Joining Windows 2003 to Windows 2016 Domain

Question

Can Windows Server 2003 members join an AD domain functional level Windows 2016? I am getting errors when I try to join a Windows Server 2003. Do I need to re-enabled SMB v1.0 on the DCs in order to accept the membership? Thank you

Answer 1

Hi,

You can join windows 2003 to a domain with functional level Windows 2016.
Windows 2003 doesn't support SMBv2, so you have to enable SMBv1.
For your information, Windows 2003 is out of support , I recommend you to install a server using a supported operating system and avoid enable a weak protocol like SMBv1 and RC4.

Should not be a problem. I'd check the domain controller and problem member both have the static ip address of DC listed for DNS and no others such as router or public DNS.

@Dave Patrick , the question still remains if I need to disable SMB1 on the DCs running Windows Server 2019 with the dom and forest functional levels as Windows 2016. Thanks
