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. > $ ps -elf | grep csrss|more SYSTEM 648 572 0 04:45:04 CONIN$ 0:16 C:\WINDOWS\system32\csrss.exe Obje ctDirectory=\Windows SharedSection=1024,3072,512 Windows=On SubSystemType=Window s ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=w insrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16 amit 2952 1012 0 Jun 07 CONIN$ 0:00 grep csrss < Apologize for the UNIX like PS...

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! "There is no such thing as a stupid question. There are only stupid people."
