Domain joined machines get time from domain controller (PDC Emulator) by default, but machines on workgroup need to be configured manually to get time from PDC Emulator/NTP Server.
Below are simple set of commands to configure the same.
w32tm /config /syncfromflags:manual /manualpeerlist:YourNTPServerIP
net stop w32time && net start w32time
w32tm /config /update
w32tm /resync /nowait /rediscover
w32tm /query /status
On windows 2003/XP, try below command to query time source.
net time /querysntp
the registry key Type = Nt5DS means synchronize to domain hierarchy by default.

If facing sync issues with domain controller, open UDP port 123 on firewall, to test connectivity of UDP port, download portquery from microsoft and try this command (portqry.exe -n yourDCname -e 123 -p)
Execute below commands:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
w32tm /config /syncfromflags:DOMHIER /update
w32tm /resync
w32tm /query /status
