Description:
When Configuring the SQL Server APM for a Server that contains both SQL 2000 and SQL 2005/2008 you get the following error:
Unable to connect to SQL Instance.
Check that it is online and the login details are correct.
This SQL Instance will not be added for browsing until the above error is resolved.


Symptoms:
If both SQL Server 2000 and SQL Server 2005/2008 instances co-exist on a SQL Server, the SQL Server APM will display only the SQL Server 2005/2008 instances by default. In this mixed environment, to configure the SQL Server 2000 instances, you must first remove all SQL Server 2005/2008 instances from NVBU, and then add the SQL Server 2000 instances.
When adding back the Server 2000 instance, you will get the error:
Unable to connect to SQL Instance.
Check that it is online and the login details are correct.
This SQL Instance will not be added for browsing until the above error is resolved.
