5.1.3.4Guidelines for configuring name resolution

Since WINS is the preferred method of name resolution, it is recommended to use WINS whenever possible. This section contains simple guidelines for configuring static name mappings for a particular Advanced Server computer in situations where WINS servers are not used. In what follows, “PDC” denotes a Primary Domain Controller and “BDC” denotes a Backup Domain Controller.

Within a domain, a PDC must be able to find all BDCs:

Template: BDC nnn.nnn.nnn.nnn UN #0,20

Within a domain, each BDC must be able to find its PDC:

Template: PDC	nnn.nnn.nnn.nnn	UN	#0,20
PDC.DOM	nnn.nnn.nnn.nnn	UN	#1b

(Note that when installing a BDC, the local machine must already be able to find the PDC!)

Before setting up a trust relationsship between two domains, the two PDCs must be able to find each other:

Template: OTHERPDC nnn.nnn.nnn.nnn UN #0,20

OTHERPDC.DOM nnn.nnn.nnn.nnn UN #1b

OTHERPDC.DOM nnn.nnn.nnn.nnn GR #1c

If Windows NT servers are part of your domain – either as PDC or BDC – and WINS is not used, keep in mind that similar rules apply for LMHOSTS files. For more information about the LMHOSTS file, see Windows NT Help and the “Microsoft Windows NT Resource Kit Networking Guide” .

5.1.4 Configuring NetBIOS Tunable Parameters

On Advanced Server for UNIX computers, NetBIOS services are provided by two STREAMS drivers which are linked to the UNIX kernel during NetBIOS installation. Following is a list of tuning variables which are used to control the behavior of NetBIOS (for the default values refer to the /etc/conf/cf.d/mtune file). Note that a NetBIOS upgrade instal- lation may change the default values for a tunable parameter in the mtune file, but does not change local settings in the stune file.

NBMAXNAMES default: 140, min: 40, max: 4096

NBRFCCACHE default: 16, min: 0, max: 4000
