No previous install had been done on this server.

I have tested the MS install on a Win NT4 PC and it worked fine. (version 7.2 eval) I need to try MS out on the Win2000 server but all I get is the first screen telling me this is an evaluation version and I can Continue, Order, help or Cancel. Clicking on Continue does nothing except bring the same...

I am running NT4, installed MS under Administrator, log in as Accounts.
How can I make sure MS runs when I log in?
I have a script that needs to run each 30 minutes.
