See more:

we have windows authentication based application where we have to identify user with his domain and if he is valid he directly should get logged in to the application but if authentication fails then he should get redirected to login page.

where he has to enter id and password to access the application but when authentication fails at that time it is giving windows prompt to enter windows id and password rather then redirecting to login page

You need to use the Location tag in web.config to allow all users access to LoginPage.aspx. An example is in the MSDN documentation:

http://msdn.microsoft.com/en-us/library/b6x6shw7(v=vs.85).aspx[^]

This way, when someone tries to get to LoginPage.aspx (or whatever yours is called) .Net will not try to authenticate them but will allow everyone access to just that one page.
