NetBT Error 4321

I am receiving the following NetBT error 4321 on all of my computers in one of my domains:


The name"PAG   :0" could not be registered on the interface with IP address 192.168.10.121 . The computer with the IP address 192.168.10.142 did not allow the name to be claimed by this computer.

192.168.10.142 is the statically assigned IP address on a Netgear WNDAP350 Access point with DHCP disabled.  All of my workstations are wired.  If I unplug the access point and reboot several of the systems, the error is gone.  Plug the access point back in, reboot and the error returns.  This is a small domain that I manage and I know without a doubt I don't have any duplicate machine names or IP's on the network. I've found evidence that WINS was configured at one time on a file server but I can't find any evidence of it running now.  If I run nbtstat -n on a random selection of computers they all return similar to below:

U:\>nbtstat -n

Local Area Connection:
Node IpAddress: [192.168.10.121] Scope Id: []

    W-PAG-001      <00>  UNIQUE      Registered
    W-PAG-001      <20>  UNIQUE      Registered

Other than the occasional "duplicate name on network" popup, this error doesn't cause any access or performance issues.  My users can access their mapped drives on the domain, they can access email, surf the internet, etc.  However, its driving me crazy because I can't figure out what is causing it.  I don't believe errors are benign and eventually this might come back and cause problems.

My DC, old file ('WINS) server, Terminal Server, and mail server are all Windows 2003 32 bit.  I deployed a new file server in November which is Windows 2008, R2, however I can trace the Net BT 4321 error to the Friday night that I deployed the Netgear device.

Any input to keep me from the rubber room would be appreciated!
