Hi <BR> I have implemented Digital Certificate validation in my program.But when i run my asp page it is not prompting the certificates that i&#039;ve imported in my machine.The same code is prompting to choose DC,when its run in my colleague&#039;s machine.I guess there is a problem with the IE,but i checked with the security level and others.Everything is perfect.Where else could the problem lie. Anyhelp would be greatly appreciated.<BR><BR>thanks in advance<BR>kgdsamy
