The following sections describe concepts for configuring DNS to work with. Default DNS Permissions for SRV Records. Group in Active Directory.

Mnemonic Type DNS Record Requirements 1. PDC SRV _ldap._tcp.pdc._msdcs. One per domain 2. GC SRV _ldap._tcp.gc._msdcs. At least one per forest 3. KDC SRV _kerberos._tcp.dc._msdcs.

At least one per domain 4. DC SRV _ldap._tcp.dc._msdcs.

At least one per domain 5 A One per domain controller (domain controllers that have multiple IP addresses can have more than one A resource record) 6. GcIpAddress A gc._msdcs. At least one per forest 7. DsaCname CNAME._msdcs.

One per domain controller Below I have mentioned the location of all these important records, with their properties and NSLOOKUP commands to verify if the record exists correctly or not. I have taken screenshot from a single domain lab, on default site i.e. My domain itself represent the forest. So results may vary if you explore these in big infrastructure. In the records Properties window, you will notice below few fields: Priority- The priority of the server.

Clients attempt to contact the server with the lowest priority. Weight - A load-balancing mechanism that is used when selecting a target host from those that have the same priority. Clients randomly choose SRV records that specify target hosts to be contacted, with probability proportional to the weight Port Number- The port where the server is listening for this service. Lexar Usb Format Zip Drive. Target - The fully qualified domain name of the host computer. Host Records for SRV-Aware Clients 1. PDC Record - _ldap._tcp.pdc._msdcs. Allows a client to locate the server that is acting as the primary domain controller (also known as a 'PDC') in the mixed-mode domain named in DnsDomainName.

Only the PDC emulator master of the domain registers this SRV record. GC Record - _ldap._tcp.gc._msdcs. Allows a client to locate a Global Catalog (gc) server for this forest. Only domain controllers that are functioning as Global Catalog servers for the forest named in DnsForestName register this SRV record.
