I get "Byte-Order Mark found in UTF-8 File" followed by
"This Page Is Valid HTML 4.01 Strict!"

You have probably changed something. Or maybe you meant some other page.
If I try e.g.
http://www.cmsbuffet.com/cms-about-us.phpfoobar
I get roughly the same browser, but that's an illusion. What the server 
sends is the 404 error code and some data, which _shall_ be interpreted as 
an explanation of the error condition, _not_ as resource content 
corresponding to the URL. A validator (as well as a search engine) acts in 
a protocol-correct manner, treating the error code as primary information.

So your error handling is in error and should be fixed. The error document 
should explain the error condition and give the user suggestions on 
finding what he might be looking for, like a link the main page, site 
map, or search page.

To validate the error message page, simply submit its own URL to the 
validator. The error message is normally accessible by a URL of its own, 
as a normal page.
