• Adding new SPNs to existing service ids

  - by jmh

  We have a tomcat server using spring-security kerberos to authenticate users to the webpage against active directory. There are around 25 domain controllers. The site has two CNAME based DNS aliases. The site currently has one Service ID with SPNs registered for the DNS A record as well as each of the CNAMEs. While everything is working right now, I don't know how to reliably change this configuration without possible downtime. The reason is that clients cache kerberos tickets: http://www.juniper.net/techpubs/en_US/uac4.2/topics/concept/user-role-active-directory-about.html The 'kerbtray.exe' program is helpful for viewing and deleting Kerberos tickets on the endpoint. Old tickets must be purged from the endpoint if SPNs are updated or passwords are changed (assuming the endpoint still has a cached copy of the ticket from a prior SPNEGO request to the MAG Series device. During testing, you should purge tickets before each authentication request. Description of "klist" program used to inspect/delete cached tickets: http://technet.microsoft.com/en-us/library/hh134826.aspx So if each of the clients (users running windows) who connect to my web server have kerberos tickets that become invalid as soon as I update the SPNs or passwords, how do I ensure changes are seamless? Are there any operations that can be done safely? I can't just ask all of the users to install klist and delete their old tickets.

• Combining URL mapping and Access-Control-Allow-Origin: *

  - by ksangers

  I am in the progress of migrating an old banner system to a new one and in doing so I want to rewrite the old banner system's URL's to the new one. I load my banners via an AJAX request, and therefore I require the Access-Control-Allow-Origin to be set to *. I have the following VirtualHost configuration: <VirtualHost *:80> ServerAdmin [email protected] ServerName banner.studenten.net # we want to allow XMLHTTPRequests Header set Access-Control-Allow-Origin "*" RewriteEngine on RewriteMap bannersOldToNew txt:/home/user/banner.studenten.net/banner-studenten-net-to-ads-all4students-nl-map # check whether a zoneid exists in the query string RewriteCond %{QUERY_STRING} ^(.*)zoneid=([1-9][0-9]*)(.*) # make sure the requested banner has been mapped RewriteCond ${bannersOldToNew:%2|NOTFOUND} !=NOTFOUND # rewrite to ads.all4students.nl RewriteRule ^/ads/.* http://ads.all4students.nl/delivery/ajs.php?%1zoneid=${bannersOldToNew:%2}%3 [R] # else 404 or something ErrorLog ${APACHE_LOG_DIR}/banner.studenten.net-error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog ${APACHE_LOG_DIR}/banner.studenten.net-access.log combined </VirtualHost> My map file, /home/user/banner.studenten.net/banner-studenten-net-to-ads-all4students-nl-map, contains something like: # oldId newId 140 11 141 12 142 13 Based on the above configuration I was expecting the following: GET /ads/ajs.php?zoneid=140 HTTP/1.1 Host: banner.studenten.net HTTP/1.1 302 Found ... Access-Control-Allow-Origin: * Location: http://ads.all4students.nl/delivery/ajs.php?zoneid=11 But instead I get the following: GET /ads/ajs.php?zoneid=140 HTTP/1.1 Host: banner.studenten.net HTTP/1.1 302 Found ... Location: http://ads.all4students.nl/delivery/ajs.php?zoneid=11 Note the missing Access-Control-Allow-Origin header, this means the XMLHttpRequest is denied and the banner is not displayed. Any suggestions on how to fix this in Apache?

