Controller 10.3


There are several possible causes for this error.

  • TIP: See separate IBM Technote #1680674 for more examples.

This Technote specifically relates to the scenario where the cause is that the IIS Application Pool's "Process Model" is set to use the wrong "identity".

Resolving The Problem

Modify the relevant IIS application pool so that the “Identity” is set to “LocalSystem”.


1. Inside IIS Manager, open the section 'Application Pools'

2. Locate the relevant application pool

  • TIP: This is the one that is running your ControllerServer virtual application

Controller 10.3 (or later):

By default, this is the one called ‘.NET v4.5’ (with a managed pipeline set to 'Integrated')

Controller 10.2.x:

By default, this is the one called ‘.NET v2.0’ (Integrated)'

3. Right-click on the relevant application pool (for example ‘.NET v4.5')) and choose 'Advanced Settings'

4. Modify the setting “Identity” to be “LocalSystem”:
