I was (perhaps mistakenly?) merely referencing Microsoft's own
documentation.

WINS
Although Exchange and Windows 2000 prefer DNS for name resolution, most
networks continue to have clients that require NetBIOS; this includes
Outlook 2000 and earlier clients, as well as Exchange 5.5. Do not remove
WINS unless you are positive that there is no need for it anywhere on the
network. Use Performance Monitor to verify the number of WINS requests on
the WINS server to see if any applications are still using it.

Note Outlook can be configured to use DNS only, but this is not the default
client behavior. If your organization decides that the maintenance of WINS
is too costly, you can use a script that modifies select registry entries to
reconfigure the Outlook clients. Also, be aware that there may be other
applications in your network that require NetBIOS name resolution. A
thorough inventory of the network is required before removing WINS.

Best Practice Keep a WINS infrastructure active until you have upgraded all
applications to take advantage of Windows 2000 DNS.
