There are three of us. A, B, and C. A is using an iPad2. B and C are using 2011 macs with 10.6.8. A can connect to B, B can connect to C, but A cannot connect to C no matter who initiates the request. Get the not available message. I checked all names and e-mail addresses on all three devices. They are correct.
