W32tm always on "Local CMOS clock" on virtual domain controller - cannot change to NTP server

The domain controller (Server 2012R2) is hosted on Hyper-V (Server 2012R2). It is a PDC.
- firewall disabled
- cleaned up w32tm:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time
- applied ifixit from http://support.microsoft.com/kb/816042 to enable external ntp server de.pool.ntp.org
- disabled
VMICTimeProvider in registry
(HKLM\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\VMICTimeProvider\Enabled = 0)
I can manually query the ntp server de.pool.ntp.org:
w32tm /stripchart /computer:de.pool.ntp.org /samples:5 /dataonly
de.pool.ntp.org wird verfolgt [131.188.3.221:123].
5 Proben werden gesammelt.
Es ist 24.04.2014 10:07:36.

But still, w32tm does NOT query the ntp server:

Hi rosch,
Based on your description, please check if disable the "Time synchronization" Integration service. Please refer
to the following operation.
In Hyper-V Manager, right click the DC and select “Settings…”.
In the left panel of Settings, navigate to Integration Services and click it.
Then in the right panel, please uncheck Time synchronization.
By the way, please check if can connect to the time server and UDP port was opened for NTP.
If any update, please feel free to let me know.
Hope this helps.
Best regards,
Justin Gu

W32time source showing as Local CMOS clock

I have 3 virtual servers, all on different hosts, which are currently showing the wrong time. All other machines on the Domain get their time from the Domain Controller.
I have only been making changes on 1 server to ensure that this works. Originally the server was showing as getting its time from the host machine (VM IC Time Synchronization Provider). I then attempted:
w32tm /config /syncfromflags:domhier /update
Stopped and started the w32time service, then checked the source again. This was then showing as local CMOS clock.
I have tried several things, including setting a peer list with just the required Domain Controller, but the source remains as CMOS clock.
I've switched Time Integration services off on the Host, which I understand is not an ideal thing to do, but I'm at a loss.
Please help

I suspected some issue with AV so uninstalled.
To resolve the Access Denied I followed these steps:
stop w32time
w32tm /unregister
reboot
regsvr32 /u w32time.dll
w32tm /register
sc query w32time -- you should see that the service is set to
shared mode -- this is presumably how it should be -- if you try to start right now, you'll get the expected 1290 SID-related error
reboot
w32time should now automatically start at boot up and be running -- that was my result -- it's running as shared, started on its own, and I can do the w32tm /query commands successfully
After rebooting the time service started.
I then repeated the steps:
net stop w32time
w32tm /config /syncfromflags:manual /manualpeerlist:"0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org"
w32tm /config /reliable:yes
net start w32time
w32tm /query /configuration
And all worked. I'll wait a short while to see if this fixes the issue. I also have am SA case with MS so will confirm fix when resolved.

Cannot get Guest Services to Start on Virtual Domain Controller

I'm running System Center 2012 SP1 Version 3.1.6018.0
Guests all run Server 2008R2 SP1
I'm having a weird issue when trying to install guests services on a domain controller. On all of the virtual machines of the host, when trying to deploy the guest agent, it fails on all machines with the same error:
Error (2940)
VMM is unable to complete the requested file transfer. The connection to the HTTP server XXXXXXX could not be established.
Unknown error (0x80072ee2)
Recommended Action
Ensure that the HTTP service and/or the agent on the machine powstorehv1.gicw.org are installed and running and that a firewall is not blocking HTTP/HTTPS traffic on the configured port.
I have confirmed that there is no firewall blocking the process so in order to bypass this, I decided to just install the guest agent manually. This worked on all of the virtual machines on the host except for the one that is a Domain Controller.
At the point when it tries to start the service it gives me the following error:
Service 'Microsoft System Center Virtual Machine Manager Guest Agent' (ScvmmGuestService) failed to start. Verify that you have sufficient privileges to start system services.
I have tried with and without UAC enabled and I always run the MSI from an elevated command prompt. I've tried with and without MSIEXEC as well. I have Enterprise and Domain Admin privileges as well and have even tried with the domain administrator account.
At this point I'm not sure why I do not have sufficient privileges to start the service on a Domain Controller but I do understand that permissions are different due to its nature.
Any ideas around this either by installing through SCVMM or manually? Thank you in advance for your time!

Clock setting will be cleared by reload with "ntp server" configuration?

Hi,
I have configured 7204VXR (NPE300) processor with IOS Version 12.1(9) as "ntp server", and the clock settting have not been cleared by system reboot. I remember that the manual clock setting is cleared by reload or power off and on of the device.
Clock setting will not be cleared by reload or power off and on if the device is configured as "ntp server"?

Windows domain controller in a virtual machine: how dangerous is saving its state for a short period of time?

