Routing problem on Server
Posted on 2004-08-06
2 servers with same config on same subnet. One can get to LAN and Internet. Other can only get to LAN... No Internet.
I noticed that on the routing tables for the problematic server, a bunch of the metrics are 20... that doesn't seem right. Isn't that the expected amount of hops?
Here are the outputs of a ROUTE PRINT command on the servers. The problematic server is the first one.
How can I fix it?

the metric is the administrative cost - the lower the metric the higher up the packing order the route is chosen
So then why would these two servers show the different metrics? Are you saying that this is not my Internet access problem?

no its not the problem - metrics come in to play when multiple routes to the same network are available - the server chooses the one with the lowest metric first
Crud, so do you have any suggestions on my problem?
2 servers with same config on same subnet. One can get to LAN & Internet. Other can only get to LAN... No Internet.

In the Advanced TCP/IP Settings is the Automatic metric enabled on the Server/Nic with the 20 metric?
Things to check on the machine that has problem to the net:
1. Ping www.yahoo.com (see if DNS works or not)
2. Check you IE connection settings, make sure you are not running through a proxy
3. Make sure your router allows this IP address to access the internet (might be blocked)
let us know the error to #1 and also the error when you try to access www.yahoo.com from IE.

I like shad0's general direction. To that, I think it might be helpful to post the ipconfig/all from both machines. Helps fill in the overall picture....
In addition, would like to see the ARP table of the router, if possible

What are the MTU settings of the two machines? Is there any router config specific to handling of either address?
