Folks I'm having the same issue! I'm in Phoenix as well and I think I have narrowed the users who are being effected down to a link coming out of Wisconsin. This has been going on for a couple of weeks and one of our main providers is AT&T.

We are having a very similar issue here in phoenix...
Our remote locations through out he southwest are dropping connections about
every 10- 30 min. for the remote locations we use AT&T as well as Quest.
Its driving me crazy... Our corporate link is Air band. I can't seem to track down the problem. These links have been running for
2+ years and this is the first time we have had a consistent problem like
this.
I have adjusted the icakeepaliveinterval down and the tcpmaxdataretransmit
up and that seemed to help. Went from a 30sec connect to the 10-30 min
connect.
If anyone has any additional input, any at all I would be most grateful...
Wes

Might be experiencing a DoS. Contact AT&T, they should be able to monitor, find the culprits, and take action for you.

I may have to give that a try. I would like to have a packeteer here permanently but they are too expensive.
I have been watching the traffic monitor on my firewall and I noticed that there are a lot of denied inbound ping and dns connections about every five to ten minutes. A lot as in a hundred or so.
I wonder if those might be momentarily freezing my internet connection causing a disconnect.

Greg,
One thing I might add to the QoS solution is to evaluate a Packeteer
PacketShaper. This box can give you the visibility you need to help
identify and possibly fix your WAN Citrix problems (you get
visibility
on how the client is connecting, performing, and at what speed they
connect). Most of the time it isn't ICA, but rather other
applications
competing for the bandwidth. Evaluations are free, so you might as
well
give it a try, if not to only see what's going on. Also, you won't
have
to change ISP's in order to do this and you do not need a box at
both
ends. Only on the side where the Citrix Server Farm is located.
Check
it out at www.packeteer.com
Best regards, Randy

Greg,
Look at your connection to the internet both at the provider side (citrix server) and client side. Are all your users that are having problems going through the same provider? Has anything changed as far as your connection to the INet goes with the Citrix server? Have you run any tests are logging software to track the performance on both ends? These are some things I would look into. We have several customers that are expiriencing intermittant problems due to the ISP they have chosen. No way around it other than working with the ISP (not a great chance as they are trying to do things as cheaply as possible) or go with a better QoS ISP.
Hope this helps a little.

To: thin@xxxxxxxxxxxxx Subject: [THIN] Disconnects
lately, anyone connecting to my citrix servers over the internet has been experiencing a lot of disconnects. It happens to people running WinXP, Win2000, WIn98 etc. All clients are feeling the pain. It also happens to nFuse users, users with Program Neighborhood, and users with a custom .ica file.
It happens the same way every time, it happens to me too so I know my users aren't crazy (at least not this time). While working along typing or whatever, the session just appears to freeze. Nothing, completely dead. If I click the close button and click yes to disconnect and then reconnect, I am right back where I was. I just can't figure out why the session dies in the first place. It has been working fine for well over a year. It has just been the past month or so that it began doing this.
I do have TCPMAxRetranmissions and ICAKeepalives setup. I am running WIn2kSP2, MF XPa SP2/FR2.
I have been trying everything I can think of but still nothing so maybe someone can help me out with a fresh angle to attack this from.
Thanks!
Greg
