I have recently setup a medium size network with around 70 switches and I am now getting to the point where I need to configure the time on those switches. I understand that I need to identify a device to use as NTP server. We don't currently have a spare router so the option is to buy one to use solely as NTP server. Does any of you know the cheapest cisco model i could get as it would be a waste to get an expensive one just to use as NTP server unless there is another way that does not involve getting a Router. Also can I use a windows server as an NTP server to use with switches?
