A System Center Configuration Manager 2007 site fails to upgrade to Service Pack 2 and reports SQL Error: The server service principal name already exists. You may also see the following in the Configmgrsetup.log file:
<MM-DD-YYYY HH:MM:SS> ***SqlError: [Microsoft][ODBC SQL Server Driver][SQL Server]The server principal '<Domain>\Server1$' already exists.
This can occur when a server in a site server role is renamed and the SPN's and SQL logins remain associated with the old computer name.
1. Remove the <Domain>\<OldServerName> login record from the Configuration Manager database using SQL Management Studio.
2. Remove the old Service Principle Name using ADSIEdit:
3. Add the new, proper SPN using the following command:
setspn –A MSSQLSvc/<SQL Server computer name>:1433 <Domain\Account>.
Note: See How to Configure an SPN for SQL Server Site Database Servers for more information.
4. Run SP2 setup again. This time it should complete successfully.
