"Disable failed No devices disabled" devcon.exe | How to disable devices from command prompt

 This article will help you in Disable or Enable devices from command prompt. And also this will discuss about the error u may likely to encounter.

It will be really good rite, when you can disconnect your modem or internet connection in one click after you are finished with it. This article will help you to do that.

First you need to have devcon.exe. An alternate to device manager which can be run through command prompt.

Download the devcon.exe from the below link

http://support.microsoft.com/kb/311272 

Once you downloaded the devcon exe file, extract  the exe and paste it inside c:\windows\system32 folder. That's it you are ready to run it. 

 I've read the above procedure in a blog, and wanted to try it.  But i was getting this message..

"
C:\Windows\system32>devcon disable *mouse*
HID\VID_04CA&PID_0030\7&3A7DF96F&0&0000                     : Disable failed
No devices disabled.
"

After some digging i found the the 64 bit version of devcon available to download form Microsoft website is not compatible for windows 7 64 bit. You will need to extract it from server 2003 64 bit dvd.

Once it's done it will work like a charm. I've extracted the 32 and 64 bit version devcon.exe from server 2003 dvd and uploaded it. You can download it from below links..

Devcon.exe 32 bit

Devcon.exe 64 bit



Hope this helps..

"the service did not respond to the start or control request in a timely fashion" Windows deployement services (WDS)

  This is the message i get when i'm configuring windows deployement services in a IBM x3650 M3 server with Xeon processor.
   Initially i thought that it would be a issue with network configuration, share permission and stuffs like that...


But even after checking all the possiblities the server gave me the same message. Then i went to event viewer for further digging. In Event viewer out of my luck no further information except the below.

  It was giving me event id 257 repeatedly with a message "An error occured while trying to start windows deployment service"  and that's it.. I ran out of ideas.

  A research (googling) taught me that the wds service is not capable of handling more that 20 logical processors assigned to host server. OMG.. Then i checked my server's specs, it has 6*4=24 logical processors. Damn!..

  From elevated command prompt i ran the below command, to set the maximum logical processor as 20 in that server as a test.

bcdedit /set {current} numproc 20

and restarted my computer.

  Voila, After a restart my wds started working as expected. But i cant use all my resources.

  Expecting an update from microsoft to address this issue.

if you want to revert back youu can run the below command in elevated command prompt.

bcdedit /deletevalue {current} numproc

Hope this helps...

How to rectify "unable to communicate with the reporting component" in sepm server

Hey friens, Recnetly was installing Altiris IT management sollutions through symantec installation manager to test it's ability in my organization's environment, But as a part of pre request check it asked me to configure script mappings for IIS. I did as it said and it passed the pre request check. Successfully installed altiris IT management sollutions. Thank god. I did it..


But when i open my symantec endpoint protection  management console, i was shocked as it display "Unable to communicate to reporting commponent" error when i login to my console and there were a white blank screen on HOME, MONITOR and REPORTS tab. Oh my god, i forgot i had sepm console in the same server, and now i made a mess in IIS...

Found many procedures to troubleshoot this issue, None of them worked for me.

Tried resetting IIS, Tried reconfiguring ODBC, tried restoring apppoolsettings in IIS blah, blah..... None of them set that right.

So i decided to go ahead with repairing sepm installation as i cannot let that error persists for one or two days and open a support case in symantec. Because i had configured almost 12 scheduled reports that run daily.

As i was ready to repair sepm installation i took database backup and keystore backup, as i might need it later to restore if anything goes wrong.

Started repair, after 5-10 mins it asked me to reconfigure sepm, I specified same configurations as i had set my server earlier. Volia my console came online again. The scheduled reports are also working now.. Thanks to repair. :)

Hope this post helps you..

How to recover "cannot create the window" error in Visual studio 2010 (Vs2010)

    I got this error recently, while configuring visual studio 2010 for one of my client. But he has visual studio 2008, and it's working flawlessly. While opening vs2010 alone the error "cannot create the window" appears, and vs2010 doesn't open.

    As it did not happen earlier and vs 2008 is working well, i though the problem must be either with the installation or with the third party add in installed. So I started reinstalling it.

    Even after re installation of vs2010, the same error pops and vs2010 doesn't open. Then i started digging the information about the add ins installed. After two hrs of hopeless browsing and r&d, I was tired and wanted to take some rest...

   After some time something strike my mind, and i started to feel that, the problem is lying with .net framework 4 and related updates. First i tried to uninstall .net framework 4 extended and it failed as we need to uninstall .net framework 4 client profile first. I could not uninstall the .net framework 4 extended even after removal of .net framework 4 client profile.

    I downloaded the .net framework cleanup tool and with the help of this tool i succeeded uninstalling .net framework 4 components.

   After a couple of restart the .net framework 4 components installed through windows update. Finally voila, VS 2010 started to work like a charm.

  The corrupted .net 4 components did not affect VS 2008 as it uses 3.5 components.
