Basically the solution follows, but you'll need to use regedit:
add the new key HKLM\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters\AllowInsecureGuestAuth key, value set to 1
It's interesting to know one of my other computers that works doesn't have this key, but it has "AuditSmb1Access" which set to 0, which this computer doesn't have.
Wanted to bump this up, after a ton of searches this was what fixed my issue. I had never edited a registry before, so I used this website to walk through it. It's easy after you read the article on what you are doing.
