Am a newby to windows Active directory. Installed Windows 2003 R2 enterprise 64 bit on vmware ESXi as a guest. Domain, DNS, DHCP roles installed based on typical settings. Similarly installed Win XP SP2 as a guest. Screen shots of DNS config and IP configuration of both server and PC enclosed. nslookup OK on server. But fails from the Windows XP . Please help resolve DNS so I can add the XP to the AD
