Terminal Services and Direcway Satellite

[pv]

Currently running W2K Server in a remote location on the Direcway 4000
satellite system. The internet is routed through Sygate Office Network. I
can terminal service into the server and perform all functions etc without a
problem.

When I use the DW6000 which is a stand alone satellite modem (next
generation) and a US Robotics broadband router, I have problems.

When I establish the TS connection remotely, the System process runs wild
and takes 99% of the cpu time effectively hanging my server. The only way
to recover is to hard boot the server. Clients on the internal LAN can run
TS sessions without any problems until I establish the remote session.

I have tried 2 different broadband routers, Linksys and the US Robotics with
no change. I have connected the server directly to the 6000 modem and the
same result, System takes 99% of the cpu and it's game over.

The DW6000 has a public static IP address and gives another public Static IP
address to the router or server (depending which is tied to the modem). The
DW4000 has a single public IP address which is then routed by the Sygate.

Any thoughts or suggestions or solutions would be greatly appreciated.

When you look at the process list, the System is using all
the processor cycles? Hmm...what service pack are you
running? And none of this happens when you use the DW4000?

Due to issues with our propietary software I am forced to use SP 2 on the
server (don't ask )

When I use the DW4000 system there are no problems at all.

That's most unfortunate. Could you possibly clone your
current terminal server, and then try installing SP4 just
to see if it works? If it doesn't work, you have tested
some alternate solutions.

If it is a hardware problem, then installing the SP will
atleast give us a little bit more information to go off of.

And just to tempt fate, what happens if you install SP3 or
SP4 on the machine? What exactly does the software do
that makes it incompatible with SP3 or SP4?

I will tempt fate and install SP4.

Issues revolve around install routines with our software and we do not have
the manpower to find the issues at this time. That I leave to the
programmers though.

I however need to find a fix for this TS problem and the DW6000.

Thank you for your help and suggestions. Once I have SP4 installed I will
let you know the results.

SP4 installed along with all patches etc. Same problem, system consuming
99% of the CPU

I have identfied thread 56 within the system process as the culprit. What
this means is beyond me.

VNC works and will be testing Radmin next. TS seems to be the fly in the
ointment.
