I suggest - carefully searching all process deny rules in case Windows silently added a deny rule for the sshd process (yes, I've seen this happen) - adding a blanket allow rule in your Windows Firewall for tcp/22 from anywhere applied to all domains as a test. If either/both of these resolve the issue, make a better firewall rule for your use case. Also be aware that Windows Firewall rules for processes/binaries also do some kind of validation of the file itself, so upgrades often break it because the file that was allowed has been replaced and the replaced version needs to be manually allowed again. -- Erik -- -- "I do not think any of us are truly sane, Caleb.
