Domain member computers have a requirement to be in time sync with each other or resources will not be available.

I don't believe there is a way for your to accomplish this while the computers are on an Active Directory domain.

Found an article on internet on how we can achieve this ..I have not tested it yet:

Might need to add the following XML section to the .VMC file:



 
 
   ....
   
   
     false
   
   
   ....
 
 


Wht u think about this

I believe that is just going to disable the Virtual machine from syncing time with the host server it is installed on.

Your goal is to access a domain network resource from this virtual machine while the virtual machine date is set to another day.  I don't believe that is possible.  As soon as your virtual machine tried to connect to the domain resource while having a different date/time stamp, the Kerberos security will deny the access due to a time mismatch.

PC Rob is right,and there is a much simpler way to diablehost/guest ime syncronizartion, it an option on the VM settings in VI.

What you NEED to change is your Domain Controller.  Your ssytem is setup to enforce time restriction -- if the client is more than 30 min different fom the DC, access is blocked.  Period.

This CAN be unconfigured, one good way is to run the Microsoft Server Securtiy wizard, and configure your DC to support older OS which do not sync their clocks, this will remove that requirement and givce you a chance to look at your entire security config, since if you are asking this question in this formum, it might be a good idea to review your DC configs anyway.

If you dont want to do that, post back and we can find a silver bullet cure, but I strongly suggest you investigate the Server Security Wizard to resolve this issue

Oh yeah, its an optional windows intall , look in Add / Remove Programs | dd remove Windows components |

NO, VMware has NOTHING to do with this error, its the new security measures implemened in Server 2003, that were not in Server 2002 that are causing this.

Its a domain policy and VM ware cannot ovveride it.

You have reached the end of the solution line I think.  Either keep your VM on the correct date, or you have to disable the security settings on your AD server to ignore that issue.

Those are the only two options if you want to use a network resource on the AD.

But i would like to let you guys know, that even after changing the  dates on a physical desktop, the network drives are still accessible...We have the same domain controller, then why is doent happen on physical machine but happens only on VM machines?
