Error 5 (Access Denied) and Named Pipes Provider error 40

Hello there,

I recently started having trouble with my local SQL Server 8.0 database server. When I try to start it with Enterprise Manager I get the following error:

An error 5 - (Access is denied) occured while performing this service operation on the MSSQLServer service.

Nothing showed up in the SQL Server error logs. If I try to connect to it using the SQL Server Management Studio that came with SQL Server 2005 I get the following (slightly more informative) message:

Cannot connect to (local) ... (provider: Named Pipes Provider, error 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 2)

I'm not sure which log to look at in the MSSQL folders: MSSQL.1, MSSQL.2 or MSSQL.3.

Furthermore, if I manually start the MSSQLSERVER service, then I can connect just fine with the SQL Server 2005 Management Studio but still get the weird error message with SQL Server 8.0 Enterprise Manager.

Any ideas?

Thanks

Nevermind, I figured out that I had changed the name of my computer. I changed the name back and can now connect to the server just fine.
