• Problem of time synchronization in the HP b2600 workstation.

  We have three Hp b2600 named rop11, rop12, rop13.

  rop11 is active and rop12 is passive and rop13 is autonomous.

  ROP's time synchronized with the GPS clock. But we face a problem of time synchronization.

  As we sychnisied a day after we saw a drift of about 10 seconds in rop11 and 1-2 second in rop12 & rop13.

  ntpq shows according to the attached file.

  TW file attached, one is Parallet1 where the existence of the problem and another is PArrallel2 where its not working OK.

  PL. suggest the cause and cure.

  Thank you

• Help! Window 2008 server R2 and R2 2012 window server time synchronize the difference

  Hello Sir/Madam,

  Help! I have a pair of window Server 2008 R2 and a pair of window Server R2 2012, who are the synchronization of time to one destination.

  After that time synchronization is successful, the window Server 2008 R2 clocks are still 1 second faster than those in the 2012 window servers.

  Is there anyone who got the same problem as me?

  Thank you.

  Kind regards

  You have configured in the policy of your system (System > Local > strategy system, edit, then time synchronization) and deployed this policy on the managed device?

• Guest operating system and NTP time synchronization

  Previously he had problems with operating systems using VMware tools to synchronize the time with the ESXi hypervisor. These problems are solved in 5.5 ESXi?  Is the current best practice to use an external NTP server or it's OK now to the OS to sync with invited ESXi?

  Thank you!

  I'm not aware of technical problems. If the host is synchronized correctly, you shouldn't have any problems with the client VMware Tools time synchronization. That you should keep in mind is that a guest must only synchronizes time with a single source. In an announcement which is usually a domain controller. Also mak sure you synchronize the ESXi host time from a virtual machine running on the host.

• How to disable the time synchronization in a VMware customer?

  Hello!

  Could someone please tell me how could stop a VMware customer of time synchronization? I'm using VMware Workstation 9.

  I added these settings to the .vmx file:

  tools.syncTime = "FALSE"
time.synchronize.continue = "FALSE"
time.synchronize.restore = "FALSE"
time.synchronize.resume.disk = "FALSE"
time.synchronize.shrink = "FALSE"
time.synchronize.tools.startup = "FALSE"
time.synchronize.tools.enable = "FALSE"
time.synchronize.resume.host = "FALSE"

  Unfortunately, when I start the PC it will synchronize time. If the PC is running, and I got a break, after that it will not synchronize the time, until I restart it. My hypothesis is, that in the BIOS of the client synchronizes time somehow.

  Could someone tell me how can I disable it and completely disable the time synchronization?

  Thank you!

  To start a virtual machine, it chooses the moment the host using unless you specify something with this option:

  rtc.startTime = "1089395200".

  See my notes at sanbarrow.com

  in WS 10, we have a little more settings that you may need to define - haven't tested them yet:

• Impossible to disable the time synchronization in VMWare Workstation 8.0.1

  I read 1189 KB # as well as various articles on disabling time synchronization between host and guest, but I can't seem to stop synchronization.

  I closed the comments and edited the VMX file as follows:

  tools.syncTime = "FALSE".
  Time.Synchronize.continue = "FALSE".
  Time.Synchronize.Restore = "FALSE".
  Time.Synchronize.Resume.Disk = "FALSE".
  Time.Synchronize.Shrink = "FALSE".
  Tools.Synchronize.Tools.Startup = "FALSE".
  

  But no matter what, the time of comments still synchronizes to the host after turning the power on or return to.

  I tried on the hosts Windows 2008 x 86 and Windows 2008 R2 with the same results.  I also disabled the functionality of Windows to "synchronize with a time server Internet.

  I'm using VMWare Workstation 8.0.1 on Windows 7 Pro x 64.

  Clues as to what I'm missing?

  Thank you.

  Your initial message, I found that something is different with the content of KB.

  Will keep you ' tools.synchronize.tools.startup = 'FALSE' but the KB said there should be time.synchronize.tools.startup = 'FALSE'.»

  Please copy and paste below your *.vmx file model.

  tools.syncTime = "FALSE".

  Hello

  The problem rises when the VM is restarted, which then the VM gets the  time of the ESXi server and it does not keep its previous time.

• vmmark2 - error - time synchronization failed start/finish

  vmmark2 - error - time synchronization failed start/finish returned RC = 10002, System Error 1326 unknown or wrong password username.

  I provided the correct credentials to connect to the VCserver.  Not sure why she's enclosure.

  Is the VC server credentials or the credentials of vcenter?  These two don't with the same error.

  Without a NTP server, you will need to manually synchronize things to the top and make sure that they don't automatically readjust their time.  Review the TimeChecks.txt file that is generated when executing.  This will tell you how far the individual systems are.  Each system must be within 60 seconds of the first customer.

  Thank you!

  Like James, I'm really not versed enough on AD to determine if the problem is there.

  Here as a test script that should help you to try out different options (credentials, ip, etc.) outside of the bundle, so you can speed up the trials.  I put it so its exactly like the VMMARK2.config that you sent, but it should be pretty easy for you to modify as needed.  Do not forget to leave orders STAF and run it from a shell.  Maybe a few different iterations will shed light on the problem.

