Synching time on multiple workstations

My boss recently asked me to research the ability to standardize the time on all of our win2000 workstations (300+)from our win2000 server. He told me to lookup timesrv.exe and w32time.exe to implement as well as other possibilities. Technet wasnt so forthcoming, I found some info about and how, but nothing substantial. What does everybody else use to control uniform time on all pcs? Any input would greatly be appreciated. Thx