• Orphan IBM JVM process

  - by Nicholas Key

  Hi people, I have this issue about orphan IBM JVM process being created in the process tree: For example: C:\Program Files\IBM\WebSphere\AppServer\bin>wsadmin -lang jython -f "C:\Hello.py" Hello.py has the simple implementation: import time i = 0 while (1): i = i + 1 print "Hello World " + str(i) time.sleep(3.0) My machine has such JVM information: C:\Program Files\WebSphere\java\bin>java -verbose:sizes -version -Xmca32K RAM class segment increment -Xmco128K ROM class segment increment -Xmns0K initial new space size -Xmnx0K maximum new space size -Xms4M initial memory size -Xmos4M initial old space size -Xmox1624995K maximum old space size -Xmx1624995K memory maximum -Xmr16K remembered set size -Xlp4K large page size available large page sizes: 4K 4M -Xmso256K operating system thread stack size -Xiss2K java thread stack initial size -Xssi16K java thread stack increment -Xss256K java thread stack maximum size java version "1.6.0" Java(TM) SE Runtime Environment (build pwi3260sr6ifix-20091015_01(SR6+152211+155930+156106)) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows Server 2003 x86-32 jvmwi3260sr6-20091001_43491 (JIT enabled, AOT enabled) J9VM - 20091001_043491 JIT - r9_20090902_1330ifx1 GC - 20090817_AA) JCL - 20091006_01 While the program is running, I tried to kill it and subsequently I found an orphan IBM JVM process in the process tree.

Any suggestions?

• SSRS2008R2 report times out, but the underlying query executes in the Management Studio

  - by Matthew Belk

  A customer of mine recently moved servers and the new server has SQL2008R2. His old server was SQL2005. The new server has substantially better CPU, RAM, and disk performance than the old, but several reports time out while executing. When I run the underlying query in the SQL Management Studio, the query executes in sub-second time. The exact error message returned via the Report Manager UI is: An error occurred within the report server database. This may be due to a connection failure, timeout or low disk condition within the database. (rsReportServerDatabaseError) Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It must be noted that this database is not just analytical; it's also fairly transactional, although the transaction volume is not exceptionally high. What can I do to improve the performance of the SSRS query engine? Are there settings in the data source I can adjust, or in the SSRS config files?

• How to deal with the extremely big *.ost files in a Terminal Server environment which is running out of space

  - by Wolfgang Kuehne

  Our Terminal Server is running out of hard disk space, and the major files which occupy most of the space are *.ost files of the Outook, which come form the users which use the Terminal Server all the time through remote desktop. The Outlook is installed on the Terminal Server and various users can use it. What would be a solution in this case. Is there a way to limit the size of the *.ost files? I read in forums that having the Outlook 2010 set up in Cached Exchange Mode isn't the best practice for an environment where the hdd space is a major constraint. First thing that came to my mind is using folder redirection, and place the ost files (together with the AppData forlder) in a network share, but this does not help, because the ost files are saved a part of the AppData folder which can not be redirected. Then I thought if it is possible to limit the size of the ost file? Or limit the time that it keeps emailed cached, say just emails from the last 6 months are sufficient. Another solutions that came to my mind, moving the ost files somewhere else, this required the old ost file to be removed, and creation of a new one. I am not quite sure if the new OST file will still have cached the emails which where available in the old ost, or will it start caching from where the other one left. What do you suggest?

• How can I recover XFS partitions from a formatted HD?

  - by giuprivite

  I deleted the partition table of my HD. I wanted to format another one, but by mistake, I formatted the wrong one. Then I also created some new partition on it. Now I would like, if possible, to recover my old data. The old configuration was this: A primary NTFS partition with Windows, and a secondary partition with four logical partitions: a swap and three XFS partitions (two for Ubuntu and OpenSuSE, and one with the home for both systems). This is the output I get when I run gpart in a terminal: ubuntu@ubuntu:~$ sudo gpart /dev/sdb Begin scan...

• Black Screen on Logon (windows 7 home premium)

  - by Blacknight334

  i have been having some trouble with a dell Xps 15 laptop that i recently purchased. it is under a month old, and a problem has occurred, upon logging on just after start up, the computer will just sit on a black log on screen (with the mouse still visible and active) for a few minutes. it is extremely annoying, especially when im in a rush. the laptop is under a month old. So far, i have tried to update the drivers, all windows update, and still, nothing. also, it doesnt seem to do it when i log into safe mode, or if it does, it will do it for less than 10 seconds, then load the desktop (in normal boot, it usually takes a few minutes). i have also run a number of the inbuilt diagnostics, but found no errors. i want to avoid having to do a system restore for as long as i can. does anyone know anything that can help? (the laptop is running a 500gb SSD, 2gb Nvidia 640m, 8gb ram, 3rd gen i7 quad core with 8 threads) thanks.

