Endpoint Protection Small Business Edition

Hi Guys,

we are testing SEP 12.1 now. On all the test PCs, the live update cannot work well.

The log is as below:

Error LiveUpdate encountered an error: Failed to resolve LiveUpdate server name (0xA100000D). 

We are using Bluocoat as web  Proxy  and Microsoft TMG as application proxy.

Mithun Sanghavi,  

I can run live update when I am out of company internal network without error. So I assume it is proxy issue. How to enable debug log for SEP12? Maybe we can see more information in the debug log?
