//
//	Dialog to choose a machine name.
//
//	PURPOSE
//	What you have to do is to copy all the files from the
//	snapin\chooser\ directory into your project (you may add
//	\nt\private\admin\snapin\chooser\ to your include directory if
//	you prefer not copying the code).
//	If you decide to copy the code to your project, please send mail
//	to Dan Morin (T-DanM) and cc to Jon Newman (JonN) so we can
//	mail you when we have updates available.  The next update will
//	be the "Browse" button to select a machine name.
//
//
//  DYNALOADED LIBRARIES
//
//	HISTORY
//	13-May-1997		t-danm		Creation.
//	23-May-1997		t-danm		Checkin into public tree. Comments updates.
//	25-May-1997		t-danm		Added MMCPropPageCallback().
//      31-Oct-1997             mattt           Added dynaload, fixed user <CANCEL> logic
//       1-Oct-1998             mattt           Removed reliance on MFC, changed default look to enable certsvr picker
