Hi Jim,
JRemote is not involved at all in the process. I was only mentioning JREMOTE as I am able to access the library with authentication through JREMOTE without any issues - Media server on - authorization code entered on JREMOTE, user name/password entered - acsess to SERVER good. It is my understanding that you have to use authentication with JREMOTE in order for changes (rating changes) to sync back to the server.
The issue is with adding a new computer on my LAN - unable to access the media server without unclicking the authorization button on the SERVER computer.
In regards to your wiki recommendations:
As for the Network access issue - I ran the test connection and received an okay on the server computer. I also am familiar with setting up my router for port forwarding and allowing ports/ip address's through my firewall. - so firewall is not the issue - The server is on a new Windows 8 computer and maybe there is something that needs to be done specifically in Windows but I don't think so.
As for your Server issue - I have it set up as a library server -the use media library and set up dlna server box is checked. (although the wiki still references MC 16)
I was just trying to point out that with the authentication boxed checked and a username and password noted - when you go to the client and add library under playing now and enter the key from the server - it never connects - as soon as I unchecked the authorization required on the SERVER computer - the CLIENT on the LAN was able to connect. Seems like this is a bug.
