Page Cannot be displayed

Hi

I am using IIS 6 on Windows server for hosting my web application written in Perl using CGI.

My page returns a response 90% of the time. On random instances, it fails and gives 'page cannot be displayed' error. I have tried using fiddler to capture the http response code, but always get 200 even when the page fails to display. I am getting this issue in IE consistently.

Any pointers appreciated.
