Duplicate Route Not Removed After Second Redirection (164595)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q164595 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
