I open regedit, click file->Connect Network Registry. I enter the name of the domain controller and check the name, then click OK. The name comes up in the regedit tree with HKLM and HKU hives listed. So far so good.
But when I try to expand the HKLM key, I get "HKEY_LOCAL_MACHINE cannot be opened. An error is preventing this key from being opened."
I can do this on one of our other domains just fine. Any suggestions what the problem might be?
