Greetings,
Recently strange problem with Remote Desktop appeared: Remote Desktop Connection hangs in "Configuring remote session" state, but only when I'm trying to reach "external" machine -- when I'm connecting boxes in "workarea" network -- connection goes without any issue.
The "problem" machine is under Server 2008R2 (with all current updates). And I can connect to some other 2008R2 in my workarea.
Same with client: all latest updates installed.
I can't say exactly when "this" started -- about a week ago.
I have TCP packets log:

so it's seems that connection attempt being made. But then, by some reason, it's being closed.
Can I enable "some" logging "somewhere" to troubleshoot this issue?
Best regards...
