I'm trying to join a Windows Server 2003 R2 guest to a domain with a Windows Server 2012 R2 Domain controller server. I get the error "The following error occured attempting to join the domain "mydomain.local" the specified network name is no longer available." DNS is ok I can do nslookup just fine. I cannot access the SYSVOL or NETLOGON from the 2003R2 server, I get the same error "network name is no longer availalbe". I've disabled AV / Firewall on the domain controllers and the 2003 R2 guest. The domain functional level is "2008 R2". Is this setup not supported or does anyone know what I'm doing wrong?

EDIT: This is a new domain set up for test purposes. I successfully joined a 2008 R2 server and another 2012 R2 already.

  • doing an nslookup gives you the correct IP Address of the DC? As in, it hasn't changed since b/c of lease expiration, etc? Can you ping the guest from the DC? vice versa?

  • I know for a fact this works fine since we have 2 2003R3 servers in our environment (sadly). Double-check your DNS settings.

  • @MDMoore313 nslookup gives indeed the correct IP of the DC. And yes, I can ping successfully form 2003 R2 server to 2012 R2 and vice versa. Feb 14, 2014 at 13:54
  • Have you tried connecting to the domain with the 2012's firewall turned off?

  • @NathanC DNS settings are correct, both hostnames resolve to the correct IP address. Feb 14, 2014 at 14:01

The problem was I forgot to install SMB 1.0 on the Windows 2012 R2 server. You can do this in the "Add Roles and Features" wizard (see image below).
