A little background first:
Starting at a company and they currently use Symantec Endpoint Protection Manager within Microsoft System Center. They recently overhauled the network and switched to a different IP scheme. There are roughly 100 machines that need protection and nearly 30 servers.
Issue: For some reason, this network change (or something else) has caused nearly 80% of the clients to disappear from withing the MSSC Console. I see clients from both IP scheme's in the pane's. . .and some are duplicated as well. If I go in to the SEP Manager Console, and navigate to the Clients button, not only do I see more machines, I see several more groups. Having said that, there are still many machines that are showing up when I search for unmanaged clients as well (Both Unmanaged, and Unknown). When I deploy the software to one of the machines (mine), it tells me that the deployment was successful, but the machine never gets added to the group, nor is the software showing up on my machine. However, if I deploy the software from the Remote Client Install portion of the System Center Console, the machine will show up in that group, and the software gets installed. It's quite confusing to me.
So, here is what I'd like to do. Overhaul and reconfigure everything (properly) so that all the clients are showing up in their correct groups on both Consoles. Short of redeploying and rebuilding the entire environment, is there a tip or suggestion that can be had to possibly figure out where the (literal) disconnect is? I'd like to avoid tearing everything down if I can, but will do what I need to do to make it right.
