"ASP.net settings not applicable in integrated managed piping mode detected" IIS7 in Windows 2008 resolves

HTTP Error 500.23-internal Server error

Detects asp.net settings that are not applicable in integrated managed piping mode.

The solution is:

Open the application pool in the corresponding IIS for this web site, and the managed pipe selects "Classic".

But after you modify, the RP is good, may really run up, but the RP poor then another problem

And ultimately the solution is in Web.config. Step one: First find the node in Web.config <system.webServer> if not, create a node under the <configuration> node. Part II: Under <system.webServer> node insert the following configuration <validation validateintegratedmodeconfiguration= "false"/>
Save or create a new web.config, pay attention to pipe mode or select integration mode, the problem is solved perfectly!
