How to Generate New SID in Server 2012

This tutorial will explain how to generate a new SID in Windows Server 2012.

The System Preparation tool (Sysprep) is a technology you can use with other deployment tools to install Microsoft Windows operating systems with minimal intervention by an administrator or technician.

First, log into your Windows server. If you don’t have a windows server, get it by following this link.

Press Start+R at the same time, and it will open Run.


After, Run sysprep.exe as an administrator.

Run as an administrator

After, System Preparation Tool will open.

#1 In the System Cleanup Action section, choose :

Enter System Out-of-Box Experience

#2. In the Shutdown Options section, choose :



Click OK, and your new SID will be generated.


Once rebooted, log in again and follow the steps to change the Administrator password, Hostname, and IP Address.

You have successfully developed a new SID.

SID stands for Security Identifier, which is a unique identifier that Windows operating systems use to identify user accounts, groups, and computer accounts. It is used in access control lists (ACLs) to determine which users have access to specific resources.

There are a few explanations why somebody might want to generate a new SID in a server. One common reason is to ensure the security of the server. If an attacker gains entry to a server and can obtain the SID, they may be able to use it to gain access to other systems on the network. Generating a new SID can make it more difficult for attackers to gain unauthorized access.

There are a few different ways to generate a new SID in a server, depending on the operating system and specific requirements. One common method is to use the Sysprep tool, which is built into Windows. This tool can be used to generalize the system, remove unique identifiers like the SID, and prepare the system for cloning or imaging.

In most cases, generating a new SID in a server will not affect the functionality of the server. However, there are some applications and services that rely on the SID to function properly. Before generating a new SID, it is important to test any critical applications or services to ensure that they will continue to work correctly.

It is generally not necessary to generate a new SID in a server regularly. However, if there is a security breach or other reason to suspect that the SID has been compromised, generating a new SID can help to ensure the security of the system.

Some best practices for generating a new SID in a server include testing any critical applications or services before making the change, backing up the system before making any changes, and documenting the change for future reference. It is also principal to ensure that all systems that interact with the server are aware of the new SID.
