Business Notification on Windows 2003

Does anyone have Business Notification running on Window Server 2003? My configuration is as follows: Windows 2003 Server with SP1 .NET Framework 2.0 SQL 2000 SP4 SQLXML 3.0 SP3 Notifcation Services SP1 Navision 4.0 SQL This is all on one server, as this is just a testing environment. When I attempt to select a template (new from template) I get the following error: “There are no business entities available. Please insure that there is a company selected in Navision” Based on other post on this board I have checked the following: 1. I have selected a company. 2. I have a good license (NSC). 3. All user accounts being used are Domain Admins and SUPER in Navision. I realize that some of this software is newer version than listed in the Business Notification Install Guide. Will this configuration work, or do I need to downgrade my operating system? Any suggestions/comment appreciated.
