Not normally due to the higher security features of Server2003.
But you can reduce the level of security to make it work, but I don't like
doing that. The same problem will occur with Win95 Clients and NT4 Pre SP3
Clients.
We have some equipment that runs on DOS here (Teleprompter and an MCU). But
we have a separate NT4 Domain for them to attach to and use. Next year those
will be gone,...the whole system is being replaced.
