Unable to access the Computer Management

[Dhananjay]

I do not know if it's a bug or not but when I right-click on My Computer, and I choose Manage, nothing happens! In fact I see something that starts but closes immediately. Through the control panel, there is no problems!
Someone faced or had this bug already? Thank you

Please read the following Microsoft KB that applies to Windows 2K however the same process should apply to XP:

Other then that you can try and do a System File Check,

Start > Run > "SFC /SCANNOW"

If you are on Vista and if you turned off UAC then turn it back on. Open the Help and Support app and search on 'UAC OFF'. It's always possible some kind of Malware has changed the file association for *.msc. Since you know its name, you should have no problem running the command:

MMC compmgmt.msc
