5. Result: "The Windows Defender Firewall rule SMB Block Outbound is blocking your connection"

 

Is that controlled by Group Policy? I've read some post saying a user was able to convince his Admin to adjust GP so he can use ReadyShare again...

 

That is interesting, and probably the problem for you. I don't use Windows Defender for the Fireware, I have Norton ISS installed with does it.

Wonder if you ran some 'WannaCry" program that 'protected you against it and it made changes for you?

What you will need to do is open Settings for Windows Defender and see what rule is blocking port 445, and there could be others as well.

A lot of those are duplicate info mostly, but worth looking at them.

Better yet, before venturing down that path, why not just TEST with the Defender Firewall turned off and see if that is actually the problem?
