Event ID 403 — DNS Server Service Status

  • Article

Applies To: Windows Server 2008

The DNS Server service responds to requests from DNS client computers for name resolution services. Domain Name System (DNS) is a protocol that enables a computer to obtain the numeric IP address of another computer by submitting the target computer's name to a DNS server. Problems with the DNS Server service can cause network performance to degrade or even prevent network computers from being able to locate each other.
