MMC Could Not Create the Snap-in "DHCP"

Hi, we have a Windows Server 2003 R2 STD x32 SP2, this is our Domain Controller and suddenly it start giving us the error "MMC Could Not Create the Snap-in" When traying to open the DHCP Management Console, if I open another MMC for example GPEDIT.MSC it opens without any problem. I also try to open the MMC.EXE and  add the Snap-in manually but DHCP is not on the list. Any help will be appreciated. Thanks

Try reinstalling dhcp. You may have the tool installed but not the service.

If you get the following error while opening IIS,
MMC could not create the Snap-In
Then execute the steps given below to fix this issue.

1. Register the .dll files "mmcndmgr.dll" and "inetmgr.dll"
Commands:
i)  Start | Run | cd  %SystemRoot%\system32
Here, 'SystemRoot' refers to 'C:\Windows'.
ii) regsvr32 mmcndmgr.dll
iii) regsvr32 inetmgr.dll

Tips:   'regsrv32' is a command line tool to register the .dll in the registry.

2. Uninstall and Re-install IIS
To uninstall, Start | Control Panel | Add/Remove Windows Components | Check 'Application Server', click 'Details' | Uncheck  'Internet Information Services'  | Click 'OK'

To install, Start | Control Panel | Add/Remove Windows Components | Check 'Application Server', click 'Details' | check 'Internet Information Services' | Click 'OK'
Now you can access IIS without any error.

Hey it's worth a shot.

Actually every other MMC on the server is opening without problemas, the only one that gave the error is DHCP, so no need to work with IIS I think.
