I am having a network of some 150 computers. One Windows 2003 server is running as Active Directory, DNS and DHCP.
I have joined 31 computers to the domain. But then now am not able to join any more.
The error message is
A domain controller for the domain XXX could not be contacted.
Ensure that the domain name is typed correctly
If the name is correct, click Details for troubleshhoting information.
I can ping the dns server with its name with the domain extensions, but when I try to ping with the name only, it says cannot find host.
