After you run the below command to set the registry and restart the time service, it fails the time service advertising:

 

w32tm /config /syncfromflags:domhier /manualpeerlist:pdc /reliable:yes

 

If you use the below with /reliable:no stating it is NOT a reliable time source, it works correctly and advertises.

 

w32tm /config /syncfromflags:domhier /manualpeerlist:pdc /reliable:no

 

Am I interpreting this command incorrectly, or is the switch backwards?

HKLM\system\currentcontrolset\services\w32time\

 

\config\AnnounceFlags = A (10) – causes the server to announce itself as a time server (/reliable:no)

\Parameters\NtpServer = pdc – Uses the domain pdc emulator to sync time,. (manualpeerlist:pdc)

\Parameters\Type = NT5DS – NT5DS = synchronize to domain hierarchy [default] (/syncfromflags:domhier)

And the second obvious question, have you taken a trace with something like ethereal? I’m sure it has an (S)NTP protocol analyzer to look at the packets and tell you if it’s a network issue, a pdc issue or a host issue (or some combination thereof). Send a trace back (or privately if you prefer) of the w32tm /resync packets and I can look at it if need be….

 

Thanks,

Stupid question, ntp port is opened between them? Since this is the only two servers in the site, is there any ipsec rules etc?

 

 

 

Thank you and have a splendid day!

Subject: [ActiveDir] Time Service Errors

I’m having a problem with time services in a particular root domain on 2003 sp1.

 

Initially, all 4 dc’s were not advertising as time servers, I was able to fix that issue.

The 3 dc’s will not do a resync with the pdc emulator when I run “w32tm /resync”

 

C:\>w32tm /resync

Sending resync command to local computer...

The computer did not resync because no time data was available.

 

When I do the below monitor command, I get:

 

C:\>w32tm /monitor /domain:r2

LIVP3R2RDOM01.r2.xxx.net [172.20.225.239]:

    ICMP: 0ms delay.

    NTP: -6.5469435s offset from FTWP3R2RDOM02.r2.xxx.net

        RefID: 'LOCL' [76.79.67.76]

LIVP3R2RDOM02.r2.xxx.net [172.20.225.240]:

    ICMP: 0ms delay.

    NTP: -5.9396763s offset from FTWP3R2RDOM02.r2.xxx.net

        RefID: 'LOCL' [76.79.67.76]

FTWP3R2RDOM01.r2.xxx.net [10.175.36.11]:

    ICMP: 39ms delay.

    NTP: -0.0000685s offset from FTWP3R2RDOM02.r2.xxx.net

        RefID: 'LOCL' [76.79.67.76]

FTWP3R2RDOM02.r2.xxx.net *** PDC *** [10.175.36.17]:

    ICMP: 39ms delay.

    NTP: +0.0000000s offset from FTWP3R2RDOM02.r2.xxx.net

        RefID: FTWP3R2RDOM01.r2.aig.net [10.175.36.11]

 

The PDC is in synch with the other server in it’s site, the 2 not in it’s site will not sync, all get the error on a resync.

 

I have a case open with MS, however they can’t find a way to fix it.

 

Help,

 

Andrew
