Why you are wanting to set this reg value? Servers/workstations get there time from the Domain Controllers and the Domain Controllers get their time from the PDC holder. You should not need to configure this option in the registry. If you are using VMware and the clients and getting the time source from the Hosts you can simply either configure the host to get the Time from the PDC or you can disable the clients from getting time source from the Host server that they are on and they will contact the DC directly to get the time.

However, that being said you can use Group Policy Perferences to accomplish this. Refer to the below link which outlines this clearly.

I decided I wanted to delete the registry value and then add the correct registry to point the Virtual Machine to sync with the hosts.

I am not able to get the registry to delete however.
Here are the steps. Not sure what I am doing wrong.
See attached screen shot of the Group Policy Management console and what I added.

Very helpful. Come to find out my VMs were pulling their time from the WYSE Device Thing Clients and it couldn't access the correct config file location. Although your solution changed the IP address via group policy it ultimately wasn't my issue. It wasn't until I changed the config file and pointed the thin clients to the correct file server did the time pass thru.
