I have problem opening MMC Console and any msc files in Control Panel/Admin Tools.
I ran into the same problem somehow while trying to install Cisco CheckPoint VPN.

I found several related problems but none of the workarounds resolve my issue.

This problem seems very similar to post at: http://www.computing.net/windowsxp/wwwboard/forum/76985.html
and http://www.ruffles.org.uk/dev/qna.html

I ran the above mentioned sfc but the problem did not get fixed.

I cannot open Any of the MSC files in Administrators tools section of control panel.

I also checked the registry entry for ApplicationData(see HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\AppData) and it was ok. However I could not run "regsvr32 C:\Windows\system32\msxml3.dll", I get an error "LoadLibrary("C:\Windows\System32\msxml3.dll") failed - A dynamic link LIbrary(DLL) initialization routine failed"

Any ideas what else can I try?

Might try from another computer. Make one on another computer and copy it over. Might have been denied access are you at admin? Try it in safe mode. I forgot the way mmc works but that transport code might be off. What is it nlvp or ldpm or something I forgot. Guess you could try a restore point if you know it did work at one time.

Jeff,
Thanks for your help however I tried copying the files but the file sizes were same and it did not complain. I'm not sure about nlvp or ldpm, what is that?

I was thinking of doing a complete overwrite but that's a long drawn out process. Any idea why "crss.exe" process continues to run even past "sfc /scannow" completes checking the system?

It's been running for over 12hrs on this system but the problem's still not fixed.

Apologize for the UNIX like PS... As you can tell, I'm not much of a Windows geek!

Hi amit,

I have exactly the same problem have you a resolution yet? If/when you do can you email me ?

Thanks,

Steve.

run Regsvr32 "C:\WINDOWS\system32\msxml3.dll"

I can't tell you why it works, but it fixed the problem for me!
