Quoting "Fred J." :
Did you tried them separately, one at a time. This way you can find out if the
router and the W2K server are running DHCP.

hope this link will help with DHCP.

thanks for all you help

one point, which may or may not find help on this mailing list;
my w2k box Local Area Network which is setup for dhcp, I tried
many times to change from: Obtain an IP address automatically to: Use
the following IP address and then used
IP address: 192.168.1.104
subnet mask:255.255.255.0
Default gateway: 192.168.100
but when I hit Ok, and then go back to see it, it defaults back to
Obtain an IP address automatically.

I know I have to set my routing table, which I am working on and might
need to start another t heard to kindly ask for you help.
