Hi @Delbert Brumley Admin
Thank you for reaching Microsoft Q&A Forum!
Yes, windows server 2025 is supported to install the Microsoft Entra Connect, but make sure you select the Active Directory schema version is latest one when you install the AD in domain controller. since the windows server 2025 is new we recommend use Windows Server 2022 for production.
Before installing, please follow the Prerequisites for Microsoft Entra Connect.
Hope this helps. if this is not your case, please let me know by responding in the comments section.
