Hi all, good evening, We developed an asp.net 3.5 application. Its deployed and working good. Now I need to deploy this same application in a server which is having only .net framework 2.0(Windows-2003 R2/64Bit). When I am trying to deploy, I choosed Asp.Net version is "2.0.50727". When I am trying to login to this application, it does not go forward from the login page even though I gave valid credentials. If I click on the login button it will always resides on this login page only (no redirect to application).

If I change the Web.Config file which is compatible to 2.0 framework in the application, my application show huge errors. Because I used Script Manager tags, Update Panels, AJAX controls etc.


Please suggest to solve my issue.

Thanks in advance.
