I am currently researching this same error message. My parameters are a bit different. I have found a detailed description on another site [url]http://www.webmasterworld.com/forum46/225.htm[/url] that speaks of the issue being a cacheing issue on NT machines running IIS4.

Surf to the above link for more details.

I cannot confirm or endorse the fix - so proceed with caution.