• JSP Content Issue in Tomcat

  - by gautam vegeta

  There is one application where I work where there are still manual builds used i.e manually moving the servlet classes and jsp files from Dev to QA and finally to Prod. This is the method used in this application which cant be changed for some wierd reasons.BTW this is not the problem. We did a manual build where we transferred jsp files from QA to PROD recently. And we noticed that the jsp file content does not correspond to the updated jsp's but have the same content to the jsp file which was present in the server prior to the deployment. We did not re-start tomcat since jsp files upon updation automatically changes its contents. This problem persisted even after 6 hours of deployment If we consider the time standards which are different which may cause some delay. So to fix this we had to individually go into every jsp file and just type something save it and delete this change and save it.Then it worked perfectly. But finally the jsp file content before and after was never changed we just did this to change the modification date. If we think in terms of timestamp problem how can this be possible coz the old jsp files which were present in the server prior to deployment was atlest one month old and the ones getting deployed were defenitely newer than that. Why did this happen? This did not happen when we did same type of deployments earlier. How can we prevent this from happening in the future.

• Computer resetting semi-randomly

  - by Peter

  Hi, I'm having a problem with my desktop whereby it sometimes resets itself semi-randomly. For example, I'll switch it on, it'll boot an OS and shortly after getting to the desktop it will immediately reset with no warning. The time isn't consistent - sometimes it does it before reaching login. I'm pretty sure it's not an OS thing; have tried Ubuntu and a Windows install and both exhibit it. It also doesn't appear to be heat-related because sometimes it appears to be able to "get past" it and will then run stably even under load; if anything it seems to be worse from a cold start. My gut feeling is some kind of power issue but I'm clutching at straws a little. Any suggestions on how I could go about testing it or trying to narrow the problem down would be appreciated. The machine is four years old now so while I can replace components if needed, it's not worth enough that I'm comfortable buying new parts without being pretty confident that they'll fix the problem. Thanks in advance for any help :) Edit: Okay, the motherboard is a MSI K8N SLI; CPU is an Athlon64 X2 4200+. Has one video card, a GeForce 7800GT. 1GB RAM, not sure of brand; 3 hard drives, two SATA and one PATA. Flashed motherboard to latest BIOS some time ago. Edit the Second: I thought I'd narrowed it down to the PSU for a while, but then it recurred again. I ended up pulling everything out but CPU, RAM and motherboard and it still seems to be stuffed (if anything, it's gotten worse in the last couple of days). I assume it's one of those three components, but the machine is old enough that I don't really want to spend money replacing any of them. So thanks for everyone's suggestions; much appreciated!

• Tri-head linux system with Xmonad: is it possible to have HW acceleration

  - by progo

  What means there exists to have three monitors, all controlled by Xmonad and have hardware 3D acceleration as well? I had the pleasure of using three monitors earlier this year, and while Xmonad and Xinerama handle three monitors easily, I had to throw in an extra display driver, and also let go of Nvidia's own TwinView (which is a hack on Xinerama). This left me with no HW acceleration and some flickering as double buffering wouldn't work with certain applications. However, the three monitors handle so beautifully that I had hard time coming back to two. I understand the easiest way to achieve HW-accelerated tri-head combo is to split into two Xorgs. I wouldn't be able to switch windows between the Xorgs, so I'm not really into this solution. What's more, having a cheap and old PCI card along with even slightly better PCIe seemed to slow things down. Even if I occasionally disabled the third monitor from Xorg configure, I couldn't get HW acceleration to work. Only after I physically disconnected the old PCI card, I could get the games back in business. Would a Matrox Dual/Tri-head2go and a powerful Nvidia GPU do the trick? I understand Xmonad can be configured to "believe" that a "single" (as Dualhead2Go will merge) 3360x1050 display is actually two different ones? So that Xmonad's Mod-w and Mod-e would work properly there.

