Users are not able to edit the web page on web server while traffic passes through the Load Balancer

Hi,

While we access the URL from Load Balancer, the users are not able to edit the web page. bypassing the loadbalancer works well.

When the user connects to the virtiual server they are authenticated through their AD ID. When they click on the button to edit the web site, IE shows Access denied error. with error code 0 in the bottom of IE.When we directly connect to the Node, theya re allowed to edit the page and access denied error is not shown. I thing there is some local authentication also happening the web server level that is preventing the user from authentication. Is there something which is blocking the Load Balancer IP to communicate with that local authentication on web serveror something like persistance etc...
