have some suggestions I would love to hear it!

• What is the proper way of debugging a slow Windows installation?

  - by Niklas

  You know the drill - you've been asked to check why you cousin's computer is running slow. I was there yesterday. Being a Mac user since 2007 I haven't really dug deep in Windows internals in the past five years. Googling for answers reveals many, many different answers: broken registry, spyware, antivirus program, fragmented disk, turning of visual effects etc. In this particular case I was asked to look at a two year old HP laptop with Vista. Windows was running incredibly slow and even opening up a new explorer window took almost a minute. I ended up doing everything of the above: running cc cleaner, defragmenting the disk, turning off visual effects, turning off norton and a bunch of other things people believe have an impact on Windows performance. Now I'd like to understand this in depth. Is there a proper, "scientific" if you so will, way of debugging and understanding where the problem with a slow running Windows installation lies? (In my particular case this concerned Windows Vista but let's try to create general guide for XP and Windows 7 too). To me, it seems wrong to just run a bunch of different tools without understanding the underlying cause of the error.

• BIOS not detecting working SATA hard drive.

  - by Evan

  Some time ago my power supply died. It's a long story from then till now, but the important bit is that I ended up with a new hard drive and a new power supply. I tested to see if my original hard drive was still alive, and it booted and worked perfectly until I turned it off. When I started it again it would not boot. I bought new SATA cables, assuming that the one I had was not seating properly (it was cheap and wobbly), but no dice. Upon start-up I am presented with a message telling me to insert boot media into the selected drive or add a drive and restart. Neither the new or the old drive is detected by BIOS, my Vista install disk, or from my bootable Linux USB drive. When I remove all of the RAM the computer ceases outputting visual information, and upon reinstalling the ram and starting up again gives me a "failed overclock" error. So, does anyone have an idea as to what might be going on? I'm completely lost at this point.

• Is this normal or does my AVG anitivirus have a virus? [closed]

  - by user390480

  Possible Duplicate: Computer is infected by a virus or a malware, what do I do now? [Note: This is not a duplicate and should not be closed as a duplicate as this is nothing like the other question. I am not asking if I have a virus, nor am I asking "what do I do now". I know that I have a virus and I know what to do. However, I am asking if these are normal AVG ads or if it has been taken over.] My Windows XP PC started acting strange and I am right now actually in Linux running off of a USB drive. I am running Avast under Linux and it has discovered some viruses on my XP drive. Some of the strange things happening in XP were: I could not get to Google.com My Hosts file was set to hidden and read only My Hosts file had an entry of ::1 And AVG had ads in it I've never seen before. Maybe it is normal but I Binged for AVG anti-virus and become.com but found no information. (The red lines and question mark are by me) Any thoughts?

• HP Photosmart C4780 printer/scanner breaks netgear WNDR3700v3 router on connection

  - by CodeJunkie

  A few months ago, we upgraded our Netgear router's firmware. Immediately, we started having trouble connecting to the internet. Each time this problem would happen, every device in the house would stop being able to make new connections to the internet. For example, you couldn't open new pages in the browser, but if Skype was running when the problem happened, you could keep talking to people. The only solution to this problem seemed to be resetting the router to factory defaults. Eventually, we solved this problem by just downgrading the router firmware. A while later, we got a new Netgear router. Almost right away, the new router started having exactly the same problems as the old one did on current firmware. The network connection would stay active and the computer would say it had an internet connection, but you couldn't do anything online except for using Skype. We eventually figured out that this happens every time our HP printer gets onto the network. Any time the printer gets onto the wireless network, the whole network stops connecting to the internet almost completely. The only thing that will fix it at that point is to reset the router to factory specs, and unplug the printer so it can't get back onto the network. The Netgear router has the latest version of the firmware, but the printer/scanner is very old. It looks to me like this problem is probably a result of a firmware conflict between the printer and the router, but I'm not sure how to fix that problem. Here's some additional information: Printer: HP Photosmart C4780 Router: WNDR3700v3 Router firmware: V1.0.0.22_1.0.17 (Stock, up to date firmware) Why would the printer getting on the network cause the router to not be able to access the internet correctly until it was reset? What can be done to allow the printer to be on the network without breaking the network for all other devices? Edit: One other thing that happens during this internet problem is that multiple computers in the house display an "IP conflict" message repeatedly, and extremely frequently (as often as every five to ten minutes, and every time a connection to the wireless is made).

