What protocol? VNC (screen sharing), AFP (file sharing), SMB (Windows CIFS/SMB file sharing), ssh (remote command line login)? Other?
Do you have other accounts on the Mac mini? Have you tried any of those?
For the protocol in question, does the Mac mini System Preferences -> Sharing -> xyz service -> permissions section allow access?
Have you looked in the /var/log/secure.log ?
The /var/log/system.log ?
Looking for any related messages at the time the connection attempt was made.

system.log has lines like:
server AplleFileServer: received message with invalid client_id 2534
and late comes out with:
server servermgrd: PAM: Unable to authenticate.
server emond: Host at 127.0.0.1 will be blocked for at least 15 minutes
that repeats several times.
in secure.log I can't tell if previous attempts are there, but I tried again after making note of time stamp and nothing is added to it for almost an hour.
