Get a copy of REGSHOT and then on a clean system run the first snapshot of the system, then create your DSN, then take the second snapshot of the system.

Then do a compare and:

You should see these keys modified (and maybe a few more depending on options selected)

HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\ConnectTo
HKLM\SOFTWARE\Microsoft\MSSQLServer\Client\DB-Lib
HKLM\SOFTWARE\ODBC\ODBC.INI\ODBC Data Sources
HKLM\SOFTWARE\ODBC\ODBC.INI



You can then easily write some Admin code to remotely add this entry to any system you have Admin rights on.
