I'm trying to connect to another IIS server and I know the windows firewall is turned on on both servers. I'd like to be able to create an allow rule, but what port does IIS 7 use to connect to another IIS server?
Sorry, let me be more specific. Using the IIS manager to connect to another IIS server.
If you are talking about Remote Administration (connect to another server using IIS Manager to manage it), then the answer is port 8172 by default using SSL. That of course can be changed on the server using the Management Service UI inside IIS Manager.
