Hi! Thanks for all the replies... But may of the solutions are not for my question. Friends! E.g. : If user1 has logged in Internet Explorer on IP adress (Say IP - A) with MAC Adress (MAC-X) Then No other user can login on that IP (IP-A) AND MAC Adress (MAC-X) on any other browser say Firefox. I can stop any user to login more than one time at two different machines.. But I am unable to stop Multiple logins on same machine (ofcourse on different Browsers) Because each browser has different SESSION and Cookie system. I hope problem is very clear now.. regards Jagdeep Singh On Fri, May 14, 2010 at 9:51 PM, tedd <tedd.sperling@xxxxxxxxx> wrote: > At 12:48 PM +0530 5/14/10, Jagdeep Singh wrote: > >> Hi All! >> >> I am looking for a solution, I want a user to do a single Login only on a >> PC >> . >> >> E.g.
