Thanks for the reply, yes the subnet mask I have is 255.255.255.0. It was the default, so I just left it. But all my clients on the network are internal to the same router, so I guess that would be good.
But I'm sorry: I edited my question a bit right before you answered. It might make it a bit confusing, but in terms of having the server acquire a stataic IP address, I was wondering if I should specify it from the DHCP role or from the TCP/IP properties page.
Thanks
