By default, a Windows NT PDC for a domain is also the domain master browser for that domain. A Samba server must be set up as a domain master server in this type of situation. Network browsing may fail if the Samba server is running WINS along with other domain controllers in operation.
For subnets that do not include the Windows NT PDC, a Samba server can be implemented as a local master browser. Configuring the
smb.conf for a local master browser (or no browsing at all) in a domain controller environment is the same as workgroup configuration.
