I'm having a problem with DHCP.  Specifically, sending the time to clients.

We have a server that does a few small things like DHCP.  Its system time appears fine.  Within the DHCP scope I've added that server's IP address as the Time Server (004).  Workstations in the building are all about 10 minutes behind the DHCP server.

This seems simple enough, is there something I missed?

    If you have a domain you don't need to set this property on DHCP. Always you start any computer, it sicronizes to the Domain Controller. So, try deleting 004 property

    Under administrative tools -> services.  Make sure that the Windows Time service is running.  If it is, you may have to edit a registry key to make it set itself to use it's internal clock and announce itself to all clients......


    1. Click Start, click Run, type regedit, and then click OK.
    2. Locate and then click the following registry subkey:
    3. In the right pane, right-click AnnounceFlags, and then click Modify.
    4. In Edit DWORD Value, type A in the Value data box, and then click OK.
    5. Quit Registry Editor.
    6. At the command prompt, type the following command to restart the Windows Time service, and then press ENTER:
    net stop w32time && net start w32time

    You can manually resync the time on workstations using the following command:
    1. To open a command prompt, click Start, click Run, type cmd, and then click OK.
    2. Type w32tm /resync, and then press ENTER.

    One thing I did notice is that the date has to be set correctly on the workstations.

    If this is old NT days, I did this with the user login script:

    net time \\servername /set /yes

    Ok...  The DHCP server is not the AD master.  The time on the AD master is off so I corrected that and nuked the Time Server from DHCP.
