Welll My install was a no go. AC installed on the server as a native client of sql 2005 under SBS converted databases running fine BUT when I installed on client computers sql client install failed. It installed the components O.K but got a fail message after AC configured. Running win 2K and win pro on clients and it failed on both. It acts like a port problem to me. Looking at the tutorial I never saw any screen showing me to to configure firewall sql port etc. when I installed on the server Any ideas? By the way thanks Bert for the link.
