I used rdesktop regularly at my previous job.  I had M$ Office
& Project documents to edit, as well as the occasionaly IE-only
Intranet site to use.  rdesktop, in my experience, is far preferable
to the Citrix client I used previously.

rdesktop is very fast, highly scriptable and flexible.

None of the scripts make individual directories for roaming profiles,
but if this would be helpful it can certainly be added.

The scripts (by way of smbldap-useradd) make a home directory for each

I just checked Dave's How-To (which ships inside the smbldap-installer
tarball) and his roaming profile are all stored in
/opt/samba/profiles, so that should work for other folks...

The danger with storing profiles inside the users' home directories is
that the users then have the power to delete or otherwise mangle them.
(And they're just sitting there like a big red button with a big
blinking sign - "Push Me!".)

If the smbldap-installer scripts should be enhanced to make this
easier for folks, just let me know what needs to be done, and while
I can't make any promises I can do my best to make this work better
for you all.

The real solution is to do what you've already tried - fix the problem
with DHCP not setting the gateway.

But you can do the following to hard-code the gateway on system
$ echo route add default gw > /etc/init.d/gw-hack
$ chmod 755 /etc/init.d/gw-hack
$ cd /etc/rc5.d/
$ ln -s ../init.d/gw-hack S11gw-hack

The above is how you can create your own startup-script to do anything
you want.  I picked S11 because network startup is S10, and you want
to set the gateway after the network is started.

Also note that if you have any machines that don't boot into graphical
mode, the "runlevel" you want is 3, so you should put startup scripts
in the rc3.d directory instead.  (See /etc/inittab for your default
runlevel, and further documentation of all this.)

Yeah - I'd chmod 700 instead - /sbin/halt, /sbin/shutdown, and
/usr/bin/consolehelper (which is symlinked from /usr/bin/reboot).

Ah - and see /etc/inittab (again) to change what happens when a user
gives the three-finger salute: "CTRL-ALT-DEL".  Just find the
ctrlaltdel line and change the command it runs.  (For example: rm -rf
$HOME... ;)
