I have a working configuration Manager 2012 R2 SP1 setup in an AD forest and now I would like to use the same environment to deploy software update (only) in non-trusted AD forest.<o:p></o:p>

 I tried installing the configuration manager clients non-trusted AD DC's but its not able to find the site server. I have already opened  required firewall ports such as 80, 443, 445, DRPC and 8530 & 8531 ports but still it can't find the Site Server.<o:p></o:p>

Can someone please point me in the right direction on how I should setting up Site Server to deploy software updates in non-trusted AD forest?

Cheers - Merwin

" but its not able to find the site server. "

Define and spell out in *technical* detail what the above statement means and why you are making it. If you are referencing log files, define which log files and post the entire unedited and relevant snippets in this thread. If you aren't using log files, then explain exactly what you are doing, click by click, step by step and how you are reaching this conclusion.

In a normal ConfigMgr environment, only port 80 is required from the client to the site but without more detail, nothing more can be said.