• Strange Internet Connection issues

  - by Nodren

  I'm attempting to troubleshoot problems with a laptop computer(HP 8510w) while it's connected to a server of mine via Remote Desktop. I double checked all the settings on the win2k3 server for remote desktop to verify that remote desktop isn't what's causing the disconnect issues, and other people using different computers/laptops can all connect to remote desktop correctly with no issues. These problems happen specifically when the laptop is connected via wifi(several different wifi sources, so it's not an ISP issue) as well as connected via a Verizon data card. However there's no network downtime when the laptop is resting in the docking station and plugged into the network with the remote desktop server. These problems have also only recently occurred since a recent hard drive failure in which a new hard drive was purchased and the laptop had a fresh install of windows xp professional. There's no special software used on this machine, just office 2003. So my question is, what could cause two types of internet access to fail while other types do not? If it is infact related to the win2k3 server, why is this particular laptop getting disconnected when others are not and are all on at the same time?

• Virus on site but can't find where

  - by Rob

  WARNING! THIS IS ABOUT A VIRUS ON MY SITE. IT APPEARS IT HAS BEEN THERE FOR SOMETIME AND I'VE HAD NO PROBLEMS. BUT PLEASE BE CAREFUL. READ EVERYTHING I SAY AND SEE IF YOU CAN HELP ME WITHOUT VISITING THE LINK. AVG PICKS UP ON IT AND BLOCKS IT, MCAFEE DOES NOT. Sorry about the warning, obviously i'm not here to get anyone infected or anything like that. Basically I run the website sortitoutsi dot net. Ages ago I got a virus on my computer, they got hold of my FTP passwords and added some lines of javascript to the top of my site. I removed them and believe it was fixed. However i'm using the "Web Developer" extension for Firefox and chose to view all javascript on my page and find there are various links to horrible urls such as: gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/aboutus.org/aboutus.org/google.com/skycn.com/torrents.ru.php and gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/index.php?jl= These terms do not appear anywhere. In the source code, in any of the javascript or the css. I also can't see that there are any rogue images that I don't recognise either. So i've no idea where this javascript is coming from. Can anyone suggest how I can find references to these links and remove them? I can see them both in the Web Developer firefox extension and in the net tab using Firebug. Any help would be greatly appreciated

• Network connection keeps dropping - bad hardware?

  - by Bill Sambrone

  Hello all, I've into a bit of a wall with a client of mine. In an office of 20 people, he is the only one who experiences broken connections to his mapped network drives. I have everyone set up with about 6 mapped drives, all pointing to the same server (no DFS), and everyone else can access them lightning fast. The environment consists of a mix of Windows 7 and XP machines, all 32-bit. The server holding the data everyone is mapping to is running on Server 2008 R2, and is a domain controller. We recently swapped out their old 10/100 switch for a shiny new Dell PowerConnect gigabit switch. We have also replaced an old dying Sonicwall with a shiny new one. Everything is running on an ESX host except for the DC, where everyone is getting data from. In my client's office, we have done the following: Swapped out his computer (Win7 and XP box) Swapped out the desktop switch in his office Removed the desktop switch in his office Changed out the network cable going to the wall Ran 'net config server /autodisconnect:-1' on the server Disabled remote differential compression on his current Win7 box When we swapped out his network cable, everything seemed fine for about 4 days. Normally I would get a phone call a couple times per day letting me know that Outlook has crashed (there is a 9GB PST living on the server he is always connected to), or that his software he is running from his L drive has crashed. I almost thought I had this solved, but after we rebooted the DC the other night he all of a sudden couldn't stay connected to his mapped network drives for more than 10 minutes. When I ran 'net use' from the command prompt, it listed all the network drives where were randomly in a state of 'OK', 'Disconnected', or 'Reconnecting'. What else should I try? Maybe there is bad wiring in the wall, patch panel, or a bad port in the new switch I have in the server room?

