Module Name:
wsconfig.c
Abstract:
This module contains the Workstation service configuration routines.
Author:
Rita Wong (ritaw) 22-May-1991
Revision History:
08-May-1992 JohnRo
Wksta transports are just an array of values for one key,
not an entire section. Ditto for other domains for the browser.
13-May-1992 JohnRo
Reworked to share code with registry watch code.

Routine Description:
This function determines whether we are a member of a domain, or of
a workgroup. First it checks to make sure we're running on a Windows NT
system (otherwise we're obviously in a domain) and if so, queries LSA
to get the Primary domain SID, if this is NULL, we're in a workgroup.
If we fail for some random unexpected reason, we'll pretend we're in a
domain (it's more restrictive).
Arguments:
None
Return Value:
TRUE - We're in a workgroup
FALSE - We're in a domain

Routine Description:
This function tells the datagram receiver the names to listen on for
datagrams. The names include the computer name, the primary domain,
name and the other domains. The logon domain is not added here; it is
made known to the datagram receiver whenever a user logs on.
Arguments:
None.
Return Value:
NET_API_STATUS - NERR_Success or reason for failure.
Warning:
This routine is UNICODE only.
