I have 8 servers running and had to do some maintenance on the dedicated machine they are running on. So I closed my servers, rebooted the dedicated machine, restarted my LFS-servers but 3 of them won't start. Is says "Status: Offline". I rebooted the whole server again but without any luck. Maybe there's a connection still hanging around on the master server and should it solve it self after some hours but right now I'm puzzled.

Hmm, sometimes you must think before you do something. Made a big mistake in the config-file which was causing the problem. All solved now.
