Clock Synchronization

Although the client and server clocks are originally synchronized, they can lose this synchronization. When this happens, the client RPC subsystem normally receives the RPC_AUTHERROR error message and should resynchronize.

A client can receive the RPC_AUTHERROR message even when the clocks are synchronized. The message indicates that the server's nickname table has been flushed either because of the table's size limitations or a server crash. To receive new nicknames, all clients must resend their original credentials to the server.
