Recently had a need to create a Windows 2012 R2 VM and proceeded to install the SEP client (12.1 RU6 MP6) as I normally would using a package I previously created and have successfully used in the past. However, it failed to connect to my SEPM server with an "HTTP error 407" under the client's Connection Status. The Last Attempted Connection shows my SEPM server name/IP along with 80 for the port number. Last Successful Connection says "Never".
Looked at another existing W2012 R2 server with 12.1 RU6 MP6 which is connecting just fine using port 8014. Thinking that perhaps our 2012R2 VM template might've become corrupted, I created another VM and installed the OS from scratch but the SEP client behaves the same way and fails to connect. I even moved the VM to a different ESX host thinking that maybe something's goofy with the networking to the host but got the same result.
SymDiag reports the following error which I don't see on the known working SEP client I mentioned, above. Again, I've used this same SEP client package to install on other servers before so don't understand why it's not working now. Thanks in advance!
