Re: Ping Issue on Windows Server 2003

Just for the sake of completeness here ...

Further investigation shows that the MAC address entries under ARP -a 10.1.1.80 change between immediately right after the ping and when the server finally answers. Creating static ARP entries on the workstations for 10.1.1.80 solved the problem immediately (band aid solution).

The offending device was found to be a misconfigured firewall that someone introduced on the network. I have to locate and purge the incorrect ARP entries from our networking appliances, and that may yet take some time, but I feel I have things under control now.

The issue is definitely that there is "something" telling windows that .80 is unavailable on the network. Setting any NIC on any computer to .80 results in the "address in use" message.

So the address .80 appears to be in use somewhere on the network, excepts that I am unable to locate the device through pings or portscans. Can anyone offer any advice about tracking down the source to this problem?

I can force the server to use .80 as well, and the server eventually does respond to pings on .80.

As an update, I've determined that changing the IP address of the computer to 10.1.1.81 resolves the ping issue, but .80 continues to cause problems. Any ideas?

Could there be another device on the network with an address 10.0.1.80?

To test, disconnect the TS from the network (or disable the network
card), and ping that address from some other machine? Do you get a
response?
