@Sameh Mohamed Atya Aglan Thank you for reaching out to us, As I understand you are trying to upgrade Azure AD Connect to the latest version, during the process you encountered this error b891884f-051e-4a83-95af-2544101c9083, does not exist in the current Azure AD Connect configuration.
Could provide more details on this error ? was the OS upgrade performed on the same server ?
Help me with the environment details like OS version ? Azure AD Connect version ?
Consider a swing migration approach (in few scenarios like this one an in-place upgrade can impose a considerable risk to production in case there's an issue while upgrading and the server can't be rolled back) - https://learn.microsoft.com/en-us/azure/active-directory/hybrid/connect/how-to-upgrade-previous-version#in-place-upgrade:~:text=Connector.GenericLdap.dll%22.-,Swing%20migration,-For%20some%20customers
Let me know if you have any further questions, feel free to post back.
