Hi.
You may or may not know that there is a particularity in IE about showing error pages.
IE has some option called "show friendly error messages", in the advanced settings somewhere, which has the effect of not displaying many HTTP server's sent error pages, but instead displaying a built-in IE error page. The pain with that, is that this internal error page is so specific as to completely hide whatever the server is sending as an error. In addition, IE shows this page for just about any kind of error at all, even when it has nothing to do with the webserver.
So the user's report ends up being pretty useless, because you never know where the error came from.
To a certain extent, you can override this at the server side, by making sure the error pages sent by the webserver have at least a certain size, which (sic) varies according to the error type, but as I recall 1025 bytes should about cover them all.
I believe if you google for "IE friendly error", you may get some additional info.

Thanks for the comments. I'm in the early stages of trying to track down this problem and its not something I can replicate.
All I know is that when I send out a mass mailing to 20,000 customers, I get on average 2 to 4 people saying the site is down and when I talk to them it turns out they are all using I.E. browsers, and when they switch to Firefox it works. My hosting company Hosting.com swears its not a server or DNS problem. My DNS server is managed by Hosting.com and its not on my Apache server, which is a dedicated server.
I seem to recall there were web server configuration settings that could remedy access problems or I.E. specific connection problems, but its been so long I cant recall where I came across it.
Just hoping if this was a common or known problem I'd get some tips on where to look if its a server issue.

A "Page not Found" error is a DNS resolution issue. Since apache does not provide DNS resolution, make sure that DNS servers in place on that machine are reliable, and if possible, disable DNS caching.
Good catch... forgot that. IE of course has some of the worst 'error reporting' I've seen. :)
