We are STILL using NT Server 4.0 at are server, and we recently upgraded to Access 2000 for our database. The databases themselves exist on each workstation and the raw data is being stored on the server. In other words only the raw data is traveling through our network. I'm interested in upgrading the database engine on our server to the latest 4.0 service pack. (currently we are running version 3.51.2026.0) Should I upgrade the database engine version on the NT server and if so, are there any known problems or issues I could run into?
