Thank you for the reply
i have previously reinstalled iTunes on the Acer and my iphone. It didn’t help.
i also tried restoring my pc system to a date when I am pretty sure it worked , but no success.
i am using windows defender firewall and avast free antivirus.
iTunes is Ain the list of allowed apps for the defender firewall.
I not sure why it appears in the list 3 times but each occurrence is authorised for private networks,
just to be thorough, I tried authorising all 3 for public networks temporarily, but remote still does not find the library.
I have reviewed and double checked the article. I haven’t missed anything as far as I can see. In any case it still works perfectly on my hp so the problem must be on the acer.
any other ideas would be greatly appreciated.
