SYMPTOMS
When a computer running Windows NT 4.0 is connected through a router to another device on a remote network, and that router exchanges multiple ICMP REDIRECT messages with another router (which provides a new path for the computer running Windows NT to get the remote device), the route table on the computer running Windows 4.0 may grow unnecessarily.
CAUSE
This problem is caused by a problem with TCP/IP in Windows NT 4.0: TCP/IP would add the information about the new path to the route table, but did not delete the previous route, causing the route table to grow unnecessarily.
RESOLUTION
A new version of Tcpip.sys is available that corrects this problem and deletes unnecessary routes that are updated by redirect messages received from the router.
To resolve this problem, obtain the hotfix mentioned below.
STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
