Renewing Wins Client Registrations with NBTSTAT -RR

MORE INFORMATION

Below are some situations where reregistering a WINS client's names would be necessary:

• 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.

A Microsoft WINS server record includes a WINS client's NetBIOS names, its IP addresses, and a value called a version ID. WINS servers use a client record's version ID to keep track of records that need to be replicated to other server. This allows new WINS records to be replicated without sending the entire database from one server to another. This version ID is incremented when new records are added, but not when they are renewed. By quickly releasing and renewing the record, an existing records version ID will be incremented.

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.
