“iTunes could not connect to this iPhone / iPod or iPad because an unknown error occurred.”
In some cases, restarting a Windows computer affected by this problem gets iTunes to successfully connect to the Apple Device. However, the real problem begins when a simple restart does not fix this issue. If you were not able to resolve this problem by restarting your Windows computer, the following are the two solutions that have proven to be the most effective against this problem:
Solution 1: Reset your Lockdown folder
The Lockdown folder is a hidden and protected folder present on all computers that have iTunes installed on them – including Windows computers. The Lockdown folder contains all kinds of temporary data, mostly pertaining to the syncing of your Apple devices with your computer’s iTunes. A solution to this issue that works for many people affected by it is resetting your computer’s Lockdown folder by deleting it. Don’t worry – once you delete the Lockdown folder, it will be reset and recreated almost immediately. To use this solution to try and get rid of this problem, you need to:
Solution 2: Uninstall iTunes and all of its components and then reinstall it
If Solution 1 did not work for you, there is another highly effective solution that you can use – uninstall iTunes and all of its components and then reinstall it. Uninstalling and reinstalling iTunes, as tedious a process as it can prove to be has managed to fix this issue for the majority of iTunes users who have been affected by it. However, it should be noted that you can’t simply uninstall iTunes by navigating to add or remove programs in the Control Panel and uninstall it. You are going to have to perform quite a few steps in a specific order in order to successfully and completely uninstall iTunes from your computer so that it can be reinstalled from scratch.

Phase 3: Reinstalling iTunes
Once you’re done with phases 1 and 2, you will have successfully and completely removed all traces of iTunes and its related components from your computer. To download the installer for the latest version of iTunes, click here and, when the website loads, click on the download the latest version link. On the next page, click on the Download now button and your download should begin. Once you have downloaded the installer for the latest version of iTunes, launch it (by navigating to and double-clicking on it) and go through the iTunes installation wizard right up to the very end. After the installation of iTunes, you should no longer be met with error code 0xe8000003 whenever you try to connect your iPhone to your Windows computer.
