Remote Desktop via VPN - black screen

[mobief]

Since a couple of weeks I have a problem with remoteDesktop via VPN. A
while ago it just worked, but now it isn't anymore.

The situation:
pc with broadband at home
servers & desktops with working Remote Desktop at work (with working I mean,
it works IN the network and I have set up a couple of users/passwords to
login)
VNC viewer works (for the pc's where it is installed on - otherwise you can
say, just use THAT)
pinging to the host computer also works
XP sp2 installed (hosts & guests)
at home : no domain
at work : domain

When I try to start up Remote desktop, and I click connect after filling in
the IP address (I already found out it does not work with pc names), I get a
black screen (in full screen mode) and the computer is blocked. Then I get
a message : "the connection to the remote computer was broken. this may have
been caused by a network error. Please try connecting to the remote
computer again".

Now I think it has something to do with portforwarding, but I shouldn't know
how to configure IF it is a portforwardingquestion. My router is a Topcom
WBR 244

Thanks in advance !

Note: I also found a similar (the same) question on
http://www.eggheadcafe.com/ng/microsoft.public.windowsxp.work_remotely/post676863.asp
but there was no answer....

it could be MTU issue. quoted from http://www.chicagotech.net/troubleshootingts.htm
Black screen while connecting to TS

Cause: MTU size may be too high.

Thanks Robert !! I read the link and it's really possible that that will solve my problem BUT... In my MMC , there 's nothing to find about "terminal services". Please tell me I can find it at the XP cd ! Otherwise I have to install this feature with the cd of Win Server 2003 (at work)... if that's legally?

by the way... if I open MMC and I choose for "Remote desktops" there, I CAN ACCESS THE HOSTcomputer !!
But if I try it with rdc, it doesn't work.

I still have to find the MTU configuration....

Thanks again...

I found PPPProtocolType, ProtocolMTU and Protocoltype under the NDISWAN-parameters, but no TunnelMTU (which I added now)

See what it does now...
