Nathan, I read your post because I am having a strange problem, server-manager is accessible on my local network but not via internet
All the files/directories match your listing BUT access.incl is missing from my system.
My default website loads, but \www.mysite.com\server-manager\ returns the permissions message.
I don't know when this developed as the system has only recently become a gateway, before that it was just a development server.
My virtual domains all required a tweak using server-manager to give global access, but I can't find anything on how to do this for server-manager!
All suggestions welcome
thx
mike
