Hi all,
I've been working on this one for a while, and I really hope someone can help.  
The problem description and notes are below:
Problem Description:
Users across WAN connections are being disconnected from their Citrix sessions 
with varying frequency.  Users are reporting that they are usually performing a 
file operation like opening an Office file or saving a document.  Some users 
are being disconnected when they start up an application that is tied to a 
backend DB.  All the DB servers and file servers are located in the data center 
with the Citrix servers.
- For some users, this happens once a week, while others report 2-4 disconnects 
per day.  Most users report somewhere between those two.
- Farm is MetaFrame XP FR2 with SP3.  Clients are either 6.30 or 7.1.
- Does not seem to be server specific, although clients have identified servers 
that they feel are better than others.
- Disconnections don't seem to be application specific, except for the 
DB-related disconnects, which can only be one application.
- Users receive the "trying to reconnect" message from the Citrix client only 
part of the time.  Other times (an almost equal amount) the users receive no 
message at all - the application just disappears.  In either case, the PN icon 
in the system tray flashes as if it's lost its connection.
- Sometimes on reconnection, the users will receive a message saying that they 
already have too many instances of the applications running.  This usually 
happens when they receive no "trying to reconnect" message.  The server shows 
the session state as "active."
- Users in the same location as the servers do not have any problems.


Thanks in advance,

Gabe Knuth
