Change managed pipeline mode in IIS 7
If you are running into odd errors on your site or cannot get a piece of code to work properly it may be the managed pipeline mode is incorrect. You can change this under the basic settings of the application pool. Often setting this to classic will resolve issues. Follow the instructions below to change the managed pipeline mode in IIS 7.
In IIS 7.0, there are two request-processing modes for application pools: integrated mode and classic mode. When you configure an application pool with integrated mode, IIS processes requests for managed content with the new integrated IIS and ASP.NET request processing pipeline. When you configure an application pool with classic mode, IIS continues to process requests for managed content using the separate IIS and ASP.NET request-processing pipelines. Use classic mode only for applications that cannot run in integrated mode.
1. Login with remote desktop and open Internet Information Services on the windows 2008 server. This is found under Start Menu, Control Panel, Administrative Tools, and then Internet Information Services (IIS) Manager.
2. Click on the + next to your server name and then click on Application Pools.
3. Locate the application pool for the website you are changing asp.net for. Right click on the application pool and click on Basic Settings.
4. From the drop down menu under Managed pipeline mode: choose classic then click on ok. (Integrated is the default mode.)
