Hi,
I have Hosted a VB.Net application in IIS using Form Authentication and intermettinently we are facing (LDAP ) AD Authentication issue suddenly .While logging through web application got "Incorrect USername and Password" .If i restart the IIS, Issue was resolved.
If i change the IIS Idle Timeout and Session State settings will Solve this problem? Now IIS Idle Timeout set to 20 mins and Session State set to 30 mins.
We have checked AD logs and Server logs we couldnt find any cause. Please give some idea how to analyze this issue.
