When building the diminsions I can see the records in my database, however when I try to browse the dimension data I get this error:

Unable to Browse the Dimension 'Dimension Name'. Unpecified Error

I am running XP and am trying to connect into our SQL database & or my machine and get the same error reguardless of where the datbase is located.

Also about half the time or more when I use Analysis Manager to connect to a database I get the error:

Cannot connect to the registry on the computer 'MY COMPUTER NAME' or 'MY COMPUTER NAME' is not a member of OLAP Adminstrators Group

Which it is a member.

Any ideas, I'm very new to OLAP and need to use this PC to create cubes.
