symantec endpoint protection 14.3 ru4 release notes

4103 build (for client and manager), which initially thought fixed it, but just made the time before it starts to slow down after a reboot, a little longer. Is there something different I should be doing with my firewall policy? I am upgraded to the latest. One this slowness starts to happen I can completely disable the client on the server, or just disable the firewall policy, and then all is well again. The other strange thing is that if I reboot the server, network speeds will be O.K for a few hours, and the bog down again. I can start moving files over the network and will tell me it is moving at a speed of about 12KB/s, If I open up my SEP manager and disable the firewall policy where ONLY the server resides, about 10 seconds later my transfer speed bumps up to 5-10MB/s. This is on a server that is a DC, and has Hyper-V running with a two virtual servers. I see night and day difference when I transfer data via network. I have narrowed down my problem to the firewall portion on the client on the server. But I don't believe that to be the issue in this case. First of all, I know that SEP can be a resource hog.
