I am about to update the time on my Primary Domain controller. I have server 2003 R2. The time on my network is currently 5 minutes off from the actual time. I have received the information on how to do the update but I have heard that if the domain controller is more then a couple of minutes different from the computers there can be a communication issue. Is this true? When I update the time on the domain controller will it populate to all other computers on the network automatically? And finally how long will it take for the other computers to receive the update?
