virtual dc clock are skew

We are introducing a new virtual dc 2008 in a 2003 environment, after promoting the 2008 standard server we got this errors, new dc cannot replicate with old 2003 dc.

When i open the active directory domains and trusts show the following: the configuration information describing this enterprise is not available. The clocks on the client and server machines are skewed.
event id 24: time provider ntp client: no valid response has been received from domain controller.
event id 5: the kerberos client received a KRB_AP_ERR_TKT_NYV error from the server host/domain controller.com
event id 1058: the processing of group policies failed. Windows attempted to read the file froma  domian controller and was not succesful.

This vm is in a datacenter 2012 server.

I recommend configuring time synchronization between the guest virtual machine and the virtual host. Ensure the host is set up get it's time from an authoritiative NTP time server. That keeps them in sync.

What is host ...VMWare or Hyper V
You need to disable time sync between Host and client
You need to make sure few things that your PDC role holder is conkfigured as authoritative time source  and Rest DC's are getting time from PDC  refer my article at bottom to configure the same

Refer below link for Hyper V

Refer Below link for Vmware

I set the same time in the datacenter 2012 hyperv server and the vm server 2008, we disabled the time sync between host and client and still have this errors.. Ill change the parameter value "partner clockk skew in minutes" to 1, now I can open sites and services.
My hyperv host is in domain 1 and my vm is in domain 1, if I configure a new vm server on domain2,  whatproblem could I have with the time or replication?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I'll wait some time to see if replication works with this change in the parameter clock skew value.

NOw the old DC 2003 and new 2008 seems that are replicating, just one question.
We disable the time sync between the host and the client, should we try to enable this option again? 2003 dc is my pdc authoritative time source.

You may try...but revert it once you are out of this mess...

Its not recommended to sync VM host and guest systems

ZenVenkyArchitectCommented:
No, any machine in the domain shall sync with PDC for time synchronisation and PDC shall sync with external time source like time.windows.com / pool.ntp.org. This is how the structure should be, if not Global catalog and Kerberose will fail to advertise. So do not make machine to sync with host machine. However you can check these settings by using w32tm /query /source. This command will tell you from which source machine is getting time sync.

Hope this helps you..
