Is getting a SEP 12 client to work (unmanaged and goes through a Blue Coat proxy server) more of a challenge than with SEP 11? Even with all of the proxy server URL exceptions specified in TECH162286, it appears every 12.x version I've tried thus far has difficulties downloading anything via LiveUpdate beyond the catalog listing.
For newer versions like the latest SEP 12.1.2, I usually first install an unmanaged client on a test VM to see how things go. The 12.x client not being able to update its virus defs from the get-go is very disconcerting to me. In contrast, unmanaged SEP 11 clients required no modifications on our proxy servers and worked straight off to get their virus defs. Yah...I'm still running SEP 11.0.5 in our environment and was hoping to upgrade to 12.1.2 since it's supposedly compatible with Win8 but this issue just makes me lose confidence in going further.
If an unmanaged SEP 12.x client has difficulties getting its virus defs, I wonder if the SEPM server will do any better? I would think many of you are running behind proxy servers for Internet access so figured I must be missing something in our environment. Just can't figure out what.
