Recently reinstalled the Windows7, after installing the VS2010 development Platform, published the Web site to IIS, the following error occurred in the access:
HTTP Error 500.21-internal Server error handler "Nickleecallbackhandler" has an error module in its module list "Managedpipelinehandler"
Cause: After you install the framework v4.0, IIS is enabled, causing the framework to not be fully installed
FIX: Start with all programs, accessories, right-click Command prompt, run as Administrator->%windir%\microsoft.net\framework\v4.0.30319\aspnet_ Regiis.exe-i
If not, check the application pool for IIS, use Integrated mode, or change to Integrated mode if not
My solution is as follows:
Run->%windir%\microsoft.net\framework\v4.0.30319\aspnet_regiis.exe-i as an administrator in cmd, and if the installation succeeds, you will see the following
If that doesn't work, just examine the IIS run Pool mode is not an integrated mode, and the. Net Framework version is not 4.0, as follows:
HTTP Error 500.21-internal Server error solution (GO)
