Sometimes Windows (specially 2003 Server) messes up when registering needed dll's to the system, ending in you getting error messages like missing dll's, or just that a snap-in for the MMC could not be initialized (in this case, the snap-in for the Enterprise Manager that comes with SQL Server 2000).
[Solution]
Register the missing dll's by hand, if they are on the HDD. If not, download them from Microsoft and place them to %WINNT%/system
In this case, the following command solved the problem:
Code: Select all
regsvr32 sqlmmc.dll
