I was working on a client’s Microsoft Server 2003 box, when I added some MS patches and then recieved the following error:

“MMC cannot open the file C:\WINDOWS\system32\rrasmgmt.msc.

This may be because the file does not exist, is not an MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to the file. ”

Ah nooooooooooooooo… I screwed the server. Well, before I almost decided to reload Service Pack 2, I decided to do a little research first. Turns out that the file indeed exists and file permissions are correct.

Well, how did I fix it…. it was so easy I got scared.

You have to follow the path: C:\Documents and Settings\Administrator\Application Data\Microsoft\MMC

and fom there you can either rename or delete the file of the corresponding Snap-in. Use the profile of the user, which starts the Snap-in.

In may case I just renamed the “rrasmgmt.msc”  and then I was good to go. Easy, peezy!
