Configuration:
Windows 2k8R2, MS SQL 2005 database, 2 SEPM servers at one site.
SEP 12.1 RU1
Number of clients: 9k+ of 12.1 RU1 & 11.0.X Clients
Problem:
The automatic LU that was runs daily, goes through a period where it no longer updates clients.
The information on the SEPM console shows 1/3 of the clients no longer has up-to-date definitions.
In the past Symantec support has had me reboot the SEPM servers.
This is not a fix but a workaround that doesn’t always work.
I found this article and look like a solution but didn't resolve the issue.
