DsDeregisterDnsHostRecords function

The DsDeregisterDnsHostRecords function deletes DNS entries, except for type A records registered by a domain controller. Only an administrator, account operator, or server operator may call this function.

Syntax

DWORD DsDeregisterDnsHostRecords(
  _In_opt_  LPTSTR ServerName,
  _In_opt_  LPTSTR DnsDomainName,
  _In_opt_  GUID *DomainGuid,
  _In_opt_  GUID *DsaGuid,
  _In_      LPTSTR DnsHostName
);

Parameters

ServerName [in, optional]

The null-terminated string that specifies the name of the remote domain controller. Can be set to NULL if the calling application is running on the domain controller being updated.

DnsDomainName [in, optional]

The null-terminated string that specifies the DNS domain name of the domain occupied by the domain controller. It is unnecessary for this to be a domain hosted by this domain controller. If NULL, the DnsHostName with the leftmost label removed is specified.

DomainGuid [in, optional]

Pointer to the Domain GUID of the domain. If NULL, GUID specific names are not removed.

DsaGuid [in, optional]

Pointer to the GUID of the NTDS-DSA object to be deleted. If NULL, NTDS-DSA specific names are not removed.

DnsHostName [in]

Pointer to the null-terminated string that specifies the DNS host name of the domain controller whose DNS records are being deleted.

Return value

Remarks

This function deregisters SRV and CNAME records only. It leaves type A records intact. Deletion of site specific records, for example, _ldap._tcp._<SiteName>._sites.dc._msdcs.<DnsDomainName>, is attempted for every site (<SiteName> in this example) in the enterprise of the domain controller on which the function is executed. Therefore, this function call could create a time-consuming run and may generate significant network traffic for enterprises with many sites.
