SQL Server 2008 is showing the SQL Server 2000 Version Number

We've got a server with SQL Server 2008 installed, but if we run:

SELECT @@version

or, as per http://support.microsoft.com/kb/321185:

SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')

the version number is reported as 8.0.2055 - I'm pretty sure that the server used to have SQL Server 2000 installed but was upgraded about a year ago.

Has anyone come across anything like this before? If so, how do you get SQL Server 2008 to report the correct version number?

• Are you certain you're connecting to the right instance of SQL Server? It sounds like your server has two instances (one under SQL2000) running.
