I had prepared a virtual machine with windows server 2012R2 operating system and created multiple copies of that virtual machine to use further for other applications. From that multiple copies, I used one virtual machine for Active Directory (MyRetail.com) and one for the Application Server. When I tried to join the application server virtual machine to a domain controller (MyRetail.com) it got failed with below error.
As per the error, I understand that SID is same in application and active directory servers. That’s the reason application server not connected to Active Directory.
Resetting SID in the Application Server resolved the issue.
How to Reset SID ?
- Click on start button and Type ‘RUN’
- In Run Prompt type ‘%WINDIR%\system32\sysprep’
- Double click on ‘sysprep’ and check ‘geberalize’ checkbok as per below image.
- After some time server will be restart automatically.
Note: Once the application server automatically restarted network adapter settings, host name, username, password and more will be reset.After SID reset done, I could able join application server to active directory.
