When right-clicking on a computer resource and choosing "Manage Users", the following error occurs:


     "Unhandled PPA exception. See InnerException for details."

When referring to the Altiris logs, no related errors appear to have occurred.


  • Real-Time System Manager 7.0.1299
  • Real-Time Console Infrastructure SP1 7.0.1299
  • Pluggable Protocol Architecture SP2 7.0.6455


1. This condition will occur if you have the Symantec Management Platform Installed to a path which is not the default (e.g. E:\Altiris). This is caused when a repair has been run on "Altiris Pluggable Protocol Architecture" within the Symantec Installation Manager. The repair causes certain registry values to be set to the default path of installation instead of the proper alternate path. This behavior is a defect and has been submitted to development.

2. This error can also be returned if the target computer has the Windows Firewall turned on because the firewall is probably blocking the port through which WMI is attempting to communicate through.


1a. Modify the following registry values to point to the proper installation path of the Pluggable Protocols:
    Example:  If Altiris has been installed to: "E:\Altiris", then these values should be:
     BinariesPath:  E:\Altiris\Pluggable Protocols Agent\bin
     ConfigPath:  E:\Altiris\Pluggable Protocols Agent\bin\Config

1b. Either reboot the Notification Server, or run "iisreset" and restart all the Altiris Server services

      This issue has been addressed by development and will be resolved in Pluggable Protocol Architecture SP4.

2. If the problem is related to the Windows Firewall being enabled the problem is compounded by the fact that WMI (in operating systems other than Vista) do not have the ability of statically assigning a static port through which WMI can communicate. See KB 41179 for an explanation and possible workarounds.
