• Windows 7 disk backup and clone for deployment to multiple systems

  - by gregmac

  I'm in the process of deploying some new PCs (there's only 8), all identical hardware. What I'd like to do is install Windows 7 (64bit), join to domain etc, install a bunch of other software, and then clone that drive to multiple other machines. I'd also like to be able to use it as a backup image, so the machine can be restored back to that image at some future date. I understand this involves at least sysprep, but I am confused after reading some tutorials that talk about using Windows Automated Installation Kit, or hacks with the registry and custom-build batch files. This process seems overly complex to me: I did something similar 10+ years ago, and and don't remember it being this bad. Surely things have improved in a decade? There's also some products that involve having network servers running deployment software, network boot, etc etc.. this is way more than I want to set up. My systems are all identical hardware. Is there a simplified way to clone PCs? Preferably (since I'm a lazy developer, and not an IT admin) I'd like to find some off-the-shelf product that I can run after I get the machine setup, that will spit out a bootable DVD I can run on all the other systems, which will boot up, ask for a computer name, join it to the domain, and that's it. Does such as product exist?

• Setup link aggregation and jumbo frames on VMware ESXi 4

  - by Sysadminicus

  I'm setting up an ESXi 4 server to connect to an NFS datastore. I'd like to bond two of the NICs together and use jumbo frames for the NFS connection on a private (non-management) network. I setup a new switch with the 2 NICs and am able to connect to the NFS share over it, but could use some guidance on getting jumbo frames and link aggregation/bonding/teaming working.

• run as dialog always pops up

  - by user12006

  I recently got some malware on a machine that I don't use for much (partly intentional). I've cleaned it, but now everytime I open any .exe the 'Run As' dialog pops up asking me which user I want to use to run the program. What causes this, and what's the fix for it? edit My process to remove the malware was as such: Disconnected from the network Deleted DisableTaskMgr reg key Inspected with Process Explorer and Task Manager and noticed that all applications were being run within another executable located in Documents and Settings...\Temp\Some.exe The system tray application was also in Documents and Settings...\Temp\SomeOther.exe I suspected that a service was in place as the system tray application would restart if it was killed, but couldn't find any service that I didn't recognize. Removed permissions from Some.exe and SomeOther.exe (on those files only) Restarted and deleted Some.exe and SomeOther.exe Deleted startup entries that were created Ran AVG Free and Windows Defender to remove anything else (they would be killed immediately before the two .exe's were removed) Cleaned registry via CCleaner note that system restores would finish saying something to the effect of 'couldn't restore system: there were no changes made'. I attempted to restore to a week ago, and I only got the malware yesterday.

• How can I find the space used by a SQL Transaction Log?

  - by Sean Earp

  The SQL Server sp_spaceused stored procedure is useful for finding out a database size, unallocated space, etc. However (as far as I can tell), it does not report that information for the transaction log (and looking at database properties within SQL Server Management Studio also does not provide that information for transaction logs). While I can easily find the physical space used by a transaction log by looking at the .ldf file, how can I find out how much of the log file is used and how much is unused?

• Should I move to an Azure database?

  - by Mike Flynn

  I am currently using a database from an installed instance on my web server in a VM on Azure. I was thinking about moving it to an actual Azure Database so I could load balance the web server. Does the Azure database work the same way as a straight install? Will it cost more or the same since I am just moving to a new server? Basically looking for advantages and disadvantages. I am familiar with SQL Server Management Studio.

• Makecert.exe hangs

  - by Robert

  I was following the steps in Scott Hanselman's blog post describing how to create a certificate authority and code signing certificate for PowerShell scripts. Initially, I created the certificate authority and a personal certifcate and used it to sign a powershell script successfully. All went as described in the blog post. The problem starts (as most do) when I did something that was (probably) stupid, although it seemed reasonable at the time. I wanted to start over and repeat the process again with a clean slate, so from the mmc certificates snap-in console, I deleted the personal certificate and the certificate authority I created previously. After that any time I try to use makecert, (just as I did the first time around), makecert either hangs or faults (which prompts to end or debug). Did I hose something up by deleting via the certificates snap-in? It didn't complain or warn me that it could be potentially hazardous. Is this just coincidence and something else entirely could be hosed? I have Event Log entries from the times when makecert crashed, which all look very similar; here is one: Log Name: Application Source: Application Error Date: 8/5/2009 3:55:04 PM Event ID: 1000 Task Category: (100) Level: Error Description: Faulting application makecert.exe, version 6.0.6000.16384, time stamp 0x4545910b, faulting module ntdll.dll, version 6.0.6002.18005, time stamp 0x49e03821, exception code 0xc0000005, fault offset 0x00067409, process id 0xe58, application start time 0x01ca160efdf30625. Anyone have any ideas as to what exactly caused this and/or what I can do to fix it. I'm on 32-bit Vista Enterprise w/SP2.

