DB2 UDB connection failed

[Steve Richter <stephenrichter@xxxxxxxxx>]

I have downloaded DB2 universal database to my windows 2000 PC.  The
plan being to use it to connect my .NET applications to the as400
database.

http://www-306.ibm.com/software/data/db2/udb/

I am getting an error when I test the connection to the as400: 

CLI connection failed.
SQL8002N  Connect processing failed; a valid product license was not
found.  SQLSTATE=42968

I have a valid license for v5r1, 5722ss1, 5050 on my system.  But
apparantly, I need a license for something else.

I called the Boulder license key center and the friendly people there
said they can give me a temporary key, but they dont know which
product I need to be licensed to.

That is the question.  What as400 product and feature is needed for
DB2 to be able to connect from the PC to the AS400?

thanks,

-Steve
