Wordpress 301 loop

We recently had an upgrade done to our site which runs both HTML and Wordpress, depending on where a visitor lands.  Our developer changed the web.config which (we think) has caused our Wordpress pages to redirect loop when links from Google are clicked on.  

Is there something in particular I should look for to correct this issue?

Had to omit the Wordpress directory from our URL rewrite.  Problem solved.
