>"SQL Server and Windows NT" really means "You can use either SQL Server security or Windows NT security" or "both will work". So that is why you don't need to log into the NT domain if you use a username/password to log on to SQL Server.

Then - how can I explain this - over the internet I can try to do SQLSTRINGCONNECT from VFP to a SQL Server set up for SQL authentication. I can NOT get in - yet if I first "log into the domain" by mapping a drive in explorer - I can then get into the SQL Server?
