I need some basic education.  Occasionally, users trying to make initial 
access one of the websites I host get a "page not found" type error.  Other 
users at the same time are connecting with no problem.  The page to be 
returned is a simple HTML page, and WAA is not involved in this issue.  The 
different websites have different authoritative domain name servers.  It can 
be any of three websites that people have problems with.  What is going on? 
Can I do anything about it?

Bruce,
if I understood what you wrote correctly you cannot do anything about it. It 
is caused by the DNS in use.

This sounds like som kind of DNS resolution problem. Talk to the provider
that hosts the domains / DNS servers.

1.  What web-server software are you using?

2.  Do you know the exact error being returned (404 is rather ambiguous).

You can check whether the 404 is generated by a DNS error or by the web
server.  Simply check the web-server error logs, they should record
requests that cannot be resolved.  If there are no log messages for these
errors, then it will be a DNS issue.
