Also if David is running PS 4.5 there is a known bug with sessions
disconnecting / reconnecting.
I had a call open with Citrix and got a private which then turned into
http://support.citrix.com/article/CTX113561 and then became a post Rollup 1 fix
http://support.citrix.com/article/CTX114104
There was also a Force Ping enhancement introduced in Rollup 1

Hi David,
Unless your comms people know about Citrix session reliability (ICA on port
2589) and have configured QOS etc to accomodate ICA on port 2589 instead of the
"known" port 1494, having session reliability enabled in your farm can lead to
a number of communications problems.
If the server hasn't detected that the session is disconnected, it won't
allow any additional connection by that user. So there are also a couple of
other things that need doing.
The default setting for your servers is to allow only one user session. You
can change this using the terminal server configuration manager utility (start
> run > tscc.msc) under server properties.
The Citrix farm has a property called the ICA keepalive timer. If the ICA
keepalive is enabled, this defines the interval at which the server checks to
see if the client is still reponding. Once the keepalive fails, the session is
tagged as being disconnected, and users will be reconnected to the sessions
they lost. The keepalive timer interval has to be short enough that the session
failure is detected (and the session disconnected) before the user tries to
reconnect or the connection will fail, as you're finding.
regards,
Rick

Hi list,
we've just installed a new farm, new servers as well.
Ps 4.5, 2003 MUI R2
also, we set up one web interface to connect to.
for some reason, we are having some disconnections randomly, and after
this occurs user cannot reconnect because the server doesn't accept more
than instance.
We are a bit confused about this because we have no disconnections
either a published app. or ICA/RDP protocols or user session in AD.
Anybody could point me in the correct way?
Thanks.
