I am using ASP.Net with membership. I have everything set up and running well. I think. One of the users has been unable to login. He has the correct username and password, but it will not work for him. He's tried different browsers, too (ie and mozilla). As the admin, I can login as myself or any other user (still in the testing phase pretty much, passwords have not been reset). So trying it from 2 different computers everything works for me, either logged in as myself or any other user. Any ideas what could be going wrong? I was wondering if the log out button is not working properly and perhaps the cache is messed up. I'm at a loss. Any ideas would be appreciated. I;m using ASP.Net and C# (VS 2008), plus SQL Server 2005. Thanks.
