Can't Get XDMCP Login on Mandrake 9.0 Box from XP

Well, you were right, when I had logged out of the automatic login, the kdm
was running.

However, I still am unable to get a login prompt from the XP machine using
"xwin -query [mandrake] -from [xp]".  I still only get the blank X windows
screen with the "x" cursor.

Also, I just spent 30 minutes looking at every possible configuration
program/menu option for dealing with users and login, and the only option I
saw for automatically logging in was unchecked.  But, it does automatically
log me in.

Harold, you've been really responsive, and I certainly appreciate that.
But, I must also say I'm surprised that these tools don't work better with
one another out of the box, so to speak.  I guess I'm just spoiled by

If it takes me this long to get this working, just think how long it will
take to set up Samba, mail servers, web servers, database, etc.

Thanks again,

The mistake you made while installing Mandrake 9.0 is to tell it to
automatically log on a certain user when the machine starts up.  Since that
is the case, no display manager needs to be running until that user logs

When the graphical login prompt appears, press Ctrl+Alt+F1 to get to a
console, login, then run the ps command.  Press Ctrl+Alt+F7 (I think, maybe
F8) to get back to the graphical login.

There should be some sort of Mandrake configuration utility that will let
you tell it to stop logging a user in automatically on startup.  Look around
for that.

Well, I did both the ps -e and the ps -A, and neither showed any "dm"s
running.  This after a cold reboot.

When the Mandrake box boots up, it goes right to the KDE desktop.  When I
log out of that, it drops to a console type view, then, after a moment, goes
to a graphical login prompt that says "Welcome to [machine name]" at the
top, and has options for user/pass, session type, a menu option to restart
the x server, and a shutdown option.

I'm using a straight install from the Mandrake 9.0 ISO images, and I tried
to select every possible package during the setup process.

I just assumed that kdm would be running, as if it were some underpinning of
kde.  Remember, I don't know anything about Linux!  I have used eXceed in
the past to log into Sun and IBM unix boxes, so I understand the process,
although that was almost 10 years ago.

How do I get the necessary services running correctly?
