Terminal Services over slow network

Hi

I am trying to run W2K TS from the UK to a country far far
away. This is using a 2Mb/s link but includes 2 satellite
hops. Are there known latency issues which would prevent
me from doing this?

Regards

Dan

Forgot to mention that If I visit the remote server and TS
from a local workstation to this server, all is okay so I
know the TS setup is fine it's just when I try to connect
from the UK.
 
Yes. RDP & ICA connections do not require a lot of bandwidth, but highly latent connections can make applications virtually unusable. What is the time on a ping from one side to the other

Citrix has made some improvements like Speedscreen, local text echo & mouse click queueing to try to help, but if it takes over a few hundred milliseconds for data to get from terminal server clients to the terminal server you may be in some trouble

Have you done any feasibility testing?

I am trying to get some testing sorted as we require a
satellite emulator but that's being sorted. The link
speed is 384kb/s of which the classification at which we
run has been allocated 85%of that. Within our
classification, there are numerous systems also running
including some which are voice rather than data. The
nature of the project I'm on, doesn't allow the install of
extra software without going through an exhaustive
integration, test and release process so that'll take
quite a bit of time and money. Is there a way you can
increase the timeout threshold thus allowing RDP traffic?
I also noticed that if I try to ping one of our remote
servers using a load of 14000 bytes and a 4000ms timeout,
I get a one in 20 loss with a latenct of between 1100-
1300ms. I have presented these findng to the customer who
are not convinced that these finding prohibit the use of
terminal services to remotely manage the servers in
question.

Once I can get the emulator combined with a link on which
we can drop the speed to around 128kb/s I'll be able to
prove the problem (he said).

Any thoughts?

Many thanks and aplogies for the long winded text.
