We've configured our group policy to allow users to offer remote assitance to other suers to make it easier for users rather than them having to submit e-mail request etc. But we've just recently discovered that port 135 needs to be open in order for the expert to be able to offer assistance to the novice. I can understand this (I think) seing that the first thing it does is open that remote assistance window saying Joe Bloggs wants to offer you support etc. so I presume it uses RPC to start this process remotely.
However, if a user requests support it via e-mail or via file port 135 doesn't need to be open even though that same dialog box appears - it just require 3389. Likewise, how come Remote Desktop doesn't require 135? Escentially what we want to do is leave the policy in place but be able to do it without port 135 if possible. But first I'd like to understand why it's required
