Question : Windows 2000 Pro Time and Date Lock Down

I am looking for away to lock down the time and date on a windows 2000 professional computer. The solution I am looking for needs to be able to be applied to several computers that are not in active directory. The solution also cannot rely on thrid party software solutions.

Answer : Windows 2000 Pro Time and Date Lock Down

The windows time service can be configured to do that.
With the command:
net time /setsntp:DNSName
– or –
net time /setsntp:IPAddress
you can set what the time source of the PC is.

- You can specify and external time server for all PC's, make sure they have outgoing internet access (UDP port 123)
- You can specify an internal PC as time server for all PC's. To make a PC a time server, set HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\LocalNTP to 1
You can have that one PC on its turn be synchronized with an internet time server, or just leave it's hardware clock as source for all PC's. (Wich will not be 'the' correct time, ofcourse)