• Is it possible to be a professional studying on your own?

  - by Marc Jr

  I read economics at university(nothing to see with linux, isn't it? :P). I have some basic knowledge about booting process, Linux Kernel compiling from source and stuff like that. But of course I have still much to learn sometimes some errors appears and "voila" I am lost. I had: Ubuntu, Fedora, OpenSuse, Arch.. using Gentoo now. I'd like to know what you linux users, professionals, administrators... would think it is the best way to learn linux in a professional way. Is it worth studying it and passing the LPIC test enough to work in the linux world? or do I need going to IT uni? I've heard LFS is a good way of learning about linux, is that real? I've been thinking about getting to LFS learn about more deeply about the linux process and learning scripts. It is possible to do this way? if anyone has a tip or a good way of doing, maybe someone did it. Any tip is very welcome. Words from a person in love with linux. :D The best, Marc

• Enable FTP Publishing on IIS7?

  - by David Lively

  I've followed the steps in http://learn.iis.net/page.aspx/303/adding-ftp-to-a-web-site/ However, when I get to the part where it says to click "add ftp publishing to website", the option is not visible in the IIS management console. I've verified that the "FTP Publishing Service" is installed in the server manager, and I can see it running in the services applet and via netstat -a. Suggestions?

• Windows Vista: Screen remains darkened for 30-60 seconds *after* UAC prompt

  - by sf2k

  Fixing someone's Vista computer. Process: I click any program or process that opens a User Account Control prompt. Screen goes dim so you may hit Continue to perform a secure user action. I click Continue Screen goes black for 30 seconds to 1 minute while you wait for the screen to return. In another example I click Cancel and screen still then goes black for 30 seconds to a minute. In that timeframe a chime goes off while you wait. (No chime if it was being cancelled.) Then screen comes back to continue with whatever. Something is occurring after the UAC prompt. Considering everything is practically a UAC acceptance this can get pretty annoying pretty quickly. Laptop has external monitor to regular external plug. Works fine. Laptop also has USB IOGEAR additional external video card. This is problematic but when unplugged same above behaviour occurs. I've ruled out monitor interference since same blackout after the UAC prompt appears with external monitors plugged in or when rebooted with no external monitors. Any suggestions on how to address this problem?

• "postgres blocked for more than 120 seconds" - is my db still consistent?

  - by nn4l

  I am using an iscsi volume on an Open-E storage system for several virtual machines running on a XenServer host. Occasionally, when there is a very high disk I/O load on the virtual machines (and therefore also on the storage system), I got this error message on the vm consoles: [2594520.161701] INFO: task kjournald:117 blocked for more than 120 seconds. [2594520.161787] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162194] INFO: task flush-202:0:229 blocked for more than 120 seconds. [2594520.162274] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162801] INFO: task postgres:1567 blocked for more than 120 seconds. [2594520.162882] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. I understand this error message is caused by the kernel to inform that these processes haven't been run for 120 seconds, most likely because a disk access to the storage system has not yet been processed. But what is the effect on the processes. For example, will the postgres process eventually write its data when the storage system is idle again after a few minutes, so that all data is still consistent? Or will it abort the write, leaving some tables in an inconsistent state? I certainly expect that the former should be the case - if the disk access is slow, postgres (or any other affected process) should just wait as long as it takes. I can live with the application hanging for a few minutes. But if there is a chance for data corruption then any of these errors is really bad news. Please advise what to do here.

• Domino nchronos.exe multiple instances causing server to die, and Sametime problems

  - by Kevin

  I've had this problem for a few months now. I thought it started when I installed the Traveller software on the server to add ActiveSync support, but I removed that and the problem still persists. Basically new instances of "nchronos.exe" keeps spawning (and not ending), so over a period of a few days the server eventually gets drowned in nchronos.exe processes, stops responding and I need to kill Domino. My process count the last time was up at about 330, and when I killed it and restarted the Domino my process count went to 160. I'm running Domino 8.5.1 with Fix Pack 2. I don't know if it's relevant, but my Domino server was also acting as a Sametime server. At around the same time that nchronos started playing up sametime also stopped working. None of my users can connect to sametime and in the domino log it keeps telling me "stpolicy.exe" has terminated. I've googled for that and tried a few things, but nothing seems to make sametime work again. Any thoughts?? Cheers, Kevin

• Batch update users on Active Directory

  - by FrancisV

  We have around 1000 users in the Active Directory (on Windows 2008 R2) and we would like to batch update a field (student/employee ID number) from the school management system into their existing Active Directory accounts. Obviously, each student/employee ID is unique and needs to be matched to their current Active Directory account. How can this be done? Is there a tool available for this purpose?

