If you plan on installing Small Business Accounting 2006 on Windows Server 2003, be aware that the multi-user setting menu will throw an error unless you enable Internet Connection Sharing (ICS). ICS can be found be right-clicking on the active network adapter and going into properties. You’ll find the setting under the Advanced tab. Enable ICS and add a new service for TCP Port 56183. This will allow SBA 2006 to communicate and open itself up to external boxes.