• How I can fix the "Display Driver has stopped responding and has recovered"?

  - by Vitor Rangel

  I'm using a GeForce GTX 580, with Windows 7 64-bit. The driver version of the GTX is 301.42. The problem happens after a few minutes, when I'm playing specifc games. It won't happen in all games - And I don't have any idea why these games doesn't work. The games that doesn't work: Battlefield 3, Civilization V, Sniper Elite V2. The games that work: Mass Effect 3, Crysis 2, Team Fortress 2, Left 4 Dead 2, Skyrim, L.A. Noire. As you can see, it's not a problem of "The games that demand more stop working". I've tryed updating the driver of the graphics-card, the bios of the motherboard, even formated my computer (It was needing it) and instaled every driver in the last version possible. This problem happens since I bought my graphics-card, 6 months ago. After a few minutes, from 10 to 20, the pixels in the monitor become strange, with random colors and effects, like it was broken. Then, everything goes black, and the message appears "Display Driver has stopped responding and has recovered". After that, I need to close the game and start again. I am not overclocking, and my temperature never goes higher than 70ºC.

• keyboard intermittently stops working, even after reinstalling windows 7; possibly a Chrome issue?

  - by neverskipbreakfast

  My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash a couple of the ctrl+alt+windows type keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu, but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) *Unplugging & reconnecting keyboard does NOT fix it. *Connecting a different keyboard does NOT fix it. That one won't work, either. *Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. *Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears, they keyboard won't work, and neither will the icon to pull up the on-screen keyboard. Otherwise my mouse can click around just fine. I can only log onto a non-password protected account. *Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. *Clearing my Chrome browsing data stopped the problem from recurring for a week or so. *I use Avira free antivirus software, and repeated scans turn up nothing fishy. *I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. The only thing I suspect is something in Google Chrome -- I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?

• Has anyone had luck running 802.1x over ethernet using the stock Windows or other free supplicant?

  - by maxxpower

  I just wanted to see if anyone else has had luck implementing 802.1x over ethernet. So here's my basic setup. Switch sends out 3 eapol messages spaced out 5 seconds apart. if there's no response the machine gets put on a guest vlan with restricted access. If the machine is properly configured it will authenticate and be placed into a secure vlan. About 10% of my windows xp users are getting self assigned 169 addresses. I've used the Odyssey Access Client and it worked without a hitch. I'm using the setting to automatically use the users windows login to authenticate, but it's workign on 90% of the machines so I don't think that's the issue. Checking the logs on the dc it seems that the machines are trying to authenticate with computer credentials even though they are configured not to. I'm running Juniper switches with IAS for radius. I have radius configured for PEAP and MSvhapv2. Macs and linux boxes seem to have no issues authenticating. One last thing to add If I unplugging the ethernet cable and plug it back in usually resolves the issue, but I'd hardly call that acceptable for production. Kinda long winded and specific for a discussion, but just want to see if anyone else has had similar issues or experiences, or if anyone knows of a free XP supplicant that actually works with 802.1x over ethernet.

• plesk: how to configure reverse proxy rules properly?

  - by rvdb

  I'm trying to configure reverse proxy rules in vhost.conf. I have Apache-2.2.8 on Ubuntu-8.04, monitored by Plesk-10.4.4. What I'm trying to achieve is defining a reverse proxy rule that defers all traffic to -say- http://mydomain/tomcat/ to the Tomcat server running on port 8080. I have mod_rewrite and mod_proxy loaded in Apache. As far as I understand mod_proxy docs, entering following rules in /var/www/vhosts/mydomain/conf/vhost.conf should work: <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests off RewriteRule ^/tomcat/(.*)$ http://mydomain:8080/$1 [P] Yet, I am getting a HTTP 500: internal server error when requesting above URL. (Note: I decided to use a rewrite rule in order to at least get some information logged.) I have made mod_rewrite log extensively, and find following entries in the logs [note: due to a limitation of max. 2 URLs in posts of new users, I have modified all following URLs so that they only contain 1 slash after http:. In case you're suspecting typos: this was done on purpose): 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) init rewrite engine with requested uri /tomcat/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (3) applying pattern '^/tomcat/(.*)$' to uri '/tomcat/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) rewrite '/tomcat/testApp/' - 'http:/mydomain:8080/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) forcing proxy-throughput with http:/mydomain:8080/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (1) go-ahead with proxy request proxy:http:/mydomain:8080/testApp/ [OK] This suggests that the rewrite and proxy part is processed ok; still the proxied request produces a 500 error. Yet: Addressing the testApp directly via http:/mydomain:8080/testApp does work. The same setup does work on my local computer. Is there something else (Plesk-related, perhaps?) I should configure? Many thanks for any pointers! Ron