I have a Windows Server 2012 R2 virtualization cluster. All the hosts are connected to an external storage system, and virtual machines' files are stored on external volumes (CSVs). All the hosts and virtual machines are a part of the same AD domain
(mixed Windows Server 2012 RTM / 2008 R2 domain controllers). All the domain controllers are running in the virtual machines on the hosts of this cluster.
To prevent problems when all the hosts are turned off and then on simultaneously (for example, because of a power failure) all the domain controller VM files has been placed on local disks of the virtualization hosts (not on the Cluster Shared
Volumes). As Hyper-V services don't depend on other Windows Server services (except its networking components), it means that my domain controllers can always start, providing the virtualization host can start at all. However, it also means
that those DCs cannot be (quickly) migrated to other hosts while their current hosts are being rebooted. So if I need to reboot a virtualization host to install new updates, for example, I have to shut down the corresponding DC, reboot the host
and wait for the DC to finish cold boot and come back online. It means some interruption of service for our users, which, in turn, requires me to perform the reboots late in night.
The downtime can be significantly decreased by saving the state of the VM in which the DC is running. However, all the articles I've found on the Internet strongly recommend against it. I'm trying to understand why this recommendation was issued in the first
place. However, I'm unable to find a clear explanation. I've found some statements that saving state of a DC can cause serious AD replication problems because of tombstoning, and that the password of a DC computer account may be changed
while the DC itself stays in the saved state, which could prevent the DC from connecting to the domain after its state has been restored. However, those considerations are non-significant when we discuss a short-time
(5 to 10 minutes) saved state.
I work with AD and virtualization long time, and I fail to see any danger in saving state of a DC for several minutes. In my opinion, after its state has been restored it would simply replicate all the AD changes from other DCs, and that's all.
What's your opinion?

Hello,
as stated in "http://technet.microsoft.com/en-us/library/virtual_active_directory_domain_controller_virtualization_hyperv(v=ws.10).aspx"
Operational Considerations for Virtualized Domain Controllers
Domain controllers that are running on virtual machines have operational restrictions that do not apply to domain controllers that are running on physical machines. When you use a virtualized domain controller, there are some virtualization software features
and practices that you should not use:
Do not pause, stop, or store the
saved state of a domain controller
in a virtual machine for time periods longer than the tombstone lifetime of the forest and then resume from the paused or saved state.
This may sound as it is supported to store it for shorter times and use it.
BUT recommendation also from the Hyper-V Program manager in
http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/11/24/the-domain-controller-dilemma.aspx recommends against using them.
Also best practices

Connecting Virtual Machine to physical Domain Controller

Hello,
I have a Hyper-V environment set up. My virtual machines are on my domain controller. I would like to connect these virtual machines onto the domain controller I am hosting them on. I have tried however I always get the error saying the domain controller
cannot be contacted.
Thanks in advance,
Maksim Richards

http://blogs.technet.com/b/jhoward/archive/2008/06/16/how-does-basic-networking-work-in-hyper-v.aspx is a good article that explains the basics
of Hyper-V networking. What you are describing generally comes down to understanding the basics and getting your virtual networking switch(es) properly configured. When it comes to networking, IP is the same whether using physical or virtual machines.
You have to ensure that you have the proper paths in place that allow the communications to take place.
As for support of Hyper-V on a DC, I've not seen that it is unsupported. Bad idea? Yes. Recommended practice? No. Would I do it? No. Should it work? Absolutely. Supported? I haven't seen a Microsoft
statement on that.

Mailman virtual domains configuration - Anyone has been successfull?

Hello,
Is there any one out there that has manage to configure Mailman to work with virtual domains in a Mac OS X Server 10.3.9 enviroment??
Anyone??
I've tryied every setup and read everything in the web about postfix and mailman and I just cant get it to work.
If there is anyone out there that could show me his configuration I would mostly greatfull.

If I keep the aliases and the virtual-mailman hashes
in the postfix configuration I can have lists running
for local and virtual domains, right?
And we can have lists with the same name? And even
with the same name of the users in WG?
Once again, you can have the same name, be it for a user, be it for a list only ONCE per domain. A list and a user address are the same thing to postfix (they only difference is that a list adress is aliased to a mailman script). So they cannot exist twice in the same domain, but they can coexist in seperate VIRTUAL domains. Not in local host aliases.
In order to this works I must have in SA, Mail,
Advanced Settings, the virtual domain listed in the
local host alias?
Absolutely NOT! Virtual domains and local host aliases must be kept separate.

Yes, you can.
You will need to configure the virtual network switch as either internal or external.
Then, you'll need to specify the IP address of the virtual Domain Controller as a DNS Server on the Windows 8.1 device.

