WINS Entries Fail to Replicate to WINS Partner

• Microsoft Windows NT Server versions 3.5 and 3.51
• Microsoft Windows NT Server version 4.0

SYMPTOM

An entry or group of entries exists in a Windows Internet Name Service (WINS) database, but the entry or the group do not replicate to WINS partners.

CAUSE

There are two possible reasons:

• When an entry is added to the WINS database, it is added with an expiration date. This expiration date is calculated by taking the Computer date and time on the WINS server and adding the Extinction Timeout value. Once this entry replicates, the expiration date is compared to the Replicating WINS servers computer clock and if the dates are past those defined for the entries, the entries are removed.

  Example:

        WINS Server 1                       WINS Server 2
        Computer Date: 10/1/95              Computer Date: 10/6/95
        Extinction Timeout: 96 Hours        Extinction Timeout: 96 Hours
  
        QUAIL1(00) 10/5/95      ------>     Because the Extinction Timeout
                                            is now earlier than the Computer
        QUAIL1(03) 10/5/95      ------>     Date on WINS Server 2, the
        QUAIL1(20) 10/5/95      ------>     entries do not replicate.
  
     -or-
  
  

• If you modify the Extinction Timeout in the WINS Configuration, and set it to a time less than the value defined for a push/pull session to take place, it is possible for Timeouts to occur before the replicating takes place.

WORKAROUND

Make sure that the WINS Servers clock times are in sync, and do not modify the Extinction Timeout to less than the parameters defined for push/pull replication.
