INFO: RPC CALLBACK Attribute and Unsupported Protocol Sequences

MORE INFORMATION

If an RPC interface has a procedure with the CALLBACK attribute, it can only make use of connection-oriented protocol sequences. The following protocol sequences are not supported:

• ncadg_ip_udp
• ncadg_ipx

If an RPC client tries to call a remote procedure that in turn calls a procedure back on client, the client will be able to make the initial call, but when the server tries to call the procedure on client, the RPC run time generates exception 1726: The remote procedure call failed.
