One of the most common mistakes I see when out in the field with VMWare, is incorrectly configured VMWare ESX servers. It is very common to see people configure virtual machines as if they are physical machines. If you are going to implement VMWare in your environment I highly suggest going...

IT consultant, Microsoft Windows, NTP, time

Hi folks, a lot of the time when I'm out on consulting engagements I get questions regarding how to setup network time in Windows Server 2003.
