Actually, if you read MS's docs you'll find that NT4 SP3 _does_ support the Direct3D 
API, _but_ there is no support for _hardware_ acceleration:

There are rumors that NT4 SP4 does / will have support for a higher version of 
DirectX, but again you'll have to check carefully to see if they consider "support" to 
mean merely the API or full acceleration.