• Can I connect a Playstation 3's HDMI output to my monitor's DVI-D input? [migrated]

  - by HankJDoomstorm

  I'm attempting to connect my Playstation 3 to my computer monitor. The monitor has a DVI-D (dual link) input, so before distinguishing between the different DVI varieties, I bought a DVI-I (dual link) to HDMI converter that won't fit into the port on the monitor (not only that, there isn't enough physical space in the back of the monitor to fit that much stuff before it hits the bottom of it). So I grabbed a DVI-D (single link) cable and got a female-to-female DVI-I coupler, and plugged the DVI-D cable into the monitor and the whole mess of converters. The end result was HDMI to DVI-D single link, but my monitor isn't receiving a signal on its digital channel. (For clarity's sake: DVI-D DL input on Monitor, DVI-D SL cable, DVI-I DL female-to-female coupler, DVI-I DL to HDMI converter, HDMI output on PS3) I don't know much about this stuff (obviously), but my educated guess is that the bandwidth of the PS3 is too high for the DVI-D Single Link cable, so nothing's getting through. Will replacing the single link cable with dual link resolve this? If not, is it possible at all? Oh, I should mention I'm aware I won't get audio through the monitor. I have an RCA to 3.5mm converter for that.

• Windows 7 caches FTP credentials?

  - by Martin Booka Weser

  On my remote maschine i have an iis 7.5 (win server 2008) and set up an ftp site with iis manager authentication. I then did active directory user isolation and isolated my users to physical folders according to their names. So far, so good. I can access with ftp cliens from everywhere with different test accounts that i previously set up in the iis manager auth. Every user connects to its own folder. When i now tested with windows 7 as a client i did the following. Explorer - computer - right click - add network address - the ip of my remote maschine - user1 - password1 Perfect - it works. I now want to connect with user2. So I deleted this network address and set up a new connection, but with user2 (or even anonymous) instead. Now the strange thing: Windows doesn't even ask me for a password again. It just connects me to the folder of the user1. I already disabled ftp caching in the IIS and i disabled the user1 account in IIS manager authentication! Still, if i set up a network connection with this windows 7 it connects to the folder user1 . No matter which username i use (anonymous, administrator, user2,...). And if i connect with other ftp clients or other computers it all works perfectly. So I assume that this one windows somehow caches the credentials... But then, why does the IIS still accepts this credentials even if i disabled this user1 account??? Thanks.

• Motherboard Dying? AHCI Drive Init and boot loop intermittent failure

  - by Adam Heath

  My computer is now intermittently failing to boot up. For the last couple of days, when I turn it on it hangs on "AHCI Drive Init...", and when powered off and on again, it booted up fine. Today, it did the same but failed in a few other ways too, seemingly at random: Hangs on "AHCI Drive Init..." Boot loop (after "AHCI Drive Init..." appears for a split second (no drives listed)) Black screen (after "AHCI Drive Init..." appears for a split second, a black screen with all fans still running) The interesting part is that the above is not affected by what drives are connected, or what to. I have tried both disks, each disk individually and no disks (along with trying the primary and secondary SATA controllers), none of this has any effect on what happens. After about 20+ attempts of different combinations, it suddenly decided it would boot up into Windows, and I hadn't touched anything for about 2 cycles. Motherboard: Gigabyte GA-870A-USB3 Processor: Amd Phoenom II x6 1090T RAM: 8GB Corsair 1600 Primary Disk: Plextor 128GB SSD Secondary Disk: Western Digital Black 1TB OS: Windows 8.1 Is this my motherboard dying? Or could something else be the cause? Thanks!

