Have a DOS program installed on a new NT 4.0 network. All 5 machines on the network are 233MHz. All have 3COM 10/100 cards, all cat 5 wiring and 100MHb hub. Perf. Mon says only using 2% of available resources and nothing else is running on the network, except for MSMail which is very infrequent. Software runs great in Novell. Looking for suggestions increase response time.
