MMC – Active Directory

After a server crash at work I came across this error when trying to access active directory users and computer

MMC cannot open the file C:\WINDOWS\system32\dsa.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.

I tried a number of solutions but the only one that worked for me was to recreate the mmc file

If you have the same problem just try recreating the file

# Start

# Run

# MMC

# File, Add/Remove Snap-in

# Click Add

# Select Active Directory Users and Computers

# Click Add

# Click Close

# Click OK

# Click File then SAVE as

# Point the browser to C:\Windows\System32\

# Name the file dsa.msc and replace the existing file.

Try loading active directory users and computer and all should be OK

If there any other *.msc files that are doing the same thing, follow the same process but change accordingly
