how to resolve the access denied error message while opening application with .msc extension?

OS with SBS Server 2003 running Ninja Email Security, Symantec antivirus 10.2
While opening any application with .msc extension (such as dsa.msc, gpedit.msc etc), I get an access denied error message.
I have tried the following with no success.
>cd /d %windir%\system32
>regsvr32 /n /I userenv.dll
>cd wbem
>mofcomp scersop.mof
>gpupdate /force

Any help with be appreciated.

Are you running the application with administrator credentials? May be that the probram will not load for standard users? Try using the Runas command

Re-associated the file type .msc with the correct mmc.exe application and the management consoles should all open fine. The message access denied is a little misleading, as access is not denied when using other methods such as adding a snapin in a new mmc console.

It sounds like the extension .msc isn't associated with mmc.exe

Try re-associateing them by doing the following:

Navigate to a .msc file such as dsa.msc which should be located at "c:\windows\system32\dsa.msc"
Right click and select properties of the .msc file and if you notice that its set to open with "Unknown application" change it  to open with Microsoft Management Console, by clicking  "Change..." (next to "Opens with"), then "Browse..." and navigate to "c:\windows\system32\mmc.exe". Click "Open", hit "OK", and then close the Properties dialog. After that, the .msc applications should work properly.
