Problem with Form authentication

Hi Guys,

I am using form authentication to secure my project. It is working fine in my machine. When I deploy the project in to the server, it works in only few machines, few machines it does not work. it keeps sending back to the login page again and again, as I am tracking the login, it been logged properly and stores in the database. But some reason it is not redirecting to the page they wanted. but same time my friend has done same thing in vb.net it worked fine. But I have done in c# it is not working. Has anyone faced that same problem? if so how did you solve that problem.

Thanks,
dummy.

On the machines on which it's failing, do these machines allow cookies?
