BUG #: 52892 (SQLBUG_70)
If the cluster group that contains the SQL Server virtual server is takenoffline, you cannot successfully change the Microsoft Windows NT account information under which the SQL Server service runs.
WARNING: If you do attempt to change the account information (such as account name or password) while SQL Server is clustered, the service fails to start when you try to bring the cluster group online.
With the cluster group offline, any attempts to change SQL Server serviceaccount information cause the password to change but not the accountname. As a result, the SQL Server service fails to be validated byWindows NT security, and thus cannot be started successfully.
How to Change SQL Service Accounts on a Clustered SQL Server
The proper steps necessary to change the service startup accounts for a clustered SQL Server follow.
Make sure that the SQL Server Virtual Servers resource group is owned by the node on which it was initially installed.
Run the Cluster Failover Wizard and select the option to remove the SQL Server Virtual Server.
Change the service accounts for the MSSQLServer and/or the SQLExecutive or SQLServerAgent to the accounts you want. This account must be a valid domain account and should be in the local Administrators group on both nodes of the cluster. Also, the account must have the following rights:
Act as part of the operating system.
Logon as a service.
Run the Cluster Failover Wizard to add back the SQL Server Virtual Server.
Microsoft has confirmed this to be a problem in SQL Server 7.0.
