Domain Controller Shows "Unidentified Network"

In some cases, a Windows Domain Controller may show a network connection as "Unidentified Network", even on systems with a single network connection. 

While there may be other factors that lead to this, I've found that it's often caused by a missing or incorrect DNS suffix on the connection.  Ensure that in the Advanced TCP/IP properties window, the "DNS Suffix for this connection:" box is filled in with the proper DNS suffix for your domain.
