3.3 Domain Controller Details
This section specifies how a DFS server on a DC processes and responds to DFS referral requests from DFS clients. It is applicable only to DFS servers running on DCs.<31>
A DFS server on a DC MUST respond to domain, DC, sysvol, root, and link-referral requests.
If that DFS server is also hosting DFS root targets, then in addition to the requirements in this section, it MUST also conform to the requirements in section 3.2 while processing referral requests for those DFS root targets.
