What am I missing? I have a 2003 server, a swtich, and a PC running XP Pro. I setup AD on the server. Setup DNS (not sure if this is right and might be where the problem lies). Setup DHCP and activated it. I setup a user on the server with domain admin rights, and even setup a computer in AD with the clients PC name. The client PC does get the IP via DHCP, it can ping the server using IP and name. I put entries in the host and lmhost file and still I can't get the XP machine to connect to the domain...what gives?
