There are some automated tools to check for this (see http://www.netmechanic.com/).

Making your own tool is not so difficult. You have to loop to all the pages, parse the HTML code looking for A HREF tags, take the URL and using a IE instance, call the Navigate2() method and wait for the return value (succesful or not).

The way I did to be sure links where always valid in a web site I mantained for quite some time was programtically generating all static or dynamic pages. If due to some program error a bad link was generated, it was simply a matter of fixing it and generating the pages again.

Hope this helps,
