Found the problem! Apparantly, when I renewed my ESET Anti-Virus license several months ago, the software decided to "help" me by installing a firewall on my MC Server that it didn't tell me about! Turned the firewall off and the web page popped right up.
Now that I've finally seen what the Web Interface looks like, I can't say that it looks very useful, though..
I have MC in the basement running three independent zones; front yard, back yard, and a 7.1 surround system for home theater in the basement. What I'm looking for is something I can put out in the front and back yards for remote control of the CD playlists and volume levels in the two zones when we are entertaining. I'm thinking something along the lines of a netbook would be ideal. I haven't researched this yet, but can one instance of MC running on one PC take remote control of another instance of MC running on another?
Probably ought to start another thread on that subject! Thanks again for all the help!
Best Regards!
