Hi,

We want to clone/P2V a couple of our desktops, add them to our vSphere cluster and people will then RDP to them and use them for testing.  They'll be on the same prod network as the PCs we've cloned them from which will be running.

With XP we used NewSID to give the P2V'd image a new name and SID but what should we do for WIn7.  Or,is there a another/better way to do this.

Thanks

There is no requirement to change the SIDs of a Windows Machine, unless you are going to use WSUS in your network. Just make sure it has a new computer name  (different), different MAC Address and IP Address.

The Microsoft supported method of cloning is to use SYSPREP, after the clone.otherwise, after the CLONE/P2V use SYSPREP.

also make sure you are using Retail versions of Windows OS, or Volume licenses. If OEM, Activation will break and not  succeed in the VM.

Cheers. Will have a look at your articles.
So i could P2V a desktop, then clone it multiple times ins vSphere, give it a new NIC (for new MAC) remove from domain,  rename, release/refresh IPs and I'm good to go. What if we do want them patched by WSUS?

If you want to patch using WSUS you must use Sysprep.

VMware Convertor will change the Mac address, it may be easier to get your P2V VM, and then clone it X times.

I've not used Sysprep on Win7, you couldn't point me to a good article on what exactly i need to run for my situation.
Can i just run it manually from within the P2v'd/cloned VM?

Cheers

1. sysprep one machine this is your base vhd
2. create a new virtual maching using differencing disks using the base vhd
3. repeat  #2 as necessary
4. start each machine, change the computername to a unique name, activate
5. repeat #4 for each new virtual machine.

WSUS does not use SID. It uses SusClientId.

You maybe be able to delete this SusClientId using the below script.

SusClientId will get recreated.

Correct WSUS does not use the SID, but Sysprep is one of few tools, that re-creates the SusClientId.
