When you try to add a Windows 2000 Professional or Windows XP Professional computer to a domain, you receive:

The following error occurred when attempting to join <domain name>. The network path was not found.

03. Select Internet Protocol (TCP/IP) and press Properties.

04. Press Advanced.

05. On the DNS tab, press ADD and type the IP address of a DNS server and press ADD.
