Time is money….
So it’s a good idea to a sync your PDC emulator against an NTP server. So that you have right time on your servers and clients.
On your PDC emulator start CMD and write
net time /setsntp:ntp.your-ntp-provider.com [enter]
net stop w32time [enter]
net start w32time [enter]
w32tm /resync [enter] the result should be “Command completed successfully”
If you get any problems with the resync check so that your firewall allows traffic out on port 123.
