Hello everyone!
Please am developing a web application using vb.net with visual studio 2010 and .NET framework 4.0. its complete but i want it accessible over the network (LAN) so i have tried to host it on the local server (IIS) but i keep getting the following error message from IIS:

HTTP Error 500.21 - Internal Server Error
Handler "PageHandlerFactory-Integrated" has a bad module "ManagedPipelineHandler" in its module list

Please i need urgent help


That error could be caused in the configuration of IIS.

What you can try is;
Change Classic mode by integrated mode in IIS options, and it should work then.

I dont understand whta you mean by IIS options. Are you talking of the application pool?
