NT is not ready to support the thousands of users and millions of transactions in real time, at least not in such a way as to make IT feel particularly comfortable with it. In order to get the most for their infrastructure dollar, IT people are keeping existing and mission-critical applications on UNIX servers, then connecting them to smaller NT servers.

Instead of porting UNIX to NT, UNIX applications should be kept on UNIX and NT apps on NT.
