Docker on Windows File Sharing Blocked by Firewall

TL;DR

I believe that there was another anti-virus that was running that was causing the blocked firewall issue

I decided to switch from using Windows Defender to Norton Antivirus to see if that would resolve the issue. When I tried to install Norton it complained that it could not remove a previously installed version of the AV and the installation aborted. As far as I knew the only AV I had on my system was Windows Defender. There was no evidence of any other AV running in the system tray. I checked the services list - I found an entry for Norton but it was not running. I am not sure if that entry existed before or it was created as part of the unsuccessful installation. Either way, I rebooted by computer and decided to try sharing the drive again and it worked. I was able to ping 10.0.75.1 and share the c drive without issue. My best guess is that there might have been a version of Norton running in the background which got cleaned-up when I tried to do a fresh install and allowed the files to be shared.

I wish I had better insight into the exact cause and the fix but it is working now. Thanks.
