How can I check environment variable in Window 2000 or Windows NT? I have a
problem connecting to Oracle database, and I was suggested to check
the enviroment variable : TNS_ADMIN. I search for TNS_ADMIN in the registry,
but it could not find it. Thank you.

Right-click "My Computer", select Properties from the Menu, go to the
Advanced tab, and click Environment Variables...

Good Luck!

Thanks a lot.
So, to check for the enviroment variable : TNS_ADMIN, I should check under
"User variable" or "system variable", there is a variable called "TNS_ADMIN"
, right? Thanks.

Or, instead of typing set (which I agree is good for anyone to know
anyway), you could just type:

echo %TNS_ADMIN%

If the var exist, the command prompt will echo it's value. If it
doesn't exist, it will just echo what your echo is set to (ON or OFF).
 
Thank you all for your replies.
