Why your network needs to keep perfect time.

All networks have issues. Issues require troubleshooting. One of the worst scenarios I ever had the joy of walking into was a network full of devices that were not time-synchronized.

There are two major issues that manifest themselves on badly synchronized networks.

Logging

When scouring logs from several devices to track down why something isn’t working right, it helps if all of these log events are synchronized from device to device so that you can cross-reference events from one end of the network to the other.

Authentication

On some networks with a Windows Domain Controller, time synchronization can be extremely important in the negotiation of workstation logins. When time is off by so much on the workstation, the server simply wants nothing to do with it.


The solution to these issues is quite simple. Set up an internal time server that will provide your entire network with a heartbeat you can depend on.  Don’t forget, all other devices on your network will need to point to your NTP server to sync their time.
