tried quite a few combinations. here is how to re-produce the problem. the issue is with remote desktop session.
reboot computer from within remote desktop session. the "admin" instance shows as gray and offline.
login via remote desktop to admin account, then logout. now can connect to login screen via remotely.
another observation.
inside remote desktop session, turn off "start with windows" kills the remotly_boot_svc.exe process. but turn on "start with windows" does not stat the remotly_boot_svc.exe process. at this point, if reboot from within remote desktop session, the "admin" instance shows offline.
then, remote desktop to admin account, then logout, "admin" instance shows offline again.
Go to console and login to admin account, then remote login to admin account and logout from admin account. Now, remotly can connect to the login screen.