• What is the difference between the Linux and Linux LVM partition type?

  - by ujjain

  Fdisk shows multiple partition types. What is the difference between choosing 83) Linux and 8e) Linux LVM?

• Real benefits of tcp TIME-WAIT and implications in production environment

  - by user64204

  SOME THEORY I've been doing some reading on tcp TIME-WAIT (here and there) and what I read is that it's a value set to 2 x MSL (maximum segment life) which keeps a connection in the "connection table" for a while to guarantee that, "before your allowed to create a connection with the same tuple, all the packets belonging to previous incarnations of that tuple will be dead". Since segments received (apart from SYN under specific circumstances) while a connection is either in TIME-WAIT or no longer existing would be discarded, why not close the connection right away? Q1: Is it because there is less processing involved in dealing with segments from old connections and less processing to create a new connection on the same tuple when in TIME-WAIT (i.e. are there performance benefits)? If the above explanation doesn't stand, the only reason I see the TIME-WAIT being useful would be if a client sends a SYN for a connection before it sends remaining segments for an old connection on the same tuple in which case the receiver would re-open the connection but then get bad segments and and would have to terminate it. Q2: Is this analysis correct? Q3: Are there other benefits to using TIME-WAIT? SOME PRACTICE I've been looking at the munin graphs on a production server that I administrate. Here is one: As you can see there are more connections in TIME-WAIT than ESTABLISHED, around twice as many most of the time, on some occasions four times as many. Q4: Does this have an impact on performance? Q5: If so, is it wise/recommended to reduce the TIME-WAIT value (and what to)? Q6: Is this ratio of TIME-WAIT / ESTABLISHED connections normal? Could this be related to malicious connection attempts?

• router only assigns small number of IPs

  - by Liam Coates

  Been having a problem with my router for a while now, might just be because it is really old but here's the problem: If a lot of computers are connected to my home network someone will get disconnected. They are assigned IPs and it seems like at a certain point (and I don't know how many) you either get assigned the same IP as someone else or something else is happening and you get disconnected - until i soft reset it and it works again which takes 30 secs. I'd say my tablet, my PC, my sisters iPad, 2 laptops and a netbook is the most that can be connected at one time so that is 6 but that should be fine. The only way I know this is the problem is because I turned on my tablet and I was online on my PC, got disconnected but my tablet was still connected, this is just after i turned the tablet on so I know my router is having difficulty with IPs, it is like it assigned the same IP to the tablet which then clashed with my desktop and knocked me off. I see that sometimes the following solves it as well so I wrote a batch file with a menu to execute these commands as I have to do it so often. ipconfig /release ipconfig /flushdns ipconfig /renew Any ideas? Or shall I just get a new router as this one is old and maybe can't handle giving out that many IPs? Cheers!

• How should I configure my Active Directory servers so that if one goes down, users are not kicked off SQL?

  - by Matty Brown

  Today, we shut down one of our Active Directory servers during office hours to check the loading on a UPS. Since all the server did was provide Active Directory in a separate building incase the main building caught fire, or whatever, we didn't think it would have any effect on our users. Seconds after the server was shut down, we had a dozen phone calls from users experiencing this issue:- [Microsoft SQL Server Login] SQLState: '28000' [Microsoft][ODBC SQL Server Driver][SQL Server]Login failed. The login is from an untrusted domain and cannot be used with authentication. Once we realized what had happened, we quickly rebooted the down Active Directory server. Problem solved. But why did this happen. And what if one day a server has a breakdown and is offline for hours, or days? Shouldn't the other Active Directory servers in the domain service authentication requests without disruption to users? We have 3 Windows Server 2003 Standard servers running Active Directory as Domain Controllers with Global Catalogs, all physically located on the same network at Gigabit speeds. I believe the domain was originally Windows Server 2000, or maybe even NT 4.0. Could the issue be to down to old Group Policies inherited from these old server OS's, or some default setting in Active Directory that needs changing?

