Unable to Remotely Administer WINS Servers Across Routers

 Last reviewed: October 31, 1997
Article ID: Q174396
The information in this article applies to:
  • Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

SYMPTOMS

When you attempt to add a new Windows Internet Name Service (WINS) Server to your WINS Manager and it is located across a router or firewall, you may receive the following message: 

   The Windows Internet Name Service is not running on the target machine,
   or the target machine is not accessible.
NOTE: You cannot add this server using its computer name or its IP address. You have verified that the remote server is running WINS and that it is operating correctly; you are also able to communicate with it using Ping.exe (both by IP address and computer name) and you can connect to its resources.

CAUSE

Your router or firewall is not forwarding TCP Port 135 (Service Locator).

RESOLUTION

Contact the manufacturer of your router or firewall for information on how to enable the forwarding of TCP Port 135.
