More Information:
This error occurs when there is a problem reading the configuration file for the Web server or Web application. In some cases, the event logs may contain more information about what caused this error.
Cause
There are many possible causes for a similar error.
This Technote specifically relates to the scenario where the cause is that the Controller application server's IIS settings are incorrect.
Example:
In one real-life example, the server was configured to use 'DefaultAppPool' but that application pool was configured to use .NET version 4.0: 
- TIP: For more examples, see separate IBM Technote #1986254.
This Technote specifically relates to the scenario where the cause is that the Controller application server's IIS settings are incorrect.
- Specifically, the Controller web application is configured to use the wrong .NET Framework version (4.0 or later).
- This is the wrong version for Controller 10.2.1 (and earlier), which requires .NET 2.0
Example:
In one real-life example, the server was configured to use 'DefaultAppPool' but that application pool was configured to use .NET version 4.0:
Environment
This Technote only relates to Controller version 10.2.1 (or earlier).
- NOTE: Controller 10.3.0 (and later) use .NET Framework 4.0 (or later).
Diagnosing The Problem
Read the on-screen error message carefully. Look for the following sections:
- Error Code
- Config Error
Resolving The Problem
Reconfigure the IIS Application Pool configuration on the Controller application server, so that the virtual application 'controllerserver' uses .NET 2.0.
Steps:
Steps:
The following steps are based on Windows 2012. They may need to be adjusted slightly for other versions of Windows.
1. Logon to the Controller application server as a Windows administrator
2. Launch Internet Information Services (IIS) Manager
3. Locate the virtual application 'controllerserver'
4. Right-click on controllerserver and choose 'Advanced Settings'
5. Make a note of the current setting for 'Application Pool' (for example 'DefaultAppPool'):
Assuming that the current setting is 'DefaultAppPool' then the author's preferred solution is to move this application to the standard .NET 2.0 application pool.
2. Launch Internet Information Services (IIS) Manager
3. Locate the virtual application 'controllerserver'
4. Right-click on controllerserver and choose 'Advanced Settings'
5. Make a note of the current setting for 'Application Pool' (for example 'DefaultAppPool'):
Assuming that the current setting is 'DefaultAppPool' then the author's preferred solution is to move this application to the standard .NET 2.0 application pool.
- Alternatively the customer may choose to use the 'alternative method' (see end of this Technote).
6. Open the section 'Application Pools'
7. Right-click on the relevant entry (for example 'DefaultAppPool') and choose "View Applications":
8. Right-click on the 'controllerserver' entry and choose 'Change Application Pool':
9. Choose ".NET 2.0" and click OK:
10. Test.
===============================================
Alternative method:
If desired, you can (instead) modify the default application pool to be .NET 2.0.
- To do this, replace the above instructions (from step 6 onwards) with the following:
6. Open the section 'Application Pools' and locate the relevant application pool (for example 'DefaultAppPool')
7. Double-click on this application pool
8. Modify the setting ".NET CLR Version" to ".NET CLR Version v2.0.50727"
