I'm glad I asked < g >
For benefit of anyone as ignorant as I am :
I was using Windows NT Verification - recommended but crunchy with the examples one mostly finds re connection strings.
Went to enterprise manager, right-clicked on icon for local server. On security tab changed Authentication from Windows Only to SQL Server and Windows
On the treeview in the left panel, again right clicking on local I was then able to change the Registration properties - this time changing from Use Windows Authentication to USE Sql Server Authentication.
Now all is well with Kevin's book sample and other things and examples re connection strings etc seem to be behaving as advertised.
Perhaps I'm the last person on earth to learn all this, but then again perhaps it will save some other hapless soul from my confusion.
( Great book Kevin - enjoying it very much. I being a VFE er ( a close cousin to the MM ers ) I am very fond of business objects and decoupling logic from presentation. You examples in this direction are very good and I am sure MM .NET is going to get a lot of folks involved in best practices on this stuff)

Though a good deal is too strange to be believed, nothing is too strange to have happened.
- Thomas Hardy
Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.
-- T. S. Eliot
Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.

Pardon him, Theodotus. He is a barbarian, and thinks that the customs of his tribe and island are the laws of nature.
