The TCP session does not close until you run the "net session /d" command to delete the SMB session on the file server on a Windows Server 2003-based computer (887707)


The information in this article applies to:

  • Microsoft Windows Server 2003, Web Edition
  • Microsoft Windows Server 2003, Standard Edition
  • Microsoft Windows Server 2003, Enterprise Edition
  • Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems

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.
