Good timekeeping might seem like a nice feature, but with computer security, it is a must. Both servers must keep themselves within 5 minutes of each other on their clocks otherwise the security communications will fail. To achieve this, we will synchronize the SBS 2003 system to the SBS 2008 system. While the SBS 2008 system is not yet present, this command is needed before the two systems start communicating, which will happen during installation of SBS 2008. To prepare for this, you will need to enter the following commands into a Command Prompt by running cmd.exe. The w32tm command re-configures the time synchronization service and tells it to synchronise to the Active Directory domain. Starting and stopping the w32time service will re-synchronize the time to the new settings.
w32tm /config /syncfromflags:domhier /reliable:no /update net stop w32time net start w32time
You should see the output like this:
