Why would an arp -a command return nothing on a properly functioning W2K system? The system is properly configured with IP it is able to browse the net, etc. I wonder why it is not returning anything for arp. It has a static IP address.

try pinging a few machines and then rerunning the arp -a command.

See if that adds some entries.

Are you sure? On my server, I had my arp command work just fine without pinging any one. Why would that be?

Well if you already have connections or had connections recently to certain machines through some other machines then the arp cache would have entries. This will ensure that new arp entries are added into the cache by pinging.

Is there more you needed for this. I don't feel that you finally did arrive at the answer you needed. Or did you?

I will try pinging, but I am not sure that is the solution.

Thanks

No, pinging is not the solution and that was what I was trying to say. Pinging is a troubleshooting tool that will hopefully manually populate the  arp cache. If it does not, then we can take it from there...