• Turn off monitor (energy saving) while in text console mode (in Linux)

  - by Denilson Sá

  How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup. The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen) But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor? (maybe I should (cross-)post this question to http://unix.stackexchange.com/ )

• MicroSD card isn't detected by computer, apparently usable only with phone

  - by paulcjoubert

  I have a 4GB MicroSD card that apparently only works (in the sense that the device detects and can read and write from and to the card) with my old Nokia XpressMusic 5800 phone. I have taken pictures and recorded voice notes that were saved on the card. These are accessible after the card has been removed, which tells me that the problem isn't with the card. The card could also not be locked to the phone as it would at least be detected by a computer and it would be able to write raw data to it with dd, such as /dev/zero. Also, the card is not the Nokia card that came with the phone and I have done nothing that would have caused it to be locked. (I could not find anything on Nokia's website that helps, but then again... my search was not THAT thorough.) The card works on no other device that I have tried so far. I have tried it in my Canon camera (through an adapter), but it refuses to even boot with the card inserted. My card reader (via USB cable and hub) is detected as /dev/sdx with or without the card inserted. When trying to access the card I get an "No medium found". dmesg does not report any change at all when inserting and removing the card. I would obviously like to use my card on other devices - the phone is quite old - and even a likely explanation would help. Thankyou in advance! EDIT 1: I can use the card by connecting the phone to my computer, but this is impractical and would not allow me to use the card in any other device. EDIT 2: The data on the card is not important to me at all.

• what is the fastest way to copy all data to a new larger hard drive?

  - by SUPER user

  I was certain this would have been covered before, but I cannot find an answer amongst all the almost-duplicates that come up; sorry if I've missed something obvious. I have a full 320gb disk inside my machine, a new 1tb disk to replace it, and a USB 2.0 chassis. It is only data on a single partition, no OS/apps involved, and the old drive will be kept somewhere as backup (no secure wiping etc). The simple option would be to put new disk in USB chassis, copy files, then swap them over. But for USB pen drives, reading is around 4x faster than writing. If the same is true for a USB SATA chassis (is it?) then it would be significantly faster to swap the drives first and read from the old drive over USB, right? Then the other consideration is that copying lots of files is usually slower than a single file of equivalent size. Is Windows 7 smart enough to do everything in a single lump like that, or is there specialised software that should be used instead? (Even if SATA-SATA copying is faster than involving USB, knowing what to do when it isn't an option is useful information.) Summary: Does a USB SATA chassis suffer from a read/write inequality? (like a USB pen drive does, but unlike a direct SATA connection) Can Windows 7 do sequential access? (I can't find confirmation if Robocopy does this.) Or is it necessary to use a bootable CD/USB with something like Clonezilla to achieve sequential copy speeds?

• Update BIOS on Sun Fire X4150 server

  - by Massimo

  I have some Sun Fire X4150 servers with a very old BIOS release (1ADQW015), which seems to have some compatibility problems with WMware ESX Server 3.5 and Windows 2008 R2 virtual machines; so I want to update the BIOS on them. The problem: according to this page, if your servers run ELOM (mine do), you first need to update to the latest ELOM release, then to the interim transition release, then finally you can update to the latest one. Ok, I'm willing to do that... but it looks like Sun (now Oracle) will happily let you download the latest firmware DVD (3.3.0), but it will not let you download the transition release (2.0) if you don't have a support contract. Well, I actuall don't care at all about the servers' management controllers (we don't even use them), so upgrading from ELOM to ILOM is totally irrelevant to me; but I need to update the servers' BIOS. So my question is: can I update the servers' BIOS to the latest version without doing the full ELOM-to-ILOM migration, or will this not work (or even make the servers unusable)? Do BIOS versions and SP ones need to be matched, or can one be updated without bothering with the other? Bonus question: if this whole ELOM-to-ILOM thing actually is needed in order to update the BIOS, can that 2.0 CD-ROM be obtained without having a support contract with Sun/Oracle (which we are definitely not going to sign, being that quite old hardware)? Update: I tried upgrading only the BIOS on one of the servers, and it didn't boot anymore. So it really looks like a full firmware upgrade is needed, and the management controller and BIOS versions should be kept in sync. So... where can I find that *&!£%$% 2.0 CD-ROM? Or at least the transition firmware that can be found on it?

