Need help - samba updated and broke my shares

I have two boxes running the turnkey linux and they’ve been great, but exactly yesterday, both stopped responding to my samba shares that had worked for a year+ without problem. I’m thinking something got updated and now I need to know how to fix.

I looked at my smb.conf file, which even though it looks right, I noticed the last change was also yesterday. So i think something in there changed, but for the life of me, I can’t tell what!

Tried re-adding the root user (I do this as root so I can modify anything in the entire file system from my windows machine) using pdbedit and that didn’t do anything. Restart the server, nothing. Tried adding allow user and force user, nothing is working.

Any ideas? Thanks!
