I deployed three Win2008 R2 VMs from the same template and made the mistake of not using customization to change the SID. I have verified using PsGetsid that all three have the same SID. These three VMs are my domain controllers/DNS/DHCP. I found this article on how to use sysprep to change SIDs on a Windows 2008 R2 server:
Two questions:
1. Am I going to run into problems in having all three of my DCs/DNS/DHCP servers with the same SID?
2. Can I use the method shown in the above article to change the SID on two of these servers? One of these DCs hold all the roles so I would change it on the other two. I am gun shy about messing around with these machines considering their importance
