We have ELMAH enabled on our site and get errors whenever a Page Not Found error is triggered on the website.

For this reason, we have set up permanent redirects for such previously indexed pages to the respective new pages.
The website in mention is
www.chambercollege.com and for example, a previously indexed URL was
www.chambercollege.com/special-offers.aspx. This page is no longer accessible so we have created the necessary permanent redirect to redirect to the respective page on
Now we are starting to receive Page Not Found errors of search engine bots (e.g. MSN bot) trying to access the URL
Any idea how could a search engine make up that strange URL and whether you have any suggestions of what to do best?
