An Error Occurred While Trying to Access the Server

While trying to start or log on to IBM® Cognos® Controller, a message states that an error occurred while trying to access the server.

This error can occur for several reasons:

  • The Controller Web Services Server may not be running.
  • The COM+ Server may not be running.
  • The Controller database connection logon credentials may need to be reset.
  • There may be errors with the configuration of authenticated access.

Tip: If the error occurs after you start IBM Cognos Controller, then in Administrative Tools use the Event Viewer on both the IBM Cognos Controller client computer and the Controller Web Services Server computer for internal errors.
