Hi

I'm having a problem setting up some remote desktops. I
am a reseller & am trying to setup my customers for
remote administration. I have sucessfully set up 10 or
15 customers. 2 customers however are giving me
problems. Whenever I connect to these customers the
connection bar appears at the top of my screen but no
display appears. If I try to get into the Remote Desktop
Window I see the connection bar at the top of the screen
& everything else is black. After a few minutes the
Following error appears

"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"

needless to say when i try to connect again the same
situation arises. At all times i can ping the remote
server.

The setup is as follows.

My PC is running Windows XP Service Pack 1. Both servers
are running Windows 2000 Service Pack 4. I am connecting
over DSL thru a VPN to the remote sites. In one case i
am using the windows VPN client, in the other I am using
Sonicwall Global VPN client.

Both sites are setup for Remote Admin mode in terminal
services so i should not be having any licensing issues.

I have tried 2 PCs and a laptop here in the office & all
give the same problem. I am not sure where the problem
lies. Are there any hadware/grpahics issues with
terminal services ? I have just upgraded my computer to
the latest video drivers for its Intel 82845G chipset.
Again this did not help.

All suggestions / solutions would be gratefully received

thanks in advance

Sounds like a blck hole router problem. Check:

Q. Sometimes when I connect to my terminal server, I see a black
screen. Why does this occur?

A. This typically occurs if there is a device between the client
and the server that is receiving packets but not passing them on.
One way around this problem is to change the MTU size for the
network adapter that is being used as a terminal server connection
to clients.

Ethernet uses a maximum MTU size of 1500. You can start with 500
and then slowly move up until you notice the problem to find the
correct value to set
