Windows 10: Renaming domain-joined machines so DNS = NetBIOS name...

We have three computers that are joined to the domain that need to be renamed due to the fact that the DNS name doesn't match the NetBIOS name (the DNS name is too long and needs a few characters shaved off of it so it can fit in the NetBIOS 15-character limit imposed by Microsoft.

For example, in DNS the machine name is 'RONALDMCDONALD01'. But the NetBIOS name is 'RONALDMCDONALD0' (with the '1' cut off at the end). So, we want to rename the machine so the DNS name matches the NetBIOS name (remove the '1' at the end of the DNS name).

What breaks? What else has to be touched/changed/tested if we do this? Does AD get temperamental? Windows? installed applications like Office? Thx!!

Join a machine to domain with an existing computer name without notification?

As far as i remember from my last job, when you are trying to join a machine to a domain with an existing computer name, you should receive a notification and are not allowed to do that.

In this new company, it seems, when you join a machine to a domain with an existing computer name, you are allowed to do that, And that will destroy the relationship of the other machine and domain.

May i know is there a setting i can change to enable the notification when people trying to join a machine to a domain with an existing computer name?

Thanks!

 

Unable to Join Domain with Win 10 Pro

Config:

Windows SBS 2003 server. Domain Verticon.

New notebook with Win 10 pro.

Connected via in house wifi

Error:

An Active Directory domain controller (AD DC) for the domain 'Verticon' could not be connected.

details:

Note: This information is intended for a network administrator. If you are not your network's administrator, notify the administrator that you received this information, which has been recorded in the file C:\Windows\debug\dcdiag.txt.

The domain name "VERTICON" might be a NetBIOS domain name. If this is the case, verify that the domain name is properly registered with WINS.

If you are certain that the name is not a NetBIOS domain name, then the following information can help you troubleshoot your DNS configuration.

The following error occurred when DNS was queried for the service location (SRV) resource record used to locate an Active Directory Domain Controller (AD DC) for domain "VERTICON":

The error was: "DNS name does not exist."

(error code 0x0000232B RCODE_NAME_ERROR)

The query was for the SRV record for _ldap._tcp.dc._msdcs.VERTICON

Common causes of this error include the following:

- The DNS SRV records required to locate a AD DC for the domain are not registered in DNS. These records are registered with a DNS server automatically when a AD DC is added to a domain. They are updated by the AD DC at set intervals. This computer is configured
to use DNS servers with the following IP addresses:

192.168.1.2

- One or more of the following zones do not include delegation to its child zone:

VERTICON

Windows 10 loses connectivity after joining domain

Hello all,

I'm having an issue joining a new windows 10 workstation to a windows server 2012 dominant domain.

All the IP's are static, an entry is manually entered in our DNS, a computer account is in AD.

I've successfully joined it, but presumed that GPO's broke it due to ping errors resulting in "General Failure." to anything but the localhost.

Removing it from the domain and deleting the policies in regedit seemed to have fixed it, but rejoining it under an OU without GPO's linked or inherited breaks it again.

As soon as it joins, there is no connectivity and results in the previous error, "General Failure."

I've noticed that when we 'successfully(?)' join it to the domain, we get the following error:

Changing the Primary Domain DNS name of this computer to "" failed. The name will remain "<DNS domain>.<top level domain>".

I'm unsure of what's going on. We've tried multiple troubleshooting methods from various websites and forums, all without success.

Anything helps!
