the netgear switch doesnt allow u to have an IP address on it, the netgear switch is that simple 5 -port switch (http://www.ebuyer.com/product/35437) <<link of switch im currently using. If the DC’s DNS is 127.0.0.1 then why cant i connect other XP computers to my domain..?
Your default gateway should be set to the IP address of the netgear switch or, better yet, your router. If this is the first Domain controller for the domain, 127.0.0.1 is fine, you can change it if you want. If it is a second domain controller, manually set the DNS address to your original DNS server.
You need to manually set the DNS address in your client machines to the server. Otherwise they don’t see the domain.
