The key here is to understand the difference between what happens between
synchronization and reporting. The reason your upstream server shows that
replicas have not synchronized is because the *reporting* is failing. The
replica server cannot report a successful synchronization until *after* that
synchronization has actually completed successfully. This is a function of
reporting.

This is generally a normal condition, and is a function of the time delay
between when the client computer reports to the replica computer, and when
the replica computer reports to the upstream server, and when the upstream
server actually processed that queued reporting data into the database.

Of course, if the replica server is not reporting correctly, then this
information will also be compromised, but in an of itself, it's not
indicative or conclusive of anything specific.


The thing to do is review the %ProgramFiles%\Update
Services\Logfiles\SoftwareDistribution.log for issues encountered by the
replica servers during the reporting events.

Also review the IIS logs on the upstream server for the same time block to
determine how IIS is handling the reporting connection requests coming from
the replica servers.

Finally, also review the Application Event Log on the replica servers.