• Have it fixed or buy a new one?

  - by Workshop Alex

  My dual-monitor system has just become a single-monitor system again when the older monitor decided it would be nice to just turn to black. It's a Samsung LCD monitor and is over three years old. Not sure if the warranty is still valid but I just wonder what option would me more efficient: 1) Have the monitor fixed for a small amount. 2) Buy a new monitor for a slightly bigger amount. When monitors were still expensive, I wouldn't doubt about this and would just have my monitor repaired. But prices are so low nowadays, (and repairs are expensive) that I wonder if it's worth the trouble... Of course, I'm in no hurry since I still have another monitor. It's just that I liked the dual-monitor setup. Solved! Just ordered a new monitor. A Samsumg Syncmaster T260HD 25,5". Much more than it would cost me if I just had my old one repaired but I noticed that this one has a build-in TV tuner, plus speakers. It's way more expensive than a repair, but it's worth the additional value it provides.

• What can I do to prevent system power downs?

  - by Joe King

  Yesterday I was given my brother's old laptop - core i7, 2.67GHz, 8GB RAM, 128GB SSD, Win7 64 bit. It's a Sony Vaio Z11. Approx 18 months old. When running something computationally intensive, the fan starts up and after about 30 secs it just powers itself down with no warning. I guess it is overheating. There is nothing in the event logs to suggest what is causing it - the only thing I see is "the last system shutdown was unexpected" or something similar. This is a problem for me because I use a lot of number crunching apps, which pretty much makes it useless to me. I would like to know if there is anything I can do, other than the obvious things I've done already - open up and clean out dust, re-install the OS. According to my brother, this problem started about 6 months ago when it was already outside warranty. If it's just used for simple things - web browsing, word processing etc, the problem does not occur. Any ideas for what I can do to fix this ? Update: I found that the laptop has 2 hardware settings for graphics: Speed and Stamina - the Speed setting seems to use an nvidia GEforce GT 330M, while the Stamina setting uses an Intel chipset. With the setting on Speed, I can hear the fan the whole time, and the system powers down after a short while (5-10 mins) even just doing basic tasks (browsing this site for example), but doesn't shut down if I just leave it switched on. In this mode it also sometimes just freezes the screen and I have to power off myself. However on Stamina setting it only powers down when doing number crunching and never freezes the screen.

• PC shut downs automatically after 10-20 second. No POST screen, no beeps

  - by emzero

  I have this not-so-old computer that's not being used for a year or so. Specs: Motherboard: ASUS PN5-E SLI CPU: Intel Core2Duo E4300 RAM:2x2GB SuperTalent DDR2-800 VGA: Zogis GeForce 7950GT PSU: Vitsuba San-55-S 550w HD: No hardrives yet When I power on the computer, everything seem to start, but right away the whole system shuts down. I've removed and changed the RAM sticks, take out the VGA, everything I could think of. So what could it be causing this? The PSU? The motherboard is dead? The CPU? Any help to isolate the problem will be useful. Thanks PS: Please don't close the question, this could be helpful to anybody having a similar problem, even with different hardware. UPDATE I've removed the old thermal paste and apply a brand new one. I also cleaned every dust using a high pressure gas dust remover. Checked for bad capacitors, all of them seem ok. Opened the PSU, removed big giant dust balls, cleaned with high pressure dust remover. Still the same problem, but now it stays powered on for almost 20 seconds maybe. But no POST screen, no beeps at all, nothing. So I suspect it's a motherboard or PSU failure. Unfortunately I don't have an energy tester to test the PSU... Don't know what else to try. I don't have another 775-motherboard to test the CPU, RAM and VGA with it.

• Window 7 Computer name changing on its own?

