Cause

There are several possible causes for this error message.

  • TIP: See separate IBM Technote #1669496 for more examples.

This Technote specifically relates to the scenario where the cause is that the Controller application server does not contain the required IIS virtual directories (in order to process requests from the client).
  • Specifically, it is caused by 'ibmcognos\controllerserver' being missing (or invalid).

Resolving the problem

Ensure that the Controller application server contains the correct IIS virtual directories/applications in its website, such as:

  • ibmcognos
  • ibmcognos\cgi-bin
  • ibmcognos\controller
  • ibmcognos\controllerbin
  • ibmcognos\controllerhelp
  • ibmcognos\controllerserver

TIP: The ones highlighted in bold are the most relevant directories for this issue.
