SYMPTOMS

On a multiprocessor computer that is running Windows Vista or Windows Server 2008, a network connectivity failure occurs randomly when you run certain utilities, such as the Remote Shell (Rsh.exe) utility or the Remote Copy (Rcp.exe) utility. This problem occurs if a network application is using the same four-tuple (server IP address, server port, client IP address, and client port) every time that the utility reconnects a TCP session in a TCP TIME-WAIT delay period.

For example, consider the following scenario:
  • On the Windows XP-based computer, the Remote Shell service is installed.
  • On the Windows Vista-based computer that has multiple processors, the Remote Shell utility (Rsh.exe) is installed.
  • You use the Remote Shell utility on the Windows Vista-based computer to access the Windows XP-based computer.
  • The Remote Shell utility commands continue to run one after another for several minutes.
In this scenario, the Remote Shell utility may fail. Additionally, you may receive an error message that resembles the following:
Windows XP computer name: Operation timed out

CAUSE

On a Windows Vista-based or Windows Server 2008-based computer that has multiple processors, the TCP initial sequence number (ISN) generation method has changed. Therefore, if a TCP connection that uses the same four-tuple (server IP address, server port, client IP address, and client port) is reestablished in a TCP TIME-WAIT delay period to a remote host, the ISN that is generated for that connection does not let the TCP session continue. However, you expect the session to continue. For more information, see Request for Comments (RFC) 1337, "TIME-WAIT Assassination Hazards in TCP. To see RFC 1337, visit the following Internet Society Web site:

RESOLUTION

A hotfix is available to resolve this problem. However, not all the Windows Vista-based or Windows Server 2008-based multiprocessor computers need this hotfix. Only the computers that run the specific commands need the hotfix.

Hotfix information
