Keith,
I agree with you. But the problem is that my PC (or I should say MSFT IE) allows cookies to be created by any site I visit. It is only my own ASP.NET application that is denied by IE to create a cookie. Very strange problem. I am thinking about reinstalling IE all together, although, I am not sure if there could not be some other side effects by that.

>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.

>>I did but to no avail. You see, as I indicated in the inital message, there is something strange on my PC or on my .NET setting that it won't allow me to create a cookie from ASP.NET page.
>>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.
