Just wanted to share a few things we use with Prism deploy to make things a bit easier at our helpdesk.

First is a small cmd file i've created some other scripts that uses this one.
Build an package with an cmd file containing the following putting it somewhere like C:\program files\script with a shortcut to users start menu. When you have a support call you can then tell the user to click the shortcut and the users machine will poll the channel.

:Copy text below save as pollchannel.cmd
:Function to poll channel
:
if  exist  ""C:\Program files\Prism Deploy\Client\ptclient.exe""  goto  PD_6
if  exist  ""C:\Program files\New Boundary\Client\ptclient.exe""  goto  PD_7
goto end
D_6
"C:\Program files\Prism Deploy\Client\ptclient.exe" /subscriber
D_7
"C:\Program files\New Boundary\Client\ptclient.exe"  /subscriber
:END
EXIT

1. Place psexec.exe in c:\Program Files\Prism Suite on administrator workstation.

2. Add the following line to the [SingleComputerApps] section of ExternalToolsconfig.ini on administrator workstation:

   Poll Now="c:\Program Files\Prism Suite\Psexec.exe" \\%computername% -i -n 5 "<local path to ptclient.exe on managed system>" /subscriber
   Example: Poll="c:\Program Files\Prism Suite\Psexec.exe" \\%computername% -i -n 5 "c:\Program Files\New Boundary\Client\ptclient.exe" /Subscriber
   Note: There are may other switches that can be used with psexec. Check the documentation on the link below.

3. Restart Prism Console on administrator workstation.

You can download psexec.exe (which is part of pstools) here: http://www.microsoft.com/technet/sysinternals/utilities/psexec.mspx

I would like to see this available from the client machine as well.  Right click the Prism icon in the systray and select Poll Now.  I have a batch file users can run, but the right click would be more professional looking.
