SYMPTOMS

Connectivity between a client and a non-Microsoft server message block-based (SMB-based) server may stop working during heavy data transfer periods.

When this problem occurs, the following error message is recorded in the event log on the client:
Event 3013: The redirector has timed out a request to SERVER1

CAUSE

On the client, the TCP window size reduces to 0 and it can no longer receive data from the server. The problem occurs because NetBT does not pick up data packets from the TCP driver.
