Okay, I've had it with this thing. It's now a complete mess. Maybe with all these details someone can figure out what's wrong:
1.Two servers: the original is HSAV1, the new one is HSAV2.
2. The two servers are replicating.
3. The Management Server List (with HSAV2 as the primary) has been assigned to all groups.
4. The servers are version 12, and the clients are all version 11. I created a package using HSAV2 and deployed it to the clients.
When I shutdown the HSAV1 server, the vast majority of the clients (600+ out of the 800 deployed) show as OFFLINE when I view the Endpoint Status window on HSAV2 management console. When I turn HSAV1 back on, they gradually come back to the "ONLINE" status. Why they are not looking at the new server I have no idea. Shouldn't the clients update their SYLINK.XML file automatically when I deploy the new package or because they are assigned it in the MSL?
Also, dozens of the clients that are ONLINE have an icon that looks like a downward-facing orange arrow and a red X. I assume this means they are disabled for some reason.
I'm working with 800 systems in 9 remote locations. There's gotta be a way to fix this without going to every system and reinstalling or replacing XML files.