• Why does ATI 5570 HD video card driver installation cause Windows 7 To Blue Screen?

  - by Mort

  This one is for the hive mind. I have a brand new Dell Optiplex 760 workstation with 4 gigabytes of RAM running Windows 7 Professional (32bit). This is a new box with nothing installed other than what was provided for directly by Dell. I installed a Saphire ATI PCI Express 5570 HD. Upon trying to install the 10.4 Catalyst drivers the system will blue screen. It blue screens during the hardware detection phase of the installation process. I have already performed the following trouble shooting steps: Changed system RAM Installed only 2 gigabytes of RAM Installed different versions of Catalyst drivers (10.4 - 9.12) Tried to install video only component of driver (vs entire Catalyst suite) Made sure Windows 7 was fully updated Flashed mother board BIOS to current version Removed and re-seated video card Contacted ATI Support (We all know how this went......) Verified supply outputting properly The blue screen error (via Windows BugCheck entry in event log) is a 0x000000CA and refers to a plug and play error most likely caused by a bad driver. The problem is that the driver installation process never gets far enough to actually install a driver. The resolution center in Windows provides a solution of installing the 10.4 Catalyst driver to resolve issue (which fails). Looking for some alternate views to resolve.

• Microsoft Security Essentials & MsMpEng.exe hogging resources

  - by Mike

  I've been using MSE for a couple months now, never had a single problem. All of a sudden the process "MsMpEng.exe" will randomly go crazy and hog all my system resources so I can't do anything unless I kill it in the task manager. (I've quit the program for now and my comp is running smooth). When I restart the program, reboot, whatever, it goes off and hogs all the resources again after a couple minutes. If I kill the process it will go away and then come back a couple minutes later and do the same thing. I've scanned with MSE, another antivirus and malware with no probs. Any ideas? Should I uninstall and find something else? The thing is I've liked it so far. I'm running Win7 64-bit. Also, I'm not running any other conflicting security programs. This is the only one on my PC right now. Windows Defender is also off.

• Temperature monitoring on Dell Precision M4500 under Linux: sensors-detect doesn't, what next?

  - by Tikitu

  I have a Dell Precision M4500, Intel Core i5 CPU, running Linux (Ubuntu Lucid), and would like to keep an eye on CPU temperature. I've tried lm-sensors: sensors-detect didn't find any sensors; following its hint ("This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.") I tried acpi -V but got nothing thermal. The Gnome panel applet "Hardware Sensors Monitor" reports on GPU temperature but nothing else. What should I be trying next?

• Unable to activate Windows XP

  - by Josh Kelley

  The latest round of Patch Tuesday updates left my Windows XP computer unbootable. ("Fatal System Error: The Windows Logon Process system process terminated unexpectedly.") After much messing around with the recovery console, an XP CD's repair mode, and manually copying registry files around, I have a system that can boot again. However, I overwrote my OEM XP installation's activation information while trying to run a retail XP CD's setup, so it needs reactivation. Here's my problem: I cannot activate it at all. I log in, Windows tells me I have to activate to continue, I click Yes, and absolutely nothing happens: no windows, no response to keyboard or mouse, no response to Ctrl-Alt-Del, nothing. Safe mode works, but I can't activate in safe mode (EDIT: not even safe mode with networking). I read a trick online of pressing [Windows Key]+U to bring up the Microsoft Narrator, and that works, but clicking its Microsoft Web Site link does nothing. My last attempt to resolve this was to reinstall Windows off of the OEM CD. Now I have two parallel Windows installations, both on the same hard drive, one with all of my stuff and no way to activate it, one fully activated with no usable programs. Any ideas? Any way to activate in safe mode? Any way to copy activation information from my activated installation to my unactivated installation (since they're both on the same hard drive)?

• Paused BitLocker encryption because no longer want to encrypt the hard drive - how do I get out of encrypting?

