Domain Controller is a physical server running Windows Server 2012 R2. FF Level is 2008 R2, DF Level is 2012 R2. However, I found a MS article that states XP is fully compatible with even a 2012 R2 FFL. This issue is only affecting Windows XP (and older) VMs. Exact error when I try to join a machine to the domain is:

The following error occurred attempting to join the domain "MyDomain": The specified network name is no longer available.

Troubleshooting steps attempted thus far:
- Rebooting the DC
- Re-enabling SMB1 and rebooting the DC (was already enabled)
- Restarting NETLOGON service on DC (no issues) and on XP VMs (does not stay started)
- Running DCDIAG (all tests pass)
- Disabling IPv6 on the DC
- Disabling ISATAP NIC adapter (hidden device) in DevMgmt.msc

Here is the output from DCDiag /v

At this point I am completely out of ideas? What could this be, a NTLM issue?

    Disabling IPv6 on the DC. Disabling ISATAP NIC adapter (hidden device) in DevMgmt.msc. Those last two seem like pretty random things to do. Additionally, you should never disable IPv6. Furthermore, how did you disable IPv6? If you merely unchecked it in the properties of the NIC then you didn't disable it, you simply unbound it from the NIC. Have you run the relevant BPA's on the DC? How about the event logs on the DC? Anything of note? – joeqwerty Jan 5 at 18:03
  • Are you sure that the network configuration done in the XP VM is correct? Can you check if DNS settings point to DC(s) having DNS roles. – Am_I_Helpful Jan 5 at 18:12
  • I agree with @Am_I_Helpful, check DNS first. Also, check NETBIOS/WINS is properly working. – RobbieCrash Jan 5 at 18:52
  • Yes, the XP VMs are getting an IP from the same DHCP server just like Win7/8/10 clients (which do not have an issue joining the Domain). – KidACrimson Jan 5 at 19:08
  • @joeqwerty, nothing found in logs on the DC, at least not yet. I will run BPA for DNS and report back... – KidACrimson Jan 5 at 19:09

This has been resolved now. The DC was incorrectly reporting on the status of SMB1 (showing enabled when in fact it was not yet enabled): enter image description here

Running this PowerShell command fixed the issue (resource link here):
Set-SmbServerConfiguration -EnableSMB1Protocol $true

    Nice Find. My guess is that installing the SMB 1 feature doesn't actually enable it, much like installing the AD DS Role doesn't create a Domain Controller and Domain but just installs the "bits" needed to do so. – joeqwerty Jan 8 at 17:32

Do you have group policy configured to restrict legacy Kerberos encryption types? Some hardening guides or audit policies force you to configure this which could render legacy clients like XP unable to authenticate properly.

The setting is in Windows Settings - Security Settings - Local Policies - Security Options - Network security: Configure encryption types allowed for Kerberos. More info here:

https://docs.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/network-security-configure-encryption-types-allowed-for-kerberos

  • Im not sure, but wasnt there at some point in time you could change/raise the domain compatibliy, so xp clients couldnt be used any more? – Mr Zach Jan 5 at 19:48
  • Thank you, Ryan. This setting is undefined on the DC, so doesn't seem to be the issue. – KidACrimson Jan 6 at 4:41
