Another error encountered, another error resolved.
During the upgrade of the sample database, TWO, I received an error on the procedure SVC_MailProcessLOG. The error message was:
ERROR [Microsoft][SQL Server Native Client 10.0]TCP Provider: The specified network name is no longer available.
That incredibly helpful error message really means: Perform your GP Utilities run on the SQL Server itself.
I made the mistake of running GP Utilities from one of the client machines, not from the actual SQL Server. It appears that something in that procedure causes an issue when you’re trying to create it from a client machine, over the network, rather than from the local SQL Server itself.
Another good reason to RTFM, I guess