  - by Matthew Nagear

  I'm hoping someone can help. I'm not a techy and can't seem to find the same question already answered. I went to encrypt (using BitLocker) a Buffalo hard drive but after it took about 1 min to reach 0.2% 'encrypted' I decided to pause and eject, thinking this would have ended the encryption process. However, I had already assigned a password to it on the instruction pre the encryption beginning. I've since connected my hard drive again and I'm asked to input the password. If I don't I cannot access the drive. However, if I do, I CAN access the files but straight away the little BitLocker Drive Encryption dialogue box comes up saying Encryption in progress.. which I have the option to Pause. So I hit Pause straight away as I do not want to go through with the encryption. Is there any way I can stop the process and decrypt before encryption is completed? Or am I forever going to need to Pause quickly and eject. I fear that will affect my hard drive longer term. Thanks.

• Apache2 - 500 internal server error

  - by Lucio Coire Galibone

  i'm running a VPS with Linux CentOs 6 with 4 GB of RAM, 10 GB of HD and 2 virtual CPU Intel(R) Xeon(R)CPU L5640 @ 2.27GHz. As my host says each virtual CPU must be at least 0.5 physical cpu. At certain times of the day, those with more traffic, trying accessing my php script i receive intermittently "500 internal server error". I activate logging to debug level from apache, and also the PHP logging with E_ALL, but I can't find reference to Error 500 in any logs(I checked the right logs!). I haven't got any .htaccess file in path script. The strange thing is that the error start at first php line in the script (the previous html displays correctly, but at the first php line the script send 500 error). The cpu load is always good (max 0.15 0.08 0.01) and RAM is close to 95% but it arrived to swap just 2 times in a month with 2-5 MB. Apache works with prefork with this values: <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 280 MaxClients 280 MaxRequestsPerChild 4000 </IfModule> Everthing works correctly and I don't get any error in quiet times, but i start receive errors when traffic rises (6-9000 visits per hour). Can i solve the problem increasing resources? (i can upgrade RAM up to 16 GB). It can depend from reaching MaxClients (but apache must write it on log, right?)? If I upgrade RAM to 6 or 8 GB i have to calculate MaxClients value with this? MaxClients = Total RAM dedicated to the web server / Max child process size Max child process size is around 20M. How else can the problem be? Thanks in advance

• Nginx's speed, and how to replicate it [migrated]

  - by Mediocre Gopher

  I'm interested in this from more than an academic standpoint rather than a practical standpoint; I don't plan on creating a production webserver to compete with nginx. What I'm wondering is how exactly nginx is so fast. The top google response for this is this thread, but it merely links to a cryptic slideshow and a general covering of different io strategies. All other results seem to simply describe how fast nginx is, rather then the reason. I tried building a simple erlang server to try to compete with nginx, but to no avail; nginx won out. All my server does is spawn a new process for each request, uses that process to read the file to a socket, then closes the file and kills the thread. It's not complicated, but given erlang's lightweight processes and underlying aio structure I thought it would compete, but nginx still wins out by a consistent 300 ms average under a heavy stress test. What is nginx doing that my simple server isn't? My first thought would be keeping files in main memory instead of tossing them between requests, but the filesystem cache does this already so I didn't think it would make that great of difference. Am I wrong? Or is there something else that I'm missing?

• The physical working paradigm of a signal passing on wire.

  - by smwikipedia

  Hi, This may be more a question of physics, so pardon me if there's any inconvenience. When I study computer networks, I often read something like this in order to represent a signal, we place some voltage on one end of the wire and the other end will detect the voltage and thus the signal. So I am wondering how a signal exactly passes through wire? Here's my current understanding based on my formal knowledge about electronics: First we need a close circuit to constrain/hold the electronic field. When we place a voltage at somewhere A of the circuit, electronic field will start to build up within the circuit medium, this process should be as fast as light speed. And as the electronic field is being built up, the electrons within the circuit medium are moved, and thus electronic current occurs, and once the electronic current is strong enough to be detected at somewhere else B on the complete circuit, then B knows about what has happend at A and thus communication between A and B is achieved. The above is only talking about the process of sending a single voltage through wire. If there's a bitstream and we need to send a series of voltages, I am not sure which of the following is true: The 2nd voltage should only be sent from A after the 1st voltage has been detected at B, the time interval is time needed to stimulate the electronic field in the medium and form a detectable electronic current at B. Several different voltages could be sent on wire one by one, different electronic current values will exists along the wire simutaneously and arrive at B successively. I hope I made myself clear and someone else has ever pondered this question. (I tag this question with network cause I don't know if there's a better option.) Thanks, Sam
