Subject: Ordering of domain in case of DFS domain referral

Hello dochelp team,

I've got a small question regarding the ordering of domain when answering a Domain referral request as described here: Receiving a Domain Referral Request

My questions are:

* in which order the domain should be returned ? if any  (ie. first lower domain like samba.corp then au.samba.corp then brisbane.au.samba.corp)
* I understand that nebios/dns name must go in couple, (ie. not return first all the dns name then all the netios name, but each pair accordingly), but what must appear first NETBIOS domain or DNS domain name ?

Also depending on the answer you'll make on the first point this statement might need also amendment:
"MUST give preference to the NetBIOS and fully qualified names of the DC's own domain first, and then give preference to other domains. This ensures that a client in the same domain as the server will always be able to access SYSVOL and NETLOGON paths correctly.<35>"

As I understand it didn't state that the own domain of the DC must be first, just that if the DC has a choice to make between its own domain referral information and another domain then it should choose its own first. Am I right ?