Windows Time "Allowing" the OS Kernel to sync to CMOS clock after 24H of no valid time sync

Hello,
I have been observing the following scenario with the following environment:
Windows 2008 Server R2
Not part of a domain
CMOS always clock drifted and not sync'd from the OS NTP Aware time.
1. Assume Windows Time has a problem syncing with a time source and produces the following when asked "w32tm /query /status /verbose":
Leap Indicator: 0(no warning)
Stratum: 3 (secondary reference - syncd by (S)NTP)
Precision: -6 (15.625ms per tick)
Root Delay: 0.2028500s
Root Dispersion: 7.8420074s
ReferenceId: 0x413738CE (source IP: 65.55.56.206)
Last Successful Sync Time: 2/1/2014 2:33:18 PM
Source: time.windows.com,0x9
Poll Interval: 10 (1024s)
Phase Offset: -0.0260539s
ClockRate: 0.0155992s
State Machine: 2 (Sync)
Time Source Flags: 0 (None)
Server Role: 0 (None)
Last Sync Error: 2 (The computer did not resync because only stale time data was
available.)
Time since Last Good Sync Time: 85499.5378040s
2. When "Time since Last Good Sync Time" arrives at the value 86400 (24H) an event log message such as the following is registered:
The time service has not synchronized the system time for 86400 seconds because none of the time service providers provided a usable time stamp. The time service will not update the local system time until it is able to synchronize with a time source. If the
local system is configured to act as a time server for clients, it will stop advertising as a time source to clients. The time service will continue to retry and sync time with its time sources. Check system event log for other W32time events for more details.
Run 'w32tm /resync' to force an instant time synchronization.
3. If the debug log of windows time was enabled with all the events (0-300) using "w32tm /debug .." The following records can be found in the log at the time:
- W32TmServiceMain: timeout
- ClockDispln GoUnsyncd: SetUnsync: LI:3 S:0 RDl:2184500 RDs:78611726 TSF:0x0
ReleaseClock2CMOS
- Logging warning: The time service has not synchronized the system time for 86400 seconds because none of the time service providers provided a usable time stamp. The time service will not update the local system time until it is able to synchronize
with a time source. If the local system is configured to act as a time server for clients, it will stop advertising as a time source to clients. The time service will continue to retry and sync time with its time sources. Check system event log for other W32time
events for more details. Run 'w32tm /resync' to force an instant time synchronization.
- W32TmServiceMain: waiting 642.223s
4. When the above occurs, we have observed that the OS Kernel would begin syncing to the underlying CMOS clock when they are different from each other in more than 60 seconds. The sync would occur on the next "sync point" which will arrive. A "Sync
point" is the end of a 60 minute cycle, counting from boot time and repeating.
Note: The CMOS clock could be off in more then 60 seconds for example when it's battery is dead, or on a virtualized environment under some conditions. (If anyone is interested in more details, please ask in the comment)
My Questions:
a. Parts of this behavior are well documented - can anyone confirm my analysis of the situation is correct?
b. Does anyone have knowledge of the term "ReleaseClock2CMOS" which appears in the Windows Time log? What exactly does it mean?
c. Under which conditions will the kernel avoid syncing to an underlying 60 seconds-off CMOS clock? Under which conditions will it sync (aside from what i described)?
Any info would be appreciated.

Hi,
Thank you for your question.
I am trying to involve someone familiar with this topic to further look at this issue. There might be some time delay. Appreciate your patience.
Thank you for your understanding and support.

10.4.3 Local Host Aliases vs. Locally Hosted Virtual Domains

We had been running 10.4.1 for about eight months with no problems.
1) Under the Local Host Aliases setting in Server Admin (Mail, Settings, Advanced. Hosting) we had only "localhost" listed. All the other virtual domains we hosted email for were listed under Locally Hosted Virtual Domains.
2) We added all mail users via WGM and only listed one shortname without the "@domainname.com" suffix. I.E. "user1".
3) All mail account aliases are handled by editing the /etc/postfix/virtualaliasmaps.
A few weeks ago, we upgraded to 10.4.3. All mail was being rejected with an unknown user message. Checking forums around the net, we saw a post which suggested that all domains previously listed only under Locally Hosted Virtual Domains should also be added under Local Host Aliases for 10.4.3 via Server Admin.
We did this and all mail began working OK as before the upgrade. However we are getting log entry warnings everytime an email is processed:
postfix/trivial-rewrite[3921]: warning: do not list domain oneofourdomains.com in BOTH mydestination and virtualmailboxdomains
I'd like to straighten this out so everybody is happy and no more log warnings occur.
However, we don't want to:
1) remove the virtual domains from the Locally Hosted Virtual Domains entries and have them only under Local Host Aliases since there are mail aliases with the same name under different domains, and
2) we don't want to have to go into WGM and add a domain suffix to each shortname
Does anyone know what changed between 10.4.1 and 10.4.3 and why? More importantly, how do we best go about correcting this situation. Or is this an Apple bug that will be fixed in the future and we can live with the log warnings until then?
We've searched all the posts in different forums and haven't seen anything that addresses this problem directly.
Thanks in advance for your help.

W32tm always on "Local CMOS clock" on virtual domain controller - cannot change to NTP server
