Domain Contoller in Hyper v

Hi All we recently Virtualized a DC, we also have an Exchange Server that is part of the Domain.

Since we have Virtualized the DC, Authentication on the separate Exchange Server fails, now I know this is because of time synchronization, if I run the following command on the exchange server

net time \\192.168.71.10 /set it all kicks into life again

can anyone tell me the steps I need to take to prevent this, I have read conflicting articles on the web but am still unsure of what to do?

No not as yet im a bit unsure of what to do could you assist?
We don't have a time Source server as stated in the article is there a way to do this using an external free source?
Most time servers are free, you could synchronize your clock against Microsoft time server if you wish (you could also sync it against universities, government agencies, etc.  I am in Canada and I am synchronizing mine against NRC.CA which stands for National Research Council).  Below are links where you could obtain IP/names for NTP servers:

http://www.pool.ntp.org/zone/@ 
http://tf.nist.gov/tf-cgi/servers.cgi
http://nrc.ca
So once I have configured the DC as an external time source what do I do with the exchange server?
Ok I am a bit lost and could do with some help
 I found the following Article

http://social.technet.microsoft.com/wiki/contents/articles/12709.time-services-for-a-domain-controller-on-hyper-v.aspx

and the first thing to do it says is add the Reg Key, when I go to the Reg Key I get Access Denied

On the DC I ran w32tm /query /source just to see what the source was and got The Service has not been started.

So I go into Services and realised the Windows Time service is not started when I gi to start it I get Access Denied????

can any one help
What account is the time service running under? It should be "Local System"
If you have UAC enable then ensure to start cmd.exe or regedit.exe running as administrator.
