Hello @Thomas Reminga,
Thank you for posting your query on Microsoft Q&A.
Based on your description, I understand that you want to know deleting Microsoft Entra Domain services will have any impact on any physical windows 11 devices which are enrolled as Microsoft Entra joined devices in Entra ID. Deleting AADDS (Azure Active Directory Domain Services) should not affect your end-user devices that are directly joined to Azure AD/Microsoft Entra ID.
Microsoft Entra Domain Services provides managed domain services such as domain join, group policy, lightweight directory access protocol (LDAP), and Kerberos/NTLM authentication.
In your setup, it sounds like AADDS was primarily used to allow your AVD hosts to join the Azure AD environment, which is common for scenarios involving Azure resources that need domain-like functionality. Since you’ve already decommissioned the AVD environment, AADDS is no longer serving that purpose.
End-user devices joined to Azure AD (via the standard Windows 11 process) have no dependency on AADDS. Their trust relationship is directly with Azure AD, not AADDS. So, deleting AADDS won’t break their connection or impact their functionality.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
