Event id 1864 Task Category Replication

Occasional Visitor

I have replace old DC 2012R2 with new two DC 2019

It's all work fine, and also replication but in event viewer i find, all day, ad error event id 1864 with this:

This is the replication status for the following directory partition on this directory server.

Directory partition:

This directory server has not recently received replication information from a number of directory servers. The count of directory servers is shown, divided into the following intervals.

More than 24 hours:
More than a week:
More than one month:
More than two months:
More than a tombstone lifetime:
Tombstone lifetime (days):

Directory servers that do not replicate in a timely manner may encounter errors. They may miss password changes and be unable to authenticate. A DC that has not replicated in a tombstone lifetime may have missed the deletion of some objects, and may be automatically blocked from future replication until it is reconciled.

To identify the directory servers by name, use the dcdiag.exe tool.
You can also use the support tool repadmin.exe to display the replication latencies of the directory servers. The command is "repadmin /showvector /latency <partition-dn>".


I control dc diag and repadmin /showrepl and it's all right can anyone help me or have any idea?
