Error opening Enterprise manager.

When opening SQL Server Enterprise Manager, I get the following error.
A connection could not be established to SERVER.
Reason: Invalid attribute/option identifier.
Please verify SQL Server is running and check your SQL Server
registration properties and try again.
I checked the registration properties and its set for windows
authentication. I'm logged onto the server as administrator.
For a bit of background information, recently the server was failing to
boot and I had to repair the Windows 2000 installation. My customer
reports that this problem has only occurred since then.
Any ideas/help will be gratefully accepted (Sorry, i'm a SQL novice).Is it possible SQL Server isn't running? Or that Enterprise Manager is
trying to connect to an instance that isn't running?

All instances appear to be running correctly.
As for the other suggestion (Julie) - I can't get as far as looking at
the startup parameters.

this problem David? You wrote that you installed MDAC 2.8 but was it the onl
y
thing you did. What about sqlsrv32.dll?
The system went down after a big thunderstorm so i was thinking if this may
be the cause of the problem....
