Comment(by Frumph):

 I traced it to being a problem here: in wp-admin/includes/misc.php

 {{{
 function iis7_save_url_rewrite_rules(){
         global $wp_rewrite;

         $home_path = get_home_path();
         $web_config_file = $home_path . 'web.config';

         // Using win_is_writable() instead of is_writable() because of a
 bug in Windows PHP
         if ( ( ! file_exists($web_config_file) &&
 win_is_writable($home_path) && $wp_rewrite->using_mod_rewrite_permalinks()
 ) || win_is_writable($web_config_file) ) {
                 if ( iis7_supports_permalinks() ) {
                         $rule = $wp_rewrite->iis7_url_rewrite_rules(false,
 '', '');
                         var_dump($rule);
 //                      if ( ! empty($rule) ) {
 //                              return
 iis7_add_rewrite_rule($web_config_file, $rule);
 //                      } else {
 //                              return
 iis7_delete_rewrite_rule($web_config_file);
 //                      }
                 }
         }
         return false;
 }
 }}}

 If I comment the if (!empty$rule)) section it seems to work fine for
 creating and not keep retrying to input the rules over and over

 the var_dump($rule) I put in there is returning this:
 {{{
 string(2248) "                                          "
 }}}

 Which seems a little odd.
