WINS is an atifact of NetBIOS over TCP/IP.

In the absence of NetBIOS over TCP/IP the Windows 200x/XP client can use
only DNS to lookup names (ie: to find servers as well as essential
services that they provide). That is why the DNS server you use must
include all the special entries that are shown in chapter 10.3.2. Of
course, only those that are applicable should be added to the DNS

ie: To find a DC the Windows 200x/XP client will need to resolve the
following records:


I am not sure how well this would work in the absence of Active Directory
and the AD DNS entries.

In any case, for server configurations without NetBIOS over TCP/IP
understand that the name resolution mechanism relies on DNS.
