 Most likely causes:
•system.web/identity@impersonate is set to true.
 Things you can try:
•If the application supports it, disable client impersonation.
•If you are certain that it is OK to ignore this error, it can be disabled by _
  setting system.webServer/validation@validateIntegratedModeConfiguration to _
  false.
•Move this application to an application pool using Classic .NET mode - for _
example, %SystemRoot%\system32\inetsrv\appcmd set app "Default Web Site/" _
/applicationPool:"Classic .NET AppPool"
(You can set "Classic .NET AppPool" to the name of another application pool _
running in Classic managed pipeline mode)
