While troubleshooting a replication issue with my domain controllers today I've been puzzled by several questions that came into my mind and to which I don't currently have answers. Please help me clarify the following:
I have a script that daily reports the repadmin /replsummary ... information and the delta shown in those reports were usually between 1m-58m (including yesterday, 10/18/2022) but today the reports started looking differently (the reports from domain controller KM02, host names have been changed for the picture):
Q1) How come the today's delta is >60 days for KM02 (and also for VM-DC-01) if this delta was only 52m yesterday? I thought that if the problem - for example - has appeared yesterday (10/18/22) at ~10AM then the delta can't be more that 1 day... ???
Q2) Doesn't it look strange that there's a DNS lookup error for VM-DC-01 in the Source section but no errors in the Destination section of the report?
Q3) The main theory question: this article says:
Summarizes the replication status for all domain controllers that a given destination domain controller replicates from. This parameter does not display the source domain controller.*
- as far as I understand it means the term "given destination domain controller" in this case is KM02 (the dc on which the script runs), and if I'm correct then I don't understand how to interpret the presense of KM02 in the Destination list: it means KM02 replicates from KM02? What am I missing here?
Thank you in advance,