• Check the configuration of time synchronization in ESX 4.1 for Windows domain

  Hello

  Sorry if this topic will cover many, but browsing the forums I found some conflicting info and thought that it easier to ask you if I had it correct.

  I'm ready to virtualize our Active Directory environment and put all our virtual machines RODCs.  We have an environment with 8 ESX hosts and vCenter 4.1.  Most VMs are Windows member servers, but also several RHEL servers and a few non-domaine joined Windows servers.  We have also two domain controllers that are already virtual machines.  I'm down to the last physical domain controller which is our role PDC FSMO server so the Master Timekeeper.

  That's how I was going to change our Setup for the services of time with all being virtual domain controllers.

  1. the virtual FSMO PDC of our clocks of field it is time via w32tm to an external time such as us.pool.ntp.org source. That's the only DC with an external time source.
  2. all the domain joined machines Windows, whether virtual or physical (servers and clients OS) get their time via the domain controllers.  PDC-> all the other DCs-> clients and member servers.  On VMS, we do not use VMTools do a time synchronization. Throughout the normal Windows AD process.
  3. all ESX hosts serve time source external PDC, described above.
  4. all the non-domaine attached (Windows or Linux) machines that are virtual machines get their time synchronization via the VMTools Sync feature.
  Have I not my correct thought and not its ok to ensure synchronization of time between the field in a virtualized ad environment?
  Thanks in advance,
  HR

  That sounds about right, and I've implemented almost identical to this designs. The key is, as you say, do not sync using the time host via VMware Tools, in particular on the role of the PDCe.

  I also usually use this method to ensure that the PDC (role 5) is the only way to an external time source:

  Yes, VMmark 2 supports vSphere and vCServer 5.0, I would recommend updating to VMmark 2.1.1 if you don't have it already done.

  No, vCServer didn't need to be in the field of mail server.

• Time synchronization error ESX and VMs despite the existence of the NTP server

  Last time the ESX Server system was wrong, and some virtual machines (windows and linux) took the time ESX as their time.

  The weird part is that these virtual machines have been synchronized with a physical server, and the time synchronization tool VMware has been disabled!

  No idea why this happens?

  Thanks in advance

  ... and the option synchronize tools vmware ESX server has been disabled

  I understand that. However, the KB article, there is a difference between 'disabled' and 'completely disabled.

• Time synchronization with host ESX to Windows start even if disabled in VMware Tools?

  Hello

  just got in trouble with a freshly installed Windows XP SP3 VM do not apply Active Directory group policies. After some research, I discovered that this happened only with VMware Tools installed.

  With VMware Tools installed, Windows events 1030 and 1097 were generated at each start (the events say that group policy processing has been abandoned and that there is a time difference between the server and the client) and group policies have been applied.

  Without VMware tools, everything was fine.

  After some additional debugging I discovered that the ESXi (4.1) server was not configured with a valid NTP server and the host time was 10 minutes behind. However, as time synchronization between the guest OS and the ESX host has been disabled in VMware tools, I couldn't imagine it was really the cause of the problem. But strangely it turned out that this was indeed the case! At every Windows startup time has been at the time of the host ESX - but only for a few seconds. This can be seen in the attached photo: initially, there are guest operating system time, and then you see the jump both ESX and then jump back to the guest operating system.

  Why does this happen? Hard, I could solve the problem in the first place by configuring the NTP server on the host, I would like to know why VMware tools change the time of the guest OS, even if it is disabled!

  Thank you

  When he put the VM must draw from somewhere and since the AI network time form more that probably not started it must draw from the host, but once the networking appears he died in the NTP source - that's why it is recommended to configure your ESXi (and ESX) to synchronize the time with NTP source.

• Impossible to disable the time synchronization

  Hi all

  I'm very new to VMware player, so sorry if this topic has jet were treated / my questions are obvious.

  I am running Windows 7 Pro as a guest in VMWare Player 3.1.0 host system is Windows XP. The client Windows 7 Pro as created directly from VMware

  Player (create a new Virtual Machine...). Everything is ok and the

  Created virtual OS with success of the DVD ISO. I want to disable the synchronization of the time of the guest computer, but I can not: opening the virtual machine (in a State of suspension), comments clock is synchronized after a few minutes.

  Here is a list of steps / attempts to solve the problem (without success):

  • I installed VMware tools, disable the synchronization of time in the menu "options".

  • I added the following to the .vmx, file as described in this article http://www.VMware.com/support/ws45/doc/new_guest_toolsconfig_ws.html :

  tools.syncTime = "FALSE".

  Tools.Synchronize.Restore = "FALSE".

  Time.Synchronize.Resume.Disk = "FALSE".

  Time.Synchronize.continue = "FALSE".

  Time.Synchronize.Shrink = "FALSE".

  • Inside "Internet time" synchronization is disabled.

  • Guest network card is disabled

  Thanks in advance for the help.

  This article is old - see more information http://sanbarrow.com/vmx/vmx-always-start-tonight.html

  you need more than two parameters since some versions - you have 5 - you have all 7

  tools.syncTime = "FALSE"
  time.synchronize.continue ="FALSE"
  time.synchronize.restore = "FALSE"
  time.synchronize.resume.disk = "FALSE"
  time.synchronize.resume.memory = "FALSE"
  time.synchronize.shrink = "FALSE"
  time.synchronize.tools.startup = "FALSE"