  - by DC

  Very odd problem... I have a Dell Latitude D830 with XP Pro that has been running on my local domain for many years. I recently Installed Windows 7 Enterprise on the D830 using a brand new HDD so that I could still use XP if I needed by just swapping out the HDD's. I added the W7 installed system to my domain using a completely different machine name than that used for the XP system and everything seemed to be functioning as it should. On boot up over the last 2 weeks or so I occasionally (3 times now) get to the login screen and try to login to the domain only to get an error saying that the Computer name is not a trusted machine in the domain I'm trying to log in to. Come to find out that the machine name on the W7 system has been changed somehow to that of my old XP system. If on the W7 system I then change the name back to the correct name, disjoin the domain, reboot, add the machine back into the domain … all is well for an unknown period of time until this happens again. This last time, I know for a fact that everything was fine the day before when I shut down the system. I came in today, powered up the system and the machine name had been changed to that of my old XP system again. Has anybody else seen this behavior or hav any ideas on what could be causing it? Thanks!

• How can I make Internet Explorer 6 render Web pages like Internet Explorer 11?

  - by gparyani

  Now, I know that this may seem like a bad question in that I can just upgrade to Internet Explorer 8, but I am sticking with IE6 in that IE8 removes valuable features, like the ability to save favorites offline and the fact that a file path turns into a Windows Explorer window and typing a Web address into Windows Explorer changes it into an IE window. I know that Internet Explorer 6 does a really bad job at rendering some pages. I know of the Google Chrome Frame extension that brings Chrome-style rendering into IE, but that will soon be discontinued. So, I tried another thing: I know that C:\Windows\System32\mshtml.dll contains the Trident rendering engine that is used by IE, so I tried something: I first backed up the original file by renaming it on Windows XP to mshtml-old.dll, then I tried to copy in the DLL from a computer running Windows 7 with Internet Explorer 10. I noticed that, after copying, the system had replaced the new DLL with the old one, but left the one I backed up intact. Is there any way I can get the system to not replace the DLL like that so that I can transfer in IE11's mshtml.dll into Windows XP and make IE6 render like IE11? I'm looking for an answer that describes how to tweak my system to make IE6 render like IE11 (or IE10), not one that tells me to upgrade IE or install another browser. I don't care how tedious the method is, just as long as it works.

• Solid State Drive Occasionally Freezes For A Minute While OS Is "Beach Balling"

  - by Boris_yo

  Almost a month ago I bought Intel 330 128GB solid state drive, migrated my data with Intel branded limited-feature Acronis from old HDD to new SSD, optimized with Intel Toolbox and started using it. Occassionally I get close to 1 minute freezes while seeing operating system "beach balls" and animations still work, I can interact and click on something but nothing responds, nothing loads. Recently a couple of such freezes occurred in shorter amount of time in a row. I have noticed that if I stop interacting with laptop, the freeze lasts less time than if I was interacting with laptop. But the bigger problem is when freeze just does not end and computer keeps being stuck unlil it is more than half hour and I run out of patience to keep waiting and feeling I need to restart the system because I am not getting anywhere. Such freeze happened while laptop was cold booting into Windows 7. This is when freeze hang occurred and I had to restart, only later to be greeted with Windows recovery screen stating something about faiure of boot sector and asking to insert Windows repair CD. But after I restarted, Windows booted successfully and all was well. I have filmed video of freeze hang occurring in cold boot which you can see here (on video page look below for description): http://www.youtube.com/watch?v=8b7MQlcDTUs As I have mentioned in the beginning, the SSD is less than a month old but here is S.M.A.R.T statistics just in case (TRIM is enabled btw according to CrystalDiskInfo): I want to emphasize that this SSD is the only drive I have, yet it is working in RAID mode (it was enabled initially in BIOS by previous laptop's owner) on Intel Rapid Storage drivers. I am contemplating about switching to AHCI mode but want to be sure this won't cause data loss. Additionally, the stock firmware is the only firmware available currently, yet Intel does not respond to my posts in their community board. If anyone here has this SSD model or generally has experience with SSD drives, I would love to know your thoughts.
