enable kde desktop on xdmcp

[itai weisman]

hi ppl,
I'm tryin to configure a RHEL server as xdmcp enable server, In order to use emulation utilities (such as reflection) to connect to this server (I need kde desktop).
no matter what I do, I can't connect to this server and receive a 'The specified XDM host is unwilling to manage. (RX2109)'
does anyone have any idea what it might happen?
any ideas?
Itai

[Alexander Chuzhoy]

Are there any messages in /var/log/messages ?

do you use XDM or GDM ?
Does a reboot help?

[itai weisman]

I prefer to avoid reboot... any other options?
I have some messages reagarding to X server.
I use gdm.
