DC Locator DNS records not registered by the DCs

Determines which Domain Controller (DC) Locator DNS records are not registered by the Netlogon service.

To enable this setting, select Enable and specify a list of space-delimited mnemonics (instructions) for the DC Locator DNS records that will not be registered by the DCs to which this setting is applied.

Select the mnemonics from the following list:

Mnemonic Type DNS Record

LdapIpAddress A
Ldap SRV _ldap._tcp.
LdapAtSite SRV _ldap._tcp.._sites.
Pdc SRV _ldap._tcp.pdc._msdcs.
Gc SRV _ldap._tcp.gc._msdcs.
GcAtSite SRV _ldap._tcp.._sites.gc._msdcs.
DcByGuid SRV _ldap._tcp..domains._msdcs.
GcIpAddress A _gc._msdcs.
DsaCname CNAME ._msdcs.
Kdc SRV _kerberos._tcp.dc._msdcs.
KdcAtSite SRV _kerberos._tcp.dc._msdcs.._sites.
Dc SRV _ldap._tcp.dc._msdcs.
DcAtSite SRV _ldap._tcp.._sites.dc._msdcs.
Rfc1510Kdc SRV _kerberos._tcp.
Rfc1510KdcAtSite SRV _kerberos._tcp.._sites.
GenericGc SRV _gc._tcp.

Rfc1510UdpKdc SRV _kerberos._udp.
Rfc1510Kpwd SRV _kpasswd._tcp.
Rfc1510UdpKpwd SRV _kpasswd._udp.

If this setting is disabled, DCs configured to perform dynamic registration of DC Locator DNS records register all DC locator DNS resource records.

If this setting is not applied to DCs, DCs use their local configuration.
