When logging on to VP1, the following error appears:

File: SQL Access ManagerSQL error. Stmt #: 2 Error Position: 0 Return: 404 – [Microsoft][SQL Native Client]TCP Provider: No connection could be made because the target machine actively refused it.

The MSSQLSERVER service was shut down on the database node. Restart it, and then log on to PeopleSoft.