• What could cause these "failed to authenticate" logs other than failed login attempts (OSX)?

  - by Tom

  I've found this in the Console logs: 10/03/10 3:53:58 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:53:58 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). 10/03/10 3:54:00 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:54:00 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). 10/03/10 3:54:03 PM SecurityAgent[156] User info context values set for tom 10/03/10 3:54:03 PM authorizationhost[154] Failed to authenticate user (tDirStatus: -14090). There are about 11 of these "failed to authenticate" messages logged in quick succession. It looks to me like someone is sitting there trying to guess the password. However, when I tried to replicate this I get the same log messages except that this extra message appears after five attempts: 13/03/10 1:18:48 PM DirectoryService[11] Failed Authentication return is being delayed due to over five recent auth failures for username: tom. I don't want to accuse someone of trying to break into an account without being sure that they were actually trying to break in. My question is this: is it almost definitely someone guessing a password, or could the 11 "failed to authenticate" messages be caused by something else? EDIT: The actual user wasn't logged in, or using a computer at the time of the log in attempts.

• Why am I seeing Zero errors in non-ECC RAM?

  - by Alexander Shcheblikin

  According to sources, memory errors are a very probable event: Some say the probability of a DRAM error is 95% in just 3 days of operation of a computer with just 4 GB of RAM, others say 32% of servers experience at least one error in a month with 8% of DIMMs being at fault. Contrary to those horrors, in my more than 10 years of personal computers use I have seen exactly none of the memory errors. I admit I never paid special attention to the subject. However, I have ventured multi-hour memtest86 runs couple of times and never seen an error either. Some of the factors that IMO should aggravate the memory problems: I build my computers out of the most "bulk commodity" parts: mainstream budget motherboards and the next to cheapest memory. also I usually max out the technology available, e.g. in the times of 32 bit OS'es I used 4 GB of RAM and with the current desktop CPUs and the newer 64 bit OS'es I use 32 GB of RAM. memory usage is moderately heavy with lots of virtual machines up running small and big tasks 24/7/365. But nevertheless, no memory-related problems ever found! How's that?

• Why is dwm.exe using so much memory?

  - by Leonard Challis

  I've scoured the web, but I'm sick of reading "scan your computer for viruses" and "upgrade your RAM" on answers to similar questions to this. I understand that dwm.exe is for (simply put) caching bitmaps for things like Aero-peek and similar, but as far as I have read it shouldn't be using vast amounts of memory. My colleague and I both have 4GB of RAM, Core 2 Duo, blah, blah -- essentially they're pretty capable. His dwm.exe is running at around 30mb, mind is currently running at about half a gig, though it does fluctuate quite a lot. This is the same while running the exact same applications (currently Zend studio, FireFox (with firemin - low memory usage), Outlook). Every so often I will get a notification asking me if I want to switch to Aero Basic because it's using too much memory, and sometimes it will just switch itself to basic and let me know why. I know it's possible to stop it switching, but I want to know why it is using too much memory otherwise it's just papering over the cracks. One thing to add is this seems to have started after a robbery on Monday, where two of my monitors were stolen, and I had to temporarily use a couple of alternative monitors. I am now using brand new monitors but the problem is the same. All drivers installed and working seemingly fine. Any ideas why the usage is so high? We are using windows 7 64-bit Professional.

• RouterLess, house-wired network using multiple powerline adapters

  - by Cliff Arnell

  related to the 'old days' of one ethernet cable tapped with Ts for each monitor.... my question might be very simple... or not. I have an over-the-air internet provider with a wire dish with a powered transceiver and cat5 cable out of the providers supplied modem. I'm presently connecting the output of the modem into my wireless router which sends the internet signal all over the house. Standard stuff, I believe. My Question. Can I just connect the output of the modem into 1 powerline adapter and tie all my equipment such as computer, printer, laptop, Tivo recorder, etc. into 1-each local powerline adapters located near each devices resulting in a 'house-wired' network and no router? I'm bothered by the idea that my over-the-air provider might be using something in my router to establish and keep my IP connection alive. I did have to configure the router for my IP, a router which, in my proposed scenario, would no longer exist. Thank you for your help.

