Dear friends, We have Pix520 firewall and cisco secure2.5 on Windows NT 4.0 and using windows NT users database, the problem when cisco secure authenticate user who are using internet browsing it prompts user ID and Password several times and then says page can not be displayed once you refresh the page it goes for browsing without getting authenticated, sometimes it authenticates properly, I wonder if someone knows this unsuitable behavior.
