SYMPTOMS
On a Microsoft Windows Server 2003-based computer, you open files from the network. These files are still locked after you log off the client computer. If you examine the Transmission Control Protocol (TCP) sessions by using the netstat command, you see a TCP session that is similar to the following: File server: TCP   xxx.xxx.xxx.xxx:445     xxx.xxx.xxx.xxx:3572    CLOSE_WAIT Client: TCP   xxx.xxx.xxx.xxx:3572    xxx.xxx.xxx.xxx:445     FIN_WAIT_2 The TCP session does not close until you run the net session /d command to delete the Server Message Block (SMB) session on the file server.



CAUSE
This issue occurs because of a problem in the Tcpip.sys file. This problem causes the TCP session to remain open.
