GUID/SID, Domains, NEWSid, Ghost and VMWare

If a cloned computer using a ghost image is added to a domain (captured from a baseline machine never on a domain) does it receive a new GUID/SID?  I've been running NEWSid after bringing up the cloned machines but before adding them to the domain.  It also allows me to change the computer name.  Is this extra step necessary?

With 'cloned' VMWare OSs.  Do the clones receive a new GUID/SID during the cloning process or do they need NEWSid ran as well??

the step is necessary, otherwise there will be duplicates in the network. so the nwsid is the best thing to do if you clone.

with vmware os, (ESX) you add a sysprep option to the vclient, this will run a wizard if you clone/duplicate a vm, this will run the sid change during this.

what version of vmware are u using.

The SID is a long standing myth and is explained here. NEWSID is retired and no longer available due to the author discovering it actually did nothing all these years.

Interesting article.

Yes, SID is a long standing myth if you only read the article.  I plowed through quite a few posts and very few people agreed with the writer - even though he is the NewSID guru.  NewSID may only work because we want to believe that there are issues if we don't change the SID.
