Why is RPC Server Unavailable?
An RPC server may be unavailable for a number of reasons. If the service that a client is attempting to contact no longer exists or has been moved to a different location, the RPC server will appear unavailable because it cannot fulfill the client’s request. Another reason an RPC server may be unavailable is that the network is experiencing hardware or software-related difficulties that must be repaired before the RPC server can be contacted. Likewise, a user may have disabled the RPC server or specifically prevented remote clients from contacting it.
How to Fix RPC Server
In order to fix an RPC server, the user must identify the problem that is causing the RPC server to be unavailable in the first place. The user should check all network cables, restart all network devices, and, if possible, manually check the RPC server for malfunctions and accessibility restrictions.
