AddTestedDomain
|
|
Add a domain to the list of domains to test.
|
|
|
|
Arguments:
|
|
|
|
pswzNetbiosDomainName - Name of the domain.
|
|
If pswzDnsDomainName is NULL, this can be either a netbios or dns domain name.
|
|
If pswzDnsDomainName is not NULL, this must be the netbios name of the domain.
|
|
|
|
pwszDnsDomainName - Another name of the domain.
|
|
If specified, this must be the DNS name of the domain.
|
|
|
|
|
|
PrimaryDomain - True if this is the primary domain
|
|
|
|
Return Value:
|
|
|
|
Returns pointer to structure describing the domain
|
|
NULL: Memory allocation failure.
