Routine Description:
Returns the name of the domain or workgroup this machine belongs to.
Arguments:
DomainNamePtr - The name of the domain or workgroup
Free the returned buffer user NetApiBufferFree.
DnsDomainNamePtr - Returns the DNS name of the domain this machine is
a member of. NULL is returned if the machine is not a member of
a domain or if that domain has no DNS name.
Free the returned buffer user NetApiBufferFree.
DnsForestNamePtr - Returns the DNS forest name of the forest this
machine is in. NULL is returned if the machine is not a member of
a domain or if that domain has no DNS name.
Free the returned buffer user NetApiBufferFree.
DomainGuidPtr - Returns the domain GUID of the domain this machine is
a member of. NULL is return if the machine is not a member of
a domain or if that domain has no domain GUID.
Free the returned buffer user NetApiBufferFree.
IsWorkgroupName - Returns TRUE if the name is a workgroup name.
Returns FALSE if the name is a domain name.
Return Value:
NERR_Success - Success.
NERR_CfgCompNotFound - There was an error determining the domain name
