Do you need a license for old, no longer supported (SQL 7.0) software?

Hi there,

I am wondering if you really need a license for old software?

Particularly SQL Server 7.0, my friend is (for some inexplicable reason) using it for his Windows NT 4.0 based data center. I kid you not!

The fact that is doesn't support IPV6 and many other current technologies makes it likely he will never actually launch and see a paying customer.

But that is hardly relevant, since he searches out SQL 7.0 Unlimited CAL licenses and pays ridiculous prices for them (He's the only buyer in the whole world I think...)

Can anyone confirm that he even needs a license at all?

Thanks,

Josh
