SYMPTOMS

A DOS DCE (data communication equipment) RPC (remote procedure calls) client binds to a DCE RPC server and places a successful RPC call. The client will not place any additional RPC calls for a period of time. During this window of time, some RPC servers may close the connection. The next RPC call from the client to the server will fail. If the exact same call is placed again, after the failing call, it will work. The above pattern repeats indefinitely.

CAUSE

The RPC runtime is not being notified of the closed connection. Once the RPC runtime discovers the connection is closed by a failing call, it will establish a new session on the next RPC call to the server.

RESOLUTION

RPC runtime will now retry three times if a call fails. During the retry, the connection will be reestablished.
