Some games, for example, achieve dramatic effects by directly accessing the hardware. Purchasing enough memory is the most important consideration in setting up an NT server that makes users happy. Do not try to run NT Server with less than 128 Meg. Do not try to run Workstation with less than 32 Meg. It is strongly suggested that an NT server should have two CPU's.
Reliability is a critical characteristic of a server.
It does provide a level of reliability, but critical operations such as school records may require that you should purchase a true RAID system, although it is expensive. The NT implementation is free. A true RAID implementation will require additional hardware and software. Overall, as stated earlier, Windows NT is a fine operating system. The positives tend to focus around reliability and similarity to the Windows operating system.
