I have an NT 4.0 domain. We our primary dns server is a Windows 2000 member server. Sometimes, when a client tries to connect to a host, the only way we can connect to it is by using the fully qualified domain name. Like when mapping a drive you have to type in host.domain.com. Other times, you can just type the host name. This makes no sense to me. Can anyone tell me what's happening and how to correct the issue?
