Active Route keeps adding itself

[cherisc]

Hello,

We run IIS 5.0 on a Windows 2000 Server with the latest updates. I had to rebuild the server a couple of weeks ago after a crash.

After the rebuild, we noticed that people who had the same ISP as us were unable to access web pages on this server, they were not able to ping it successfully, either. However, they could access our mail server which is on a different 2000 Server and IP address, but it is in the same network.

After much troubleshooting, we discovered that the routing table on the IIS Server had an Active Route entry of:

Network Destination: xx.0.0.0
Netmask: 255.0.0.0.
Gateway: same IP address as the Server
Interface: same IP address as the Server

Using the Route Delete command, we removed the route and people were then able to access the web pages on the server.

Our problem is that when the server is rebooted, the active route is added to the table, and we have to go in and manually remove the route.

Does anyone know of a way to stop this route from adding itself, or even how it gets there?

Thank you in advance...
