PC not found in DHCP / WSUS

Hi everyone,

Recently I have Windows XP re-installed(and formatted) on a PC, it's working fine and I can login to the domain as per normal, however I'm unable to find this PC under DHCP>Adress Leases.  But I can see the "Computer" in Active directory users & computers.

Also notice that it download Windows update from internet instead of WSUS(as the speed is slower).

Tried delete and re-create the computer in AD(with same name), take it off from the domain then assign to work group, restart, bring it back to domain, but still doesn't help.

The PC is able to browse network drives, outlook working fine(exchange is on site).  But with VNC, I can only connect to it with IP address, using the computer name does not work.

Any suggestions?

    Do you have your TCP/IP settings configured to register with DNS?  Go to the properties of your NIC.  Open the properties of TCP/IP.  Advanced button and then the DNS tab.  Make sure the checkbox for "Register this connection's addresses in DNS" is checked.

    Hi amichaell,

    Found out that the issue is caused by duplicated computer name on the network.  There was another machine using the same name, so I created a new computer in AD and problem solved.

    And the "Register this connection's addresses in DNS" option is checked.

    Thanks for your help!
