Microsoft has not tested NewSID for all deployment cloning options. For more information on Microsoft's official policy, please see the following Knowledge Base article:. Many organizations use disk image cloning to perform mass rollouts of Windows. This technique involves copying the disks of a fully installed and configured Windows computer onto the disk drives of other computers. These other computers effectively appear to have been through the same install process, and are immediately available for use.
While this method saves hours of work and hassle over other rollout approaches, it has the major problem that every cloned system has an identical Computer Security Identifier SID.
This fact compromises security in Workgroup environments, and removable media security can also be compromised in networks with multiple identical computer SIDs.
Demand from the Windows community has lead several companies to develop programs that can change a computer's SID after a system has been cloned. It is free and is a Win32 program, meaning that it can easily be run on systems that have been previously cloned. One of the most popular ways of performing mass Windows rollouts typically hundreds of computers in corporate environments is based on the technique of disk cloning. A system administrator installs the base operating system and add-on software used in the company on a template computer.
After configuring the machine for operation in the company network, automated disk or system duplication tools such as Symantec's Ghost , PowerQuest's Image Drive , and Altiris' RapiDeploy are used to copy the template computer's drives onto tens or hundreds of computers. These clones are then given final tweaks, such as the assignment of unique names, and then used by company employees. Another popular way of rolling out is by using the Microsoft sysdiff utility part of the Windows Resource Kit.
This tool requires that the system administrator perform a full install usually a scripted unattended installation on each computer, and then sysdiff automates the application of add-on software install images. Because the installation is skipped, and because disk sector copying is more efficient than file copying, a cloned-based rollout can save dozens of hours over a comparable sysdiff install.
In addition, the system administrator does not have to learn how to use unattended install or sysdiff , or create and debug install scripts. This alone saves hours of work.
The problem with cloning is that it is only supported by Microsoft in a very limited sense. Microsoft has stated that cloning systems is only supported if it is done before the GUI portion of Windows Setup has been reached. When the install reaches this point the computer is assigned a name and a unique computer SID. If a system is cloned after this step the cloned machines will all have identical computer SIDs.
Note that just changing the computer name or adding the computer to a different domain does not change the computer SID.

Video games can benefit companies by giving employees a recreational outlet to build cooperation and morale. But they can also create problems if misused. This policy will help you establish the ground rules for permitting or prohibiting the use of company systems and networks for video gaming purposes. Where gaming is allowed Video gaming is The only way it would be is if Windows ever references the machine SIDs of other computers.
Instead, you have to specify credentials for either an account local to the remote system or to a Domain account for a Domain the remote computer trusts. The remote computer never references the machine SID of the connecting computer. ThatGraemeGuy here on Server Fault agrees with me. Seriously, you don't need NewSID. Microsoft has retired NewSID on the grounds that it's not necessary.
Sysprep still gets rid of things like those pesky registry keys that interfere with WSUS, however. Microsoft does not support cloning without sysprep. I presume from your question that you're hoping to get rid of that NewSID step yay! This is true, but hopefully pointing out that NewSID has been unsupported since will also help you get rid of that unnecessary step in your rollout process.
After deployment. Common sense. If the generalization would generatea new SID, you would have to repeat it on every machine - which would sort of totally go against what the word means.
After generalize the machine is generalized and then reinitializes on next boot. So you shut down, deploy and then - the deployed images boots and generates a new SID pe machine.
