Have you seen this?
Published Applications Do Not Appear in the Citrix Management Console

Issue
Published applications don't appear in the Citrix Management Console.
Cause
A published application is an executable that calls another executable and
then terminates (for example, to publish the Citrix Management Console, you
publish Ctxload.exe, but the executable that stays running is Javaw.exe) and
the user already has a session open with another application that is used by
only one executable (that is, Microsoft Word uses only Winword.exe).
The Citrix Management Console tracks the executable that is published, in
this case, Ctxload.exe. Because Ctxload.exe calls Javaw.exe and then unloads
itself from memory, the Citrix Management Console thinks that Ctxload.exe is
no longer running and stops displaying that information.
Steps to Reproduce
1. Publish Notepad (\WINNT\notepad.exe).
2. Publish the Citrix Management Console on the same server (\Program
Files\Citrix\Administration\ctxload.exe).
3. Open Notepad as a published application.
4. Open the Citrix Management Console as a published application.
Under Sessions you see only a session for Notepad, but under the executables
you see Notepad.exe and Javaw.exe.
Resolution
This behavior was originally by design.
For MetaFrame XP, install Post Service Pack 3 Hotfix XE103W2K056 or its
equivalent and apply the registry changes outlined below.
MetaFrame Presentation Server 3.0 and Presentation Server 4.0 includes the
fixes introduced in MetaFrame XP Post Service Pack 3 Hotfix XE103W2K056, but
the registry changes below must still be applied.
27. If a published application was a program that created a new process and
then terminated itself, the published application appeared in the Citrix
Management Console. However, in a seamless session the application was
launched through session sharing, the application appeared in the Citrix
Management Console but then disappeared.
By default, the thread that checks the process cares about only the first
instance of the launched process. The thread regarded the published
application as terminated when the first instance of the process was
terminated even if that process created a separate process.
This fix provides a way to configure those published applications to use the
JOB object so that additional processes created by the initial process are
considered as published applications.
For this fix to work properly, you need to perform the following steps:
If the command line of the published application is [ApplicationPath], go to
the following registry key and make changes as necessary:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\Start
InJobObject
Key Value: [ApplicationPath]
Type: DWORD
Value: 0
. For example, if the command like specified for the published application
is c:\notepad.cmd, go to the following registry key and make changes as
necessary:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\Start
InJobObject
Key Value: c:\notepad.cmd
Type: DWORD
Value: 0
For those applications whose command line is specified in the
StartInJobObject key, the published application will not disappear from the
Citrix Management Console until all of the processes created by the process
are terminated.
[From Hotfix XE103W2K056][#63894]
Note:
If the path to the script that launches the application contain spaces, such
as c:\program files\test.cmd, add quotation marks around the Key Value:
"c:\program files\test.cmd"

Subject: [THIN] Applications Listed in the Presentation Server Console
Hello,
Has anyone run into an issue in which the Published application does not
appear in the Presentation Server Console. Only those Published
Applications that launch a script/batch file seem to be affected.
I found a similar issue in the archives, but that was for XP FR3/SP4 Rollup
1. This environment is PS4 Rollup 1.
Thanks,
Joe
