Some of the IT people overlook this SID attribute of a machine forgetting the importance of unique SID/GUID requirements.

1. Try creating a clone of VM in Hyper-V or VMware Workstation and have them in Workgroup and see if you can enable communication between two clones
2. Try join the same clone VMs into Lab based domain and see how it goes
3. With domain user accounts added in the VM’s Lusrmgr.msc, post AD join and logging into VM with one of AD account and then demoting VM from domain, and then try to do a sysprep with domain accounts still there in local user accounts, and see if you can run sysprep successfully

Please do this Labwork and comment your results…

Just a sneak peak at the SID error…
