I have Used Resgistration and loggin control in my asp.net 2.0 application. If i logged in my application, in the same time i could able to loggin to my application from different machine(local) using the same username. How to prevent the user should not login using the same username at the same time.

Thanks

Dear there are multiple ways to block this process.

1) U can use char(1) in database which will be set when person logon first time. When u authentication to database for correct Id and Paw, select only records which don't have char(1)(eg.Status) field set.
