We have a Server 2008 R2 server running DNS, AD, GC, GAL, etc that I would like to virualize. Can I use sysinternal VHD software to do that then just start it up on my 2012 host? Of course I would disconnect the hardware version first. How much time can lapse between creating the VM and firing it up before changes in AD would case issues?

As long as you take your server down while creating the VHD file Disk2vhd should do a perfect job. I have done it a couple of times and it worked well. The time to convert your physical machine depends on your harddrive size. Some of the 2003 servers I have migrated had 250GB SATA drives and took ~7 hours. Plus one more hour to get them running in Hyper-V (config settings).

What is the Hypervisor?

I would recommend creation of new VM, and then Promote to a DC, transfer all the FSMO roles.

Using Disk2VHD, the image (vhd) will be out of date, by the time it's finished writing compared to the DC.

We do not have a big network, one domain, about 220 user accounts plus the usual misc accounts. I ran the VHD once and it took about 90 mins to make the image. We are not a 24 shop so I could probably do this one weekend evening with little impact...

If you are going to do a "hot" clone, make sure ALL the services are stopped and set to Manual!

Then start the services, and set to automatic

You mean stop all services on my real box before cloning, make the clone, start it in Hyper-V, then restart the services that should be running?

That's correct, to prevent a corrupted, out of date Active Directory Database, DNS, DHCP etc

@LarryDAH that is what I meant with "take the server down". Stop any activity on the server. For my customers I did it at weekends while nobody was working and no client accessed the server. No change of data may occur.

if going to migrate to any flavor of vmware, you can use "VMware vCenter Converter Standalone Client". a very powerful tool, having many options as how the virtual machine should behave. you can get it here.

https://my.vmware.com/web/vmware/info/slug/infrastructure_operations_management/vmware_vcenter_converter_standalone/5_1#product_downloads.

I have done many live active directory physical to virtual migrations, without facing a single issue.

one example:-

I migrated 2008 R2 domain, with about 100 users using above tool, within 35 minutes.
the server was an old hp dl380 G5 with 2 dual core processors, 3x 72 GB SAS Raid 5, and just 4gb of Ram.

After conversion just disabled the nic of physical server and started the vm,  verified LAN settings of VM first, brought it online and it worked without any hiccup. (may have to).

and since you are not a 24 hrs shop, so you may do it on weekend evening.
