Kodi on Fire TV constantly losing SMB access

I had everything set up and it was fine. I have folders on the computer downstairs that serves as a media center and data backup for my home network. It’s running Window 7 and I shared and set permissions and security for the folders I want to see to Everyone and Anonymous Login with full permissions to damned everything.

Two days ago, Kodi on my fire TV was able to see my shares. In fact, it was able to see my workgroup and browse around other shares I had as well. Today, nothing but errors. I click a share and it immediately says “Connection timed out”.If I browse for an SMB connection, It cranks for a while then shows double dots to go back a level and nothing else.

The computer downstairs is on and nothing has changed about the access. What kind of voodoo is this? What magic trick will make my Kodi stay connected to my network media?
