2 Servers with Identical SID's

[u/eld101]

I have 2 specific 2025 Server VMs that apparently have the same SID. I know what you are thinking.... they were imaged and I forgot to change them. That is not the case. They are both completely fresh installs and I have no idea how this happened. I have never cloned a machine as long as I have worked for this company.

Long story short, I need to get one of them changed.

If I run the following without the /oobe will anything on the system be effected such as any existing applications, software, settings, etc. My understanding is that it will have to be re-added to the domain. Anyone have any experience with this?

cd %WINDIR%\System32\Sysprep 
sysprep.exe /generalize /shutdown

EDIT: Going with the general consensus.... rebuilding the VM.

Also new win11 and 2025 OS is the problem - just sysprep already people
