Can't connect with FaceTime on Mac

Question

I've just downloaded and installed the FaceTime on Mac beta on my three network connected home computers.
Everything works fine on two of the computers. I can make calls between two of the computers and I can make calls both to and from my iPhone 4 to these two computers.
But the third computer on the network is unable to send or receive a FaceTime call. I can find no differences between the System Pref settings among the three computers.
This is the console message I get from the problematic Mac:
10/20/10 4:54:39 PM FaceTime[1070] attribute = {
shouldFindExternalIP = 1;
10/20/10 4:54:51 PM [0x0-0x72072].com.apple.FaceTime[1070] PairUpCandidate: iLCCount = 2, iRCCount = 2
10/20/10 4:54:58 PM FaceTime[1070] * __NSAutoreleaseNoPool(): Object 0x118127df0 of class NSCFData autoreleased with no pool in place - just leaking
10/20/10 4:54:58 PM FaceTime[1070] * __NSAutoreleaseNoPool(): Object 0x11811f6e0 of class NSCFData autoreleased with no pool in place - just leaking
Can anyone make sense of this? Any ideas how to fix it?
Thanks.

cmearns,
It does sound like we have very similar problems with perhaps ultimately the same solution.
My situation may be a bit unique, however, in that all my testing is on and between computers connected to the same LAN, my home network. I have now installed FaceTime on Mac on four Macs connected to this network. Three of the Macs all work fine in terms of being able to send or receive FaceTime calls between themselves and from and to my iPhone 4.
My frustration is that the fourth computer on my network cannot complete calls to the other 3 computers or to my iPhone. Nor can it receive calls. When placing FaceTime calls from this computer, the receiving computer (or iPhone) recognizes an incoming FaceTime request. However, clicking the accept button never completes the connection. As far as I can tell there is nothing unusual or different about the setup of that computer. It is on the same network with the same sharing set up, etc.
Something happens at the final connection process that causes the call to fail.
