I am working on the blog for a client who uses Word Press on IIS. When you go straight to the blog you can view the most recent articles, and you can access articles in the archives individually if you know the article URL. The problem is that when you try to browse the archives by month or even click the "Older Entries" link on the bottom of the page it generates the error "The specified CGI application misbehaved by not returning a complete set of HTTP headers." The fact that you can get to individual articles with the friendly URLS makes me think it isn't a mod_rewrite issue, but I am not sure. The site can be seen at: http://www.castercomm.com/blog/ if you want to poke around. Any suggestions would be appreciated.