• Group Policy for DNS Server Addresses

  - by John

  This question deals strictly with the methodology of using Active Directory to publish DNS settings and controlling the DNS server address order to domain attached clients. This is not asking about if this is the right function, role, or best use of group policy; but rather, how to make it work. I would like to be able to publish in group policy DNS addresses and possibly control the order in which the client consumes the addresses. I have tried following the information from this site without success. I set the following setting within group policy, but the client never shows the settings within the TCP/IP properties. Computer Configuration/Administrative Templates/Network/DNS Client/DNS Servers I did list them as a single space separated list. For example, the following: 192.168.0.1 192.168.10.3 192.168.34.2 192.168.2.67 192.168.56.99 192.168.99.23 This would be for Windows 7, Windows Server 2003, and Windows Server 2008 clients. I am not sure what I am doing wrong or how to get this to work. Am I missing a setting? Do I need to set something differently?

• Best console based text editor not only for programmers [closed]

  - by robo

  I need console based text editor for writing both source codes and human readable texts such as emails. I need it to be user friendly. It mean for me: You can use it the same way as the notepad or gedit. You can use mouse there. If you need your mother of girlfriend or somebody to edit your text they will know what to do, they will not realize it is a console and will have only a feeling it is something like a notepad. copy, paste, undo works as usual with usual key combinations (Ctrl-C, Ctrl-V, Ctrl-Z). shift and arrows works as usual. They select the text. And when I return to the computer I want to use the text editor for programming. I expect: Syntax highliting auto indenting replacing spaces with tabs keyboard shortcuts for compiling possibility to configure it to use a debugger autocompletions for c#, java, c++ and other languages other things I expect from IDE's. I was working and configuring vim for a few years. But It never fulfilled all of my expectations (but it almost did). I thing I could get vim configured perfectly if I had few more weeks time for configurating it. Unfortunately I cannot afford to be configuring vim forever. Is there other alternative? Hopefully some editor I once set up and it will works forever? What do you use? I often hear people are using emacs. Is it worth learning?

• Switching from Onboard intel to Nvidia Dedicated GPU

  - by Anarkie

  How can I switch from Intel onboard grpahics to Nvidia Dedicated GPU? When I go to windows screen resolution I see intel. I cant change it. I go to Device Manager, I see both Adapters are there and Nvidia is known.I disabled intel, I didnt see any option to set one as primary so I disabled intel, black screen!Reboot and re-enable intel. I right click on the desktop, choose "Nvidia Control Panel" and on 3D options I chose the desired game I want to play, High performance Nvidia, but it didnt switch when I started the game. Then I made preferred GPU in the global settings High performance Nvidia for everything it still didnt change.I understand to save the battery etc. there is a switch option between these two but I dont see this switch when it is necessary, I cant also switch manually?Is there a manual switch FN key?I looked but couldnt find. Why I want to do this? 1) Better game peformance. 2) I want to play an old game from 2002(Diablo 2 LOD), when I start the game there are black bars on the sides, so screen becomes just smaller which I dislike!I heard this is intel's specification to center the display.But instead I would like to scale or expand it to fit widescreen(fullscreen).Which should be possible with Nvidia. My Notebook Specs: Fujitsu Lifebook AH531, Win7 , 64 bit, i5, intel HD graphics onboard, Nvidia GT 525. I didnt install Nvidia later, it was always installed and ready from the moment I turned on the computer first time. How I determined that the cards werent switched when I am playing the game: with the windows key I exited from the game, then looked at screen resolutions menu, still saw intel, also the game was still with black bars.I know intel GPU should enough for Diablo 2 but I am interested in this answer for further games, I dont always play Diablo, what if I install an up to date game for example?Then Intel will not be sufficient.I would like to learn the switch option.
