FQDN on logon screen, why?

[dcjg7085]

Dear all,

I've recently set up 2 windows servers, running server 2008 R2 at the Forrest Functional level server 2008 R2. At the login screen after your press CTRL ALT DEL it used to give the format:

**OurDomainName\Administrator

e.g. mydomain\Administrator

However now it's for some reason giving the format:

**OurFullyQualifiedDomainName\Administrator

e.g. mydomain.internal\Administrator

I don't understand why its started adding the .internal on the end on the logon screen. The servers were configured to have the name: nameofserver.mydoaminname.internal

Being relatively new to windows server 2008, any help or advice would be greatly appreciated as to why this has suddenly changed.

Many Thanks.
