Hi,
I'm having a up and running web based system which authenticats users from the active directory. IIS hosted in a server pc and AD is in a normal PC which runs server OS. This works fine for past 4 years. Since few months I'm having issues of authentication. When user enters user name and password it prompts again and again. Restarting IIS server computer solves this issue at times, but not always. This has been a headache for me. Waiting for any comment which helps to solve this issue.
Thanks in advance.
