Web service hosting in IIS : Error HTTP Error 500.19

I created a simple web service in VS 2010 (target framework 3.5) and published in IIS 7.5 But when I tried to browse it got following error.

**HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed
because the related configuration data for the page is invalid.
Error Code 0x80070021

Config Source:
97:
98:
99: **

How to resolve this error?

It is working when Target framework is changed to 2.0/3.0 but not working for 3.5

One more thing I had installed VS 2010 before installing IIS. So is there will be any issues because of this?

Theerror messagelikely to occur due to your ApplicationPoolIdentity not being assigned the permissions. Your web application belongs to an application pool and so you need to give the permissions to the OS account that your web application's application pool runs under.This can be NetworkService or you may have customized it to run underyour account .Please set the Identity this would work

Kindly Check the server configuration if the server is 32 bit you might had developed your webservice in 64 built go back to your solution and change the build change it to 32 bit and install that service on server . If your server is 64 bit then try to build that project in X64 .
