WINS records that are flagged as tombstoned remain in the WINS database and are
replicated to any other WINS servers as part of replication cycle. After the
Extinction Interval has passed, the tombstoned records
are marked extinct and are cleared from the database by a scavenging operation
which occurs every Verification Interval. Queries for
tombstoned records are ignored. Tombstoning is the method to insure database
consistency in a WINS replicated environment.
