WINS replication issue - periodic replication not occurring

Hi,

I have 11 servers at 11 locations in my organization. 1 is a PDC/WINS
server and the other 10 are BDC/WINS servers. All of them are Windows NT 4.0
SP6a.

The PDC/WINS was recently replaced (the old PDC/WINS was retired after being
replaced by this new server). This new PDC/WINS server will not perform a
periodic replication. I have found that as records change at our branch
locations, the change never makes it to my PDC/WINS server. If I force
replication manually, the records are updated as I would expect. After the
manual replication, reviewing the event log on the PDC/WINS server yields
some informational events (4237,4239, and 4121).

Event ID 4237 - WINS could not get the update count from a PUSH record (10
entries - 1 for every branch WINS server)

Event ID 4239 - WINS could not get the time interval from a PULL record (10
entries - 1 for every branch WINS server)

Event ID 4121 - WINS''s Replicator could not find any records in the WINS
database. This means there are no active or tombstone records in the
database. It could be that the records being requested by a remote WINS
server have either been released or do not exist.

Examining the statistics page in the WINS manager on the PDC/WINS server, a
periodic replication time never appears. On every other WINS server, this
updates regularly based on the default configuration of WINS. WINS
resolution works at every location and manual replication successfully
updates records throughout the organization.

I'm not sure what to look at next. I would appreciate any advice you can
provide me.

Thanks.
