Dimitry, if your PC will not allow cookies, you can forget about developing Forms Authentication on it. Everything is dependant on the authentication ticket that is stored in a cookie on the client.

>Even if I put a specific code to create a cookie, it won't work. However, if I run my ASP.NET page right from the VS.NET (by right mouse clicking on the page and selecting to run it in a browser) the cookie will be created. As I mentioned I tried with IE and with Firefox and neither works. So I guess it is something different.
