In Service Pack 4 for Windows NT, a new feature has been added to the Windows NT version of the utility Nbtstat.exe. The -RR parameter will allow Windows NT clients to release their NetBIOS names and reregister them with their WINS server.
- The registration has been lost or deleted in WINS and needs to be refreshed by the client. Nbtstat.exe -RR will send a release and renewal of all NetBIOS services associated with the WINS client, creating a new record.
- The registration exists in some WINS servers but not in others. A reregistration is useful here to increment the WINS version Ids, which will help in causing a WINS server replication to occur.
When you run Nbtstat.exe -RR, a timer is invoked so the command cannot be repeated for 2 minutes. This is to prevent a WINS server becoming saturated by client renewals if this process is repeatedly invoked on a server.
NOTE: The -RR is case sensitive.
