Clients on our network recently started receiving this error when attemping to acquire an IP Address from our DHCP Server:

"the name specified in the network control block (ncb) is in use on a remote adapter"

The DHCP Server is a Windows Server 2008 R2 machine, most of the client are Win 7.

Can't find much on that error, anyone have an idea what could cause it?

This issue happen to us after migrating from 2k3 to a 2k8 DHCP server due to a stale dns ptr record with the old DHCP server. Make sure your DNS is clean after a migration! – user71739 Feb 22 '11 at 17:53

Two things to check

  • Do you have conflict resolution turned on for the DHCP server?
  • Is the DHCP server registered in AD

Try reconciling dhcp server (right click scope node, snd click "Reconcile"). Finish wizard, and try renewing ip on the computer having the issue.
