Solution

Note: Any one of the things below can cause this problem, I suggest you retry running dcdiag after each step until it runs without error.

1. In a windows domain, clients normally get their time from the domain controller that holds the PDC Emulator role. Locate that server and log on.

Locate your FSMO Role Servers

2. Now configure your PDC emulator to get its time from a reliable external source.

Windows - Setting Domain Time

3. If you have got this far, then should already have the windows time service running, check!

Windows Time Service

4. From command line, remove and reinstall the Windows time service with the following two commands.

w32tm /unregister<br />w32tm /register

Note: It's not unusual to see the following error after you issue a 'w32tm /unregister' command,

Error The following error occurred: Access is denied (0x80070005)

Windows Time Service

If this happens don't panic, open the services console (Press F5) and the Windows Time Service may have disappeared (if so re-register it). If not manually stop the Windows Time service and try to unregister again, then re-register.

WARNING: After doing this, you will need to set the time service to get reliable time from an NTP External Server again.

5. Press Windows Key+R > regedit {enter} > Navigate to the following registry key;

HKLM > System > CurrentControlSet > services > W32Time > Parameters

Ensure the Type value it set to NTP, the restart the Windows time service and check again.

Windows Time Service

5. Whilst still in the registry editor navigate to;

HKLM > System > CurrentControlSet > services > W32Time > Config
Set the AnnounceFlags value to 5.

NTP AnnounceFlags

6. Whilst still in the registry editor navigate to;

HKLM > System > CurrentControlSet > services > W32Time > Time Providers > NtpServer

Make sure the Enabled value is set to 1 (one).

NTP Enabled

7. If the problem persists, on the PDC Emulator run gpedit.msc > Navigate to;

Computer Configuration > Administrative Templates > system > Windows Time Service

Make sure 'Global Configuration Settings' is set to 'Not Configured'.

Windows Time GPO

Navigate to;

Computer Configuration > Administrative Templates > system > Windows Time Service > Time Providers

Make ALL the settings are to 'Not Configured'.

Windows Time GPO Not Configured

If you changed anything, run 'gpupdate /force' and try again.

8. On the PDC Emulator, Open a command window (Note: You must Run as Administrator!) > In the Computer Settings section locate all the policies that are applying to the server.

Note: As a shortcut to find the offending policy, you could run 'gpresult /v > c:gpresult.txt' then search that text file, for any instance of w32tm, (here's an example).

GPResult

As above navigate to;
Computer Configuration > Administrative Templates > system > Windows Time Service

Make sure Global Configuration Settings is set to 'Not Configured'.

Group Policy NTP Server Settings

Navigate to;

Computer Configuration > Administrative Templates > system > Windows Time Service > Time Providers

Make ALL the settings are set to 'Not Configured'.

Windows Time GPO Not Configured

If you changed anything, run 'gpupdate /force' and try again.
