"Do you want iTunes to accept incoming network connections?"

Thanks pascalim. Though it didn't require all the steps you took, your post did point me to the errant .plist in question and I resolved it with the following:

In /Library/Preferences/ in found 2 copies of the com.apple.alf.plist:

com.apple.alf.plist (created today)
com.apple.alf.plist~orig (created May 29,2009)

May 29th was about the time I began experiencing this issue with iTunes repeatedly asking me if I want to allow incoming connections.

I trashed both copies and then rebooted the Mac. Naturally a new copy of com.apple.alf.plist was created and now the Firewall reverted to OFF.

Launched iTunes and was now NOT asked if I wanted to permit iTunes to accept incoming connections. At this point I quit iTunes.

Went back into Security Prefs and turned the Firewall back ON. Relaunched iTunes and was again NOT asked if I wanted to permit iTunes to accept incoming connections.

So it appears that simply trashing the com.apple.alf.plist and rebooting is sufficient to clear this issue. I had a feeling it was a .plist issue - I simply didn't know which one it was. Thanks again.

Unfortunately, my joy did not last. Though it appeared to have resolved the issue simply deleting the .plist in question was not sufficient to permanently resolve it. After another reboot, the problem came back.

I went back and performed all the steps you describe in your post above (including the Terminal command) and it still did not prevent iTunes from asking if I wanted to permit incoming connections.

so now I am back to square one. Thanks anyways. Any other suggestions would be appreciated.

ends up performing an Archive & Install of the OS and that cleared up the issue for me. Thanks for the input anyways. Cheers!

I have discovered why this is occurring for some users. Do you have an iPod or iPhone paired to iTunes as a remote? Even if you don't try the following:

Launch iTunes and click "Allow" when you see the alert box.
Open iTunes Preferences.
Click on "Devices".
Uncheck "Look for iPhone and iPod touch Remotes".
Then click "Forget All Remotes".
Close iTunes Preferences.
Quit iTunes.

Now relaunch iTunes and see if you are asked to allow incoming network connections again. If it has stopped, and you must use a remote, then try re-pairing the remote again and see if the alert appears again.

It appears that for other it is allowing iTunes to share music over the network and others it is allowing control of iTunes from remote speakers. So it may be any activity related to iTunes over the network that triggers this. Nevertheless, try the above with what ever setting is effecting you and see if it clears it up.

If it does reappear after reactiviating your preferred setting, then you need to report it via the following bug report page with as much detail as possible:

If it continues to remain as issue for you, ultimately, we may need to live with it until iTunes is updated or not use remotes until then. Hope this helps for some.
