I had exactly the same issue – purchased ATV yesterday to add to my iMac with Time Capsule WiFi network setup. ATV connected perfectly to the Web but I could not get it to sync with my iMac’s iTunes library. I wanted to stream rather than sync but couldn’t do either. Tried all previous suggestions – PRAM resets, Firewall to “Allow all incoming connections”, router changes – all to no avail.

Console utility was reporting in its logs that my iMac was denying the ATV access.

I’m lucky enough to be friends and neighbours with an excellent network admin who deals with Macs as well as PCs but we still couldn’t figure it (I’m an SQL DBA so know a little about networks too). He also has ATV and streams with no problem and had no installation or configuration issues.

We wirelessly connected my ATV to his iTunes library and it worked first time, streaming like a dream. This ruled out ATV as the issue and put my iMac completely in the frame; we still couldn’t coax mine into accepting comms from ATV.

Finally tried the NoobProof freeware utility. I used it to specifically set port 3689 to “Allow” i.e. wipe out any existing settings and set the damn thing to “Allow”. Bingo. Everything now works.

It could be something I’ve done over the past 18 months since I switched to block that port so I cannot point blame at the iMac or ATV.

Now it’s working I have to say I think ATV is just superb, another quality product from Apple (I didn’t think that way about 24 hours ago though!).

Take-away: if you’re still getting the 3689 error then please try the NoobProof util (or something similar like WaterRoof) to at least rule out a genuine firewall rule is blocking the communication.

I hope this helps someone – when I was tearing my hair out I found plenty of reports of this problem but not too many suggestions. Please write how you get on and any success you have with this really frustrating problem. Best of luck.

Thank you, I’m glad you found the tutorial helpful.
