I can't add any vista machine onto my domain. It's very odd.

we have dhcp, and it is getting an ip assigned to the vista machine, but we can't ping the dhcp server, we can't ping the active directory server.

When i ping the ad server it will get a reply the very first time and then request timed out every other time after that until i reboot.

If i do ipconfig /renew it tells me it can't find the dhcp server, but i know it can because on the server i see it has an address lease for the vista machine.

We have two domains, works fine on the other one. anyone have any idea what is going on?

This is odd, i can ping other computers on the network, just not the ad / dhcp server
