Cloned Virtual Machine on Domain

One thing I figured while cloning a VHD is that when you start the cloned VM for the first time, make sure that you do not log on to the domain. Logon to the local machine first and run NEWSID to rename the computer and assign it a new SID. Failure to do so creates multiple entries in the Active Directory with the same NETBIOS name, and you may not be able to logon to the domain from the original VPC. If that occurs, however, the remedy is to remove both machines from the domain, and then join the domain again one machine at a time (i.e. after renaming the second machine and assigning it a new SID).
