We have retail sites which run Windows XP on their POS (point-of-sale) machines. These machines are in a workgroup and therefore do not have the luxury of using domain controllers to keep machine clocks in sync.
I've been asked to investigate the possibility of using the in-store Cisco routers as the time-source. The router models used are 877G and 877VAMG.
Are these routers capable of doing this and what would be the process on both the router and the Windows XP machine?
