I need a bit more info, but this might help. (probably not. I don't know if its authentication of a user trying to log on to the server, or the logonserver.exe and ascent\antrix.exe trying to talk to each other.)
in ascent.conf (or antrix.conf) find this line:
<LogonServer DisablePings = "0"
RemotePassword = "CHANGE_ME_LOGON">
and in logonserver.conf find
<LogonServer RemotePassword = "CHANGE_ME_LOGON">
and change that to anything you want, as long as they are the same in both. like I said, this is probalby not your problem, but its all I know of, unless you are using mangOS, then its a database thing.
