Thanks on the Async, forgot myself. As for Outlook, it is more than
OWA, it is also the ability to access the organizations applications,
etc.
We are in the process of piloting the PS4/AG/AAC now, but do not see
that platform helping in the bandwidth department.

Hi Steve,
No, you're quite correct, no async support.
XP/Win2k was the last time we used a modem and I just plain forgot it
had been dropped on Windows Server 2003 :-(
I'd have to agree that for Outlook and IE, running IE natively and using
OWA makes a whole lot more sense than using ICA. If they need to view
documents etc in a more secured fashion then Access Gateway and Advanced
Access Control might be a good fit.
regards,
Rick

Correct me if I'm wrong, but didn't Citrix drop async with 3.0? You'd
have to setup a XP farm to provide direct dial-in.
But as Steve pointed out, why not just use the web? If all they're
accessing is Outlook and your intranet it'd be easy enough to do with
OWA.
With both low bandwidth and high latency, there really isn't any way to
give them decent performance.

You know, I had forgotten about this kind of connectivity. Had
not done it in so long, kind of old school, but you are right, it would
help cut out just a little more overhead. I seriously do not think that
our security team would allow a server with modem attached on the
network, but I forwarded the idea to management just the same.
Thanks!

Hi,
On a low bandwidth connection, you basically have to turn off
anything that generates additional noise.
If you're using an in-house or custom application make sure it
doesn't do unnecessary screen repaints etc that can't be cached in the
bitmap cache.
Turn off clipboard mapping 'cause this can majorly chew up
bandwidth on any WAN link. Make sure keyboard/mouse queing is enabled
because this will reduce the TCP/IP packet overhead.
Simplify things as much as possible.
Speedscreen addresses higher latency fairly well but the smarter
aspects won't really help you unless the local text echo etc can be used
for your applications. In Australia you can approach Citrix to see if
SpeedScreen can be tweaked for a particular application so that might be
an option for you.
You've also got an alternative for dial-up connections which is
connecting directly to a modem attached to a Citrix server. With direct
dialling you haven't got the overhead of supporting ICA over TCP/IP so
the session is generally a whole lot more responsive. However then
you've got an international telephone connection charge which may not be
acceptable.
regards,
Rick

These are for a few dozen users in undeveloped countries with
poor infrastructure.
I have done:
Enable SpeedScreen - Done
Lower both your resolution and color depth - Done
Disable audio - Done
Disable port mapping - Was looking at this, citrix policy in
MPS 3.0?
If they don't need to print, disable printing. - Was looking at
this, citrix policy in MPS 3.0?
Maybe look into a packeteer type unit for your home site. - For
dial up connections?

wow, and being CDC you are the guys that really need
communications.
Just some thoughts:
Enable SpeedScreen
Lower both your resolution and color depth
Disable audio
Disable port mapping
If they don't need to print, disable printing.

Subject: [THIN] Bandwidth Question
We have users in "undeveloped" countries, where
telecommunication systems are questionable at best, that connect at
dial-up speeds in the 15k to 20k range. These users connecting to our
Citrix environment complain that our "system is useless" :-p
it is my experience and opinion that you need at least 20k for
Citrix, ideally 26K.
Is there "any" ideas on how to handle these users over a crappy
connection?
