Hello,
Recently, I uninstalled SEP 12.1 from one of my servers and after the reboot I could no longer RDP to the server.
I also found that AD replication traffic was being blocked among others.
We disable the Windows Firewall service as a default configuration and are not doing so via GPO.
I found the only way to restore traffic flow was to enable the Windows firewall service again.
As soon as I disable it, the traffic is blocked again.
I have run Symantec's Cleanwipe utility and have tried restoring the defaults on the Windows Firewall but still don't have a remedy.
Does anyone have information on what SEP does to the Windows firewall config and how to restore it to it's default/previous configuration?
I was running SEP 12.1 <12.1.1000.157> on Windows 2003 R2 SP2 64bit.
Thank you.
