You should try two things:
- Make sure to login with the Administrator account case-sensitive.
If your account is called "Administrator", then use an uppercase
'A' when logging in.
This case-sensitivity issue is a temporary workaround for a
potential security problem in OpenSSH. This will be rectified
with OpenSSH 8.0 which allows to login case-insentive again.
- If that doesn't help, switch the user running the sshd service from
"cyg_server" to SYSTEM (the services GUI calls it "LocalSystem")
Cygwin switched the logon method and this method doesn't run
under the "cyg_server" account sometimes. However, switching
back to "LocalSystem" instead of having to create a special
"cyg_server" service account is one of the advantages of the
new logon method. For details, see
