Domain controllers not advertising as a time server - Preparing to migrate SYSVOL

Question

Domain controllers not advertising as a time server - Preparing to migrate SYSVOL

Susan Dodds 281

Server 2012 R2 DC, Server 2016 DC.

Forest level 2008 R2.

Running this cmd: Dcdiag /e /test:sysvolcheck /test:advertising

Shows both DC's aren't advertising as a time server.

Ran the following cmd's on the 2012 R2 DC and no change:

net stop w32time
w32tm /unregister
w32tm /register
net start w32time

The AD replication tool from Microsoft shows no errors.

This is in preparation of migrating SYSVOL from FRS to DFSR

Some general info

All domain members should use NT5DS domain time.
Desktops and member servers sync with any domain controller.
Domain controllers sync with PDC emulator (one per domain)
PDC emulator in child domain can sync with any domain controller in parent domain.
PDC emulator in parent domain syncs with either a hardware clock or possibly an external source.
https://blogs.technet.microsoft.com/nepapfe/2013/03/01/its-simple-time-configuration-in-active-directory/

--On PDCe--

w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /manualpeerlist:<ntp ip address> /syncfromflags:manual /reliable:yes /update
net stop w32time
net start w32time
then check
w32tm /query /source
w32tm /query /configuration

--on all others--

w32tm /unregister
net stop w32time
w32tm /register
net start w32time
w32tm /config /syncfromflags:domhier /update
net stop w32time
net start w32time
then check
w32tm /query /source
w32tm /query /configuration

w32tm /unregister removes the w32time service, so stopping it after the unregister command is kinda pointless ...

Running services when deleted are simply marked for deletion and don't actually disappear until stopped. Always a good idea to do the research before posting something you don't know.

Great information, I had the same issue!

FIX = check/change REG key value - mine was shut OFF ???? HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags

If this is 10 ... then thats the problem ... needs to be 5!!!

Changing to 5 sets the DC Flag to indicate NTP service is available.

Only took me 5 hours to find the FIX! Hope this helps someone someday ... I couldn't find any articles with this fix mentioned. I almost gave up, but found this article and voila it worked.

Found the answer in this article ... outstanding job !!!

This was the BEST article I found: https://icookservers.blog/2014/09/12/windows-ntp-server-cookbook/

There's a TON of other settings that are also defined in great detail too ... read from top to bottom!
