Re: Forms Authentication - Sudden Redirect Failure on Login

Any resolution to this issue? I have a similar problem: developing a
web app in VS 2005 using forms authentication. My dev box is win XP and
the app is in c#. Forms authentication used to work just fine on my dev
box. Recently, the login page is not redirecting to the return URL, and
I keep getting the login page back. I have a directory in the app with
all the pages that require login. The directory as well as the login
page are defined in web.config. Last version of the app is deployed to
a win2003 server is working fine there. Now, I can't deploy the latest
version until I fix forms authentication on my dev box and figure out
what's going on?

The code is very similar to Stephen's and the debug statements yield
similar values. Sounds like an environment issue but I can't figure out
what has happened. What do you guys think. Thanks, Khaled.

To confirm if this is .NET framework issue, you may first try to
re-register the ASP.NET on the server:

Aspnet_regiis -ua

and then:

Aspnet_regiis -i

And you also can try to repair the framework:
