Renaming the Computer - questions

[NiklasJegg1]

Hi, how do you handle Certificates when renaming the PC?

For example i am Hybrid Joining the PC. The Certificate enrollment happens per GPO so the first Certificate is only valid until Renaming.
I know that "certutil.exe -pulse" refreshes it but i have to Reboot the PC and after that i lose connection (obviously because the certificate won´t match)

And another question: I am currently querying the PC name based on the Serial from my own Sharepoint List where all Inventory resides. (i connect to the SPO list with a certificate packed into my win32 App)
Do you know if i somehow can authenticate with the Computer Account to the Sharepoint list?

Thanks and BR
