Steps in the KB : KB01428 - Error retrieving the current PI server time. -10733 PINET: RPC Resolver is Off-Line
Generic "RPC Resolver is Off-line" messages can happen for a variety of reason. Typically, the error suggests that a major subsystem is not running which could include PI Archive Subsystem, PI Network Manager on the client or server, or in very rare circumstances the PI Message Subsystem. I would first ensure that you can retrieve values locally on your PI Data Archive and verify that the noted subsystems are running on that machine.
