You CAN actually set the TNS_ADMIN variable in the registry under
HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE/ - It may not be there at first, all you
need to do is create a new "key" called TNS_ADMIN with a value of the path
to your master tnsnames.ora file.

versions of tnsnames.ora in NT/W2K]


In Unix, one can create links to a master by "$ ls -s <some master
tnsnames.ora> <some other location/file>".
(I know, I could, and probably should, use the TNS_ADMIN environmental
variable instead.)

There seems to be no equivalent of this in NT though.  Creating a "shortcut"
doesn't seem to work.  Copying files around seems primitive at best.  Am I
missing something?  [OK, OK!  I'll reform and use the environmental
variable!]
