As you know, I've had my issues with app pools lately, and I'm pleased to report the many issues involved have one by one been rectified.

Without having access to the back end to review settings and not knowing the URL of the website, it is very difficult to reply, we would be guessing at this point. The only advice I would give is to ensure that the default document setting under the website is properly defined.

There's a good chance you may have to tweak the app pool settings here, but that depends on many other factors. As you know, I host my site with your company, and someone changed my app pool to include 32 bits; after it was changed back to 64 bits, it seemed to help rectify my many issues.

I am implementing best practices on the app pools setting to take it even one step further. I am also increasing the ram, regardless of what the resources say. It is my intention to split the app pool into multiple threads based on the number of CPU cores. This should help spread resources more evenly across the server.

There are many factors involved in play, but you could take a screenshot of the App Pools setting and post it to see if anything is out of the ordinary.

I know this is difficult, and I hope some of this helps.

Judy,

We never see the issue like this. It is hard to say anything without looking at the IIS configuration. Is the site customized? You can check the serve logs for more details about the error from the server's event viewer.

There might be some broken widget on the home page causing this. Can you try Reset All changes from home page (keeping the backup) from /Admin/Website/CustomizedPages and then apply the widgets again?
