Hey guys, can you suggest how I can do the following, or where I may find information on how to.

I have a user login page and want to know if you can make sure that there is only one user loged in at the one time.

E.g.
If a user is logged in and then another person tries to login with the same username, they are both locked out or something like that.

I have created the site using DWMX04, ASP & ACCESS.

Thanks Heaps.

Mally.
