Restart your machine...Hope it will work. Thanks, Chintan(India)

Just for further info: The problem is that I run my web application in debug on my XP Pro machine and I can logon to the web app using the settings I defined using the WSAT (web site administration tool). If I deploy the web application to another XP machine, I can't seem to login using the username I defined. I can't understand what's going on! Does there need to be some reference to the ASPNETDB.MDF file in web.config?
