I'm new to SQL Server and didn't do the install. I've lived happily with MSDE for two years until we hit the limit.
When I connect in HQ Admin I can connect to my database using Windows Authentication and the database connects. I can query it too. When I try to use HQ Manager (on the same machine running SBS2003) I get an error message "sa not associated with a trusted SQL Server connection". I changed the SQL setup to accept mixed authentication. I reset the sa password. I don't know what else to do.
