WINS Replication Problem Events 4262, 4261, and 1c Replication

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

The following symptoms may occur:

• Replication or scavenging may stop if WINS should encounter either of the following events. Your Windows Internet Name Service (WINS) server may log one of the following events in the system event log in Event Viewer:

  
        Event ID   : 4262
        Source     : WINS
        Type       : Error
        Description: WINS got an error while trying to register a unique
                     replica with name <computer name>. The replica is owned
                     by WINS with address given below. 

  -or-

  
        Event ID   : 4261
        Source     : WINS
        Type       : Error
        Description: WINS got an exception while trying to register a
                     group's replica with name <group name>. The replica is
                     owned by WINS with address given below. 




• 1C records may show an expiration date of forever "-.-" after replication occurs to a replication partner. This may cause an access violation when using Winscl.exe to view records in a WINS database.

CAUSE

This problem may be caused by the following:

• WINS would stop replication or scavenging encountered a record that was in an unexpected state, for example the replica of a special group that has all members timed out but the state is not tombstone or a replica that is in the released state.



• WINS is modifying the record time-to-live (TTL) value during replication. The TTL of the name is set to 0xFFFFFFF resulting in the infinite expiration date.

RESOLUTION

A fix is now available that does the following:

• WINS has been modified so that, during replication/scavenging, if WINS should encounter an exception while trying to register a group or unique replica, the record will be overwritten, ownership will be determined by the most recent registration, and replication/scavenging will continue.



• WINS has been modified such that, when group members are unioned, Windows NT changes the ownership only if a bigger list is created. The time stamp for the record has also been modified to verify the interval instead of 0xFFFFFFFF, which resulted in the expiration date.



• There has also been a change to how 1C records are treated with migrate on enabled. In the past, after a 1C record was initialized as static, the only way to get the record back to dynamic was to delete the record on all servers and restart the servers. Now the record will be changed to dynamic if the owning wins server changes the record to dynamic.

MORE INFORMATION

The following WINS events 4262 and 4261 have changed from Event Type Error to Event Type Informational.

These binaries also fix a problem where, after replication occurs, the 1C list renewal interval is changed to forever "-.-" and may cause access violations when using Winscl.exe.

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
