DFS Management Console Broken (Server 2008 R2)

Hey Everyone, hopefully this will be an easy fix; very shortly after installing SP1 on a Win Server 2008 R2 x64 machine I noticed that the DFS Management Console was broken. Error message pops up:

MMC cannot open the file C:\Windows\system32\dfsmgmt.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.

After doing some troubleshooting I'm finding that if I rename dfsmgmt.msc to something else, say dfsmgmt_original.msc it will open just fine. However, with the original name I get the error message. I have yet to find any other consoles that have an issue.

As a workaround I've renamed it to dfsmgmt1.msc and altered the path in the start-menu shortcut, but I'd love to know what happened in case I find any other issues that may or may not be related.

Thanks in advance.

This issue may occur when one or more of the .dll files that are used by the Microsoft Management Console (MMC) are missing or corrupted. These files include the following:
Msxml.dll
Msxml2.dll
Msxml3.dll

Try registering these files.

Hey agarwalrahul, my applogies for not replying sooner (I recall writing a comment, but I guess I never did post it!) Anyway, I've reviewed the provided link but was only able to register Msxml3.dll (the other 2 files were not found). There is no immediate change but the article does say a restart is required. I will have to wait until the end of day to give that a shot. I'll post my findings, thanks!

Ok, was finally able to restart that server and confirmed that the problem still exists. I still don't know what went wrong the first time, but I was able to get around it by using the workaround in the first question, so I am going to live with that answer for the time being. Thanks for your assistance agarwalrahul.
