Selecting "Advanced Settings" and then "incoming rules", I see one rule 
for sshd private: enabled, allowed and one rule for sshd public: 
enabled, allowed. There is a third rule for sshd domain: (disabled, 
allowed). I believe that one is irrelevant but I enabled it anyway, 
which did not help.

Is there someplace else I should look? This is Windows 7 Home Premium.
