3.2.5 Timer Events
Version vector request time-out: Upon a version vector request time-out, the server tears down its state associated with the logical connection. Pending asynchronous calls on the connection are completed with an error (ERROR_ACCESS_DENIED), and new calls that assume the presence of the connection object fail with the same error code as well.
Time-outs on open file handles: When a context handle is determined stale by a server, it closes all states associated with the context handle. Subsequent calls by a client on the context handle fail with ERROR_INVALID_PARAMETER.
