I really don't know what I did to do it...maybe it was the 2 hours of praying since I last took out time to touch the PC...but at any rate PHP is now referring to the php.ini file located in c:\winnt.
I did do the following. Whether this is the cure, I have no idea.
I removed the php.ini file from winnt and placed it in another directory, in my case. \temp.
I restarted Apache. phpinfo() still showed php.ini being in the winnt directory even though it wasn't.
I copied php.ini back to c:\winnt from c:\temp and restarted Apache.
Worked like a charm.
End of story.
