I know that someone recently asked a very similar question, but I tried all of the answers that showed up under that question, and nothing seems to have worked for me.
I am trying to set up Home Sharing between two computers. One is running Windows XP, the other is Vista. I do not have a firewall installed, and I do not believe that I have a router firewall.
The two computers are mine, and my girlfriends. I made sure that her computer was authorized to my account, and I authorized my computer to her account. I have tried setting up the home sharing thing using my account information, and using her information, and each time, the sharing icon disappears, and nothing happens. I've verified that both computers are set to check for shared libraries, and I've made sure that both computers are set to share their libraries.
I've tried restarting Itunes after enabling Home Share, and I've also tried restarting both machines. Is it just not possible to share between XP and Vista, or is there something that I may have missed? When I check under preferences, I can see that sharing is on, but there are no users connected. I'm at a loss as to what else to try. I have made sure that both computers were actively running Itunes, and double checked that neither computer was sleeping, and nothing has helped.
