Get netbios name from mac address

If the name does not exist in the database, then it is considered to be a new name registration. The time stamp is calculated based on adding the value of the Renew interval which by default, is 6 days set on the WINS server. A Positive Registration Response is sent back to the device with a TTL value equal to the time stamp recorded for the name on the server.

How network works - How computers become part of a network.

If the name does exist and has the same IP address within the database then there are two options:. When a client shuts down, it sends a Release Request to the Server. A Release Request is also sent when the nbstat -RR command is issued. The Server also sends a Release Confirmation message to the client. If the client does not receive a Release Confirmation message, then it may broadcast the Release Request.

This is also called the Renewal Interval and defaults to 6 days. If the server does not respond the client usually increases the rate at which it sends the requests. If the client does not renew its name within the renewal Interval then the server will release the name. Name Resolution in a Windows environment generally follows this sequence of steps:.

Statically mapping names to addresses is useful for clients that cannot communicate with WINS servers. Static mappings remain in the database indefinitely and do not age out or get replaced, even if the client attempts to update the name associated with that IP address. Static mappings can be removed manually, or they can be migrated to Dynamic entries by use of the feature Overwrite unique static mappings which allows to update a static entry with a new name.
