Been having this problem on a site collection where 'NT AUTHORITY\authenticated users' is made a member of the site visitors group so that everyone can read the content - not sure when this actually started but it was not always like this! On first access users are denied access but on clicking 'go back to site' the user gets access to the site and can read all the content. The access denied page url contains no guid to track down - just the url of the site itself! What could cause this to happen?

Hi, Go to your event viewer and ULS logs (...\Microsoft Shared\web server extensions\12\LOGS folder with the name format of ServerName-Date-Timestamp.log as default configuration) to check if there are errors regarding SharePoint and let me know the detail information. Hope it is helpful! Seven
