Configure DC to synchronize time with external NTP server

How do I configure time in my Active Directory?

Well, it's simple! Normally it should be set correctly if we don't modify it in purpose,

Otherwise, we do provide some tools for that: w32tm.exe command-line utility and GPO. we are going to look here w32tm whihc is very easy.

• Using w32tm.exe

Run the following command on the PDC emulator:  

If you have multiple domain controller and don't know which DC holds PDC role then use following command: netdom /query fsmo

w32tm /config /manualpeerlist:timeserver /syncfromflags:manual /reliable:yes /update

(where timeserver is a –space delimited– list of your time source servers)

BACKUP & RESTORE OF DHCP SERVER

Manual DHCP server backup

You can also run backups manually through the DHCP management console. This feature can be useful if you intend to make major changes to your DHCP settings. You can back up the database to a location other than the default folder. Note that this won’t change the location of the regular automatic backups. This setting can only be changed in the Windows Registry with the BackupDatabasePath parameter.
