Cannot find primary DNS server

Title: Cannot find primary DNS server


The NetDiag DNS test is failed with error "Cannot find a primary authoritative DNS server".

This can be caused if the DNS is not configured correctly on the server.

To verify your domain controller's DNS client settings, type the following command at a command prompt to view the details of your Internet Protocol (IP) configuration: ipconfig /all

User Action :

To modify the domain controller's DNS client configuration, follow these steps:

1.    Right-click My Network Places, and then click Properties.
2.    Right-click Local Area Connection, and then click Properties.
3.    Click Internet Protocol (TCP/IP), and then click Properties.
4.    Click Advanced, and then click the DNS tab. To configure the DNS information, follow these steps:

 a. In the DNS server addresses, in order of use box, add the recommended DNS server addresses.
 b.If the For resolution of unqualified names setting is set to Append these DNS suffixes.
Microsoft recommends that you list the Active Directory DNS domain name first
 c. Verify that the DNS Suffix for this connection setting is the same as the Active Directory domain name.
d.  Verify that the Register this connection's addresses in DNS check box is selected.
e.  Click OK three times, If you change any DNS client settings, you must clear the DNS resolver cache and register the DNS resource records. To clear the DNS resolver cache, type the following command at a command prompt: ipconfig /flushdns

To register the DNS resource records, type the following command at a command prompt: ipconfig /registerdns

To confirm that the DNS records are correct in the DNS database, start the DNS management console. There should be a host record for the computer name. (This host record is an "A" record in Advanced view.) There also should be a Start of Authority (SOA) record and a Name Server (NS) record that points to the domain controller.
