That’s interesting. (I don’t see that behavior on my LAMP or IIS installations.)

Do you have the “Custom Structure” option with an empty text field? You could try http://localhost/wp-sqlsrv/%monthnum%/%postname%/ that way.

What happens to your site if you switch your permalinks to simply be http://localhost/wp-sqlsrv/%postname%/ or http://localhost/wp-sqlsrv/%month%/%postname%/?

I’ve also used WP on IIS with mixed success. However, I’ve never tried to use SQL Server to host the db. Your rewrite rules look right to me. How have you set your permalink settings up within WP (from the Admin area, it’s at Settings > Permalinks)?
