Winodws and FQDN

Posted on 2014-09-02

On Windows 2008 R2, If I perform the following from Powershell,  I get the following FQDN:

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

Open in new window

At this point I have added a role of ADDS, but I have not yet run the install (dcpromo.exe)

If I need to for any reason, how do I change the FQDN of the Windows machine?

    Until you create a forest with the first Domain Controller you won't have a FQDN, as FQDN stands for Fully Qualified Domain Name. You don't yet have a Forest or Domain, so you can't have a FQDN. Your FQDN will be To change it, you need to either change the server name, the domain it is a member of - or both.
