Vista Networking Problem [Server is 2003]

Hello,
I am having problems with vista computers. They can' t take IP address automatically but they often work if IP is given manually. I tried many tips i found on the net, including disabling power options of the NT cards, disabling IP6 n the like. Their DHCP Client service works fine and well, everything seems to work. How can i make Vista computers accept IP address auto from a 2003 server? All other windows work fine.

THANKS,

SAM

They do not accept them. They have to ask a server for one and be granted an IP assignment. Is the DHCP Server service running on the the Win2003 Server? Are the NICs on the Vista boxes configured to use DHCP? If so what happens when you type ipconfig /renew on one of the Vista machines?

I am not sure abt the NICS thing. But my DHCP Server is Windows 2003.
