Question : Computer missing from domain listing?

On my office network I have added a PC to the domain and notice it is not listed in the Domain. The PC was set up the same manner that all of the other pc's on the domain and still it doesn't appear on the domain list. I can ping, connect to net resources etc. and can view the domain from the pc. Firewall is off, dhcp enabled, all of the usual protocols installed etc.

WHY? WHY? WHY?
