  Functions of NetLogon Service on Domain Controllers: NetLogon Service is very important for Domain Controllers. This service is started and configured to start Automatic when you promote a server to Domain Controller. If this service is not running then there are a few things which fail. 11. This service is responsible for creating a Secure Channel between Domain Controllers and client     computers. Secure Channel is created to pass the authentication packets. 22.   Service performs the registration of SRV records, CNAME and other DC records in the DNS Server to advertise the availability of Domain Controllers in the domain. 33.   SRV Records registered by NetLogon Service are stored in C:\Windows\System32\Config\NetLogon.DNS file. 44.   Performs registration of SRV Records every 24 hours depending on the version of Operating System in use. 55.   Registers the SRV Records for a site where there is no Domain Controller. This is called Site coverage.
