Ipconfig /Release or /Renew Leaves NetBIOS "Computer Name 03" Unregistered

The NetBIOS "computer name <03>" name (as shown by the nbtstat -n command) may remain unregistered under the following conditions:

• After you first unplug the network cable (for a long enough period of time to detect a Plug and Play event, about 30 seconds), and then plug the cable back in, the NetBIOS "computer name <03>" remains unregistered.
• When you change the TCP/IP subnet (while the computer is hibernating, connect it to another subnet, and then wake up from hibernate on the new subnet) and run the ipconfig /release command followed by the ipconfig /renew command, ipconfig/release unregisters the NetBIOS "computer name <03>" name, but ipconfig/renew does not restore it.

Note This problem is intermittent and depends on the processor speed.
