Often times IE will say there is a DNS error when really, it's some
other error such as the server failed to respond appropriately.

For example, I was writting a query for PostgreSQL and PHP.  I was using
a join that had an implicit table reference.  However PostgreSQL would
issue a warning and this warning caused APACHE to segfault after a
little while.

Looking in my /var/logs/httpd/errors I noticed a lot of dead apache
children.  It was these dying apache process that were causing the exact
error that you are talking about.

Because the apache process died before a header was being sent to the
browser, IE was getting no response and therefore issued a DNS error. 
In Netscape, I simply got the error, "The Document Contained No Data."

So if you are getting DNS errors sporadically, check your Apache error
log.  I think you'll need to be root to do that.
