Netgear Firewall/Router (this has been changed from a DSL Modem that
included a firewall/routing device...no change in behavior.  I have
noticed, after dinking in the registry, that under the
hklm\system\ccs\control\citrix\defaultclientconfig <--something like
that which is similar... All the values that I had changed in the
connection manager, i.e. timeout, disconnect, etc. was still set to
inheret from the client.  This was not so in the manager.  Therefore, I
change the keys to reflect the manager.  This might help??? Or I just
broke the crap out of my client's server!!!  We'll see...

What type of device is doing the Nat on the client side?

Interesting thread... I'm having an issue where client's will access a
desktop session through the web to one of the servers in my farm through
the firewall with a .ica file. It works great - but everyone in a while
a user cannot establish a connection and gets the 'citrix server
unavailable error'
- When it is because several other people are in remotely with out
issue. I have actually received the error myself - try a different
computer in my house - I get right in.=3D20

Very strange. I am wondering if it has to do with NAT...

Open to suggestions..

Are the clients using a many-to-one NAT?

They are running NAT on between two locations.  I.E. they have two
firewall/routers that connect each respective location to highspeed DSL
Internet connections.

HELP...

Ok, got that out of my system.  The story has change a little bit and I
am sinking waist deep into this Citrix stuff.  So, I went to the
client's server and ran the connection configuration manager
(mfcfg.exe).  Set it so no sessions should be dropped, etc.  The
situation at my client's remote offices has gotten better (they aren't
getting booted off after 5 to 10 min. of inactivity...now it is taking
something like 15 to 20 minutes).  I have looked at the client side as
well and edited the appsrv.ini changing the mouse and keyboard time outs
from 0 to 300 per an article I found.=3D3D3D3D3D20

Does anyone else have any ideas to help this Citrix Idiot get by???  I
am just getting my feet wet here with Citrix, however the similarities
between TS and Citrix are there (not extremely close, but the knowledge
of TS has helped out some).  So, with that mouth full said, what can I
do to make these remote offices work correctly?  They have a solid
connection via DSL to their home office (384KBps bandwidth for three
users).  So, please help me!!!

Short time is about 10 to 15 minutes.  I believe it is caused by the
timeout built into the client for licensing purposes.  On this
particular ICA Client, I cannot figure out how to change the timeout to
more.  Articles refer me to a cfcon.exe or mfcon.exe file...the
configuration program for the client.  This program doesn't exist on the
clients I am looking at.  Any ideas???

Can we get a definition of short? IS it consitently the same time period

Right.  But he said short periods of inactivity.  I took that to mean
seconds rather than minutes, but that could be coming from my own
situation where that was the case.
