A universally unique identifier (UUID) uniquely identifies an interface on a remote procedure call (RPC) server. After these interfaces are defined in an RPC protocol definition, you can then use the definition in a server publishing rule, to allow clients requesting RPCs on the RPC server to access procedures identified by the UUIDs.
If you know the RPC server on which the interfaces are defined, type in the server name or browse to its location. You can also choose to enter UUIDs manually, without specifying a server. If you choose to define interfaces manually, you can later specify the server address in the server publishing rule.
