We have a network of 10 clients running Windows XP with meinberg ntp. Clients are syncing with two ntp servers over a 40Km wireless network using mikrotik devices. Some of clients are connecting to ntp servers over a hop to hop links. ntp servers are syncing with the Internet. The problem is ntp clients are become out of sync after two or three days. After I restart service everything is OK. I should do this procedure every two days. I want to know is this because of long way wireless link? My ntp conf files are simple:
server 192.168.1.2 iburst server 192.168.1.3 iburst
Windows time service and firewall is disabled. Is there any solution? Am I missing any configuration option?
