CAUSE
This problem can occur if a Layered Service Provider (LSP) has been registered by using a Winsock catalog and the socket is canceled. Because of a thread synchronization problem, Winsock occasionally tries to free memory structures two times. In particular, you may experience this problem if Citrix Metaframe is installed and many users log on and log off by using Terminal Server sessions.
