I have a long time domain member computer that I just took out of service due to an upgrade. I wanted to send it to another group of users, but when I went into computer management to change Local Users and Groups, it will expand properly, but when I try to enter the Administrators group, it returns and error "Interface Not Registered."
I went on to find that nothing in the MMC is accessible beyond the first tree level. For example, I can expand the Event Viewer, but not open individual events..
I reapplied SP3 hoping to freshen the activeds.tlb file that one forum suggests is the problem. The machine still runs well and logs into the domain with the users currently listed and no other applications seem to have problems. I just can't use the MMC.
