I think it's quite clear then: if you run the domain script on startup
without checking if WPKG client is already present, then the WPKG
Service and the Domain Script run simultaneously ...
IMHO WPKG service normally checks, if wpkg.js is already running, and
does nothing then. These are the majority of machines ... But if WPKG
service is running first, and then your domain script, it doesn't check
but just starts wpkg.js with your parameters.
I see. I imagined something like this also. I had excluded it only because
it does not happen on every machine.

Yes that's clear too, since it's perhaps a timing problem if WPKG
service or domain script starts first.
I think you have two options
- just delete/deactivate the domain script, since wpkg client has been
deployed to all machines probably in the mean time, or
- use a script which first checks if %programfiles\wpkg\wpkginst.exe is
present, e.g. wpkginstall.cmd containing
if exist %programfiles\wpkg\wpkginst.exe exit 0
\\serverip\WPKG\wpkg.js /install:WPKG_Client /quiet /nonotify /noreboot
I think this could be enough.
I created a file called wpkg_client_install.cmd and put it into a
\\serverip\wpkg\software\wpkg client\.
The file contains the following lines:
if exist %programfiles%\wpkg\wpkginst.exe exit 0
\\192.168.1.2\WPKG\wpkg.js /install:WPKG_Client /quiet /nonotify /noreboot
How can i see if it's working? I have tested it on my pc, but my pc was one
of the pcs that did not have the issue.
And, in the meantime, i have one more question: how do WPKG parse the
hosts.xml and/or the optional hosts folder?
I have created a hosts folder, thus i have modified the hosts.xml file under
\\serverip\wpkg to contain only the following lines:
================================
<?xml version="1.0" encoding="UTF-8"?>
<wpkg>
</wpkg>
================================
I then created a hosts folder \\serverip\wpkg\hosts in order to better
manage the hosts and the profiles related to the hosts.
I created a file called "WPKG_Client_hosts.xml" (to tell WPKG to deploy the
client in the startup script we are discussing) that contains only the
following lines:
==========================================
<?xml version="1.0" encoding="UTF-8"?>
<wpkg>
<host group="Domain Computers" profile-id="WPKG_Client" />
</wpkg>
=========================================
I then created a second file called Incredibuild_Agent_hosts.xml (in order
to try a silent install on my pc only) that contains the following lines:
=========================================
<?xml version="1.0" encoding="UTF-8"?>
<wpkg>
<host name="MYPC" profile-id="IncrediBuild Agent" />
</wpkg>
=========================================
Now, if i restart the WPKG Service, the Incredibuild program is installed,
but the log says:
=========================================
2011-12-19 14:30:04, DEBUG : Profiles applying to the current
host:|IncrediBuild Agent|
=========================================
Should not the WPKG_Client package from before apply too? If i continue
reading the log, i see that WPKG correctly checks if WPKG_Client is
installed:
=========================================

===========================================
But should not i have seen before something like:
===========================================
2011-12-19 14:30:04, DEBUG : Profiles applying to the current
host:|IncrediBuild Agent| |WPKG_client|
===========================================
instead of the only Incredibuild profile?
Intrigued by this, i added a third .xml in the hosts folder, called
Standard_Applications_hosts.xml, that contains the following lines:
===========================================
<?xml version="1.0" encoding="UTF-8"?>
<!-- Lists host names and associated profile. This file can be edited
directly, or even created automatically depending on your
environment.
For more info, see http://wpkg.org/index.php/Category:Documentation -->
<wpkg>
<!--host name="ultima" profile-id="Test" / -->
<!--host name="ultima" profile-id="WPKG_Client" / -->
<host group="Domain Computers" profile-id="Standard Applications" >
<profile id="7-Zip" />
</host >
</wpkg>
===========================================
But when i restart the service again, the new install profiles contained in
this new host are completely ignored by WPKG. The log continue to say that
the only profile that apply to this host is the IncrediBuild one.:
===========================================
2011-12-19 14:30:04, DEBUG : Profiles applying to the current
host:|IncrediBuild Agent|
===========================================
WPKG_Client existence is still checked, while 7-Zip check/installation are
totally ignored.
So, the question obviously is: why are the WPKG_Client, the Standard
Applications profile and the 7-Zip profile not seen by WPKG when it runs?
