Where to Find Documentation

This document describes the issue(s) solved by this hotfix and includes installation instructions.

All product documentation is available from the Citrix Web site at http://www.citrix.com/support.

Issue(s) Resolved in this Hotfix

1. In an environment that allows only one instance of an application per user, attempts to reconnect to a disconnected session might fail, displaying the error message "You already have an instance of this application open and are not allowed to run more than one instance."

   [From PSE450W2K3021][#164054]

2. Disabling the Session Reliability feature causes the following error messages to be logged unnecessarily after the server restarts:

   Application Log:
   Error 100: An internal server error occurred with Reliability Server.

   System Log:
   Error 7024: The Citrix XTE Server service terminated with service-specific error 1 (0x1).

   [From PSE450R01W2K3003][#161195]

3. After disabling logons from a command line ("change logon /disable") and later enabling them again ("change logon /enable"), servers fail to be load balanced and do not accept ICA connection attempts. This happens even though such servers are listed in the list of available servers when using the command qfarm /load.

   [From PSE450R01W2K3003][#164584]
