error when trying to open IIS

Archived from groups: microsoft.public.win2000.advanced_server (More info?)

Hello,
I have a server with Windows 2000 Server (Upgraded from Windows NT) and I
have the IIS intalled on it. First, IIS was working perfect, untill
something wrong goes with the server so I did a repair from the CD and then
it is up again. When I tried to open IIS it gave me the following error:

Unable to enumerate web sites because the following error occurred:
Object already exists.

I did all the steps provided on this page:
support.microsoft.com/default.aspx?scid=KB;en-us;q246459
but still didnt work and having the same error. I logged in as administrator
on the local machine and it worked successfully, so I think there is
something with the administrator account on the domain but have no idea
about it, if anyone can help me on this it would be highly appreciated.
Thank you.
