WIndows FQDN conflict with Linux FQDN

I am running a Windows 2008 R2 on a WIndows VMWare VM

I am trying to install Active Directory on that VM

From a separate Linux machine, I run the following command:

    # host

Open in new window

From the Windows VM, I run the following command in the powershell

    PS C:\t> (gwmi WIN32_ComputerSystem).Name + "." + (gwmi WIN32_ComputerSystem).Domain

Open in new window

So both Linux and agree on the short single name (field), but they disagree on the FQDN

How can I change the Windows VM to have the FQDN that Linux thinks is the correct FQND

Open in new window

(Note: When I try to install AD with the Linux version of the FQDN, it says there is a conflict)

The FQDN of a Windows machine is determined by the AD Domain.

If you want to add it to an existing domain, it will take FQDN of computer_name plus domain_name.extension, which is in your example.

If you need to create a new Windows domain to much the information returned by your Linux host, the domain must be

Linux host command performs a simple DNS lookup and returns what it finds in its DNS server. It does not query the Windows host.

I agree with Svet Paperov. The answer to your commands depends only of your DNS server.
But AD controller will be its own DNS server (maybe with a alternate dns server), while maybe your Linux has another DNS server that does not know your Windows VM.

To answer your main question I would say you must modify your DNS entry for your Windows VM in the Linux DNS server.
