Event ID 503 — DNS Server Configuration

  • Article

Applies To: Windows Server 2008

The DNS server configuration consists of the settings that determine how the DNS server will function on a network and how those settings are stored and retrieved when they are needed.

 

Event Details

Product: Windows Operating System
ID: 503
Source: Microsoft-Windows-DNS-Server-Service
Version: 6.0
Symbolic Name: DNS_EVENT_SECONDARY_REQUIRES_MASTERS
Message: The DNS server has detected that the secondary zone %1 has no master IP addresses in registry data. Secondary zones require at least one master server to act as a source. You can add or update the IP address for the master server for this zone using the DNS console. For more information, see "To update the master server for a secondary zone" in the online Help.

Update the master server

A secondary zone must be configured with the IP addresses of one or more master servers that host the primary zone.

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To update the master server for a secondary zone:

  1. On the DNS server, start Server Manager. To start Server Manager, click Start, click Administrative Tools, and then click Server Manager.
  2. In the console tree, expand Roles, expand DNS Server, and then expand DNS.
  3. Expand the DNS server, and then expand the folder containing the applicable secondary zone.
  4. Right-click the secondary zone, and then click Properties.
  5. On the General tab, click Edit.
  6. In the Edit Master Servers dialog box, click the IP addresses of master servers list, type the name or IP address of a master server, and then click the list again.
  7. Click OK to close the dialog box, and then click OK to close <Zone Name> Properties.

Verify

To verify that the Domain Name System (DNS) configuration is correct, verify that all configuration settings are correct, check the event log for events that indicate continuing problems, and then verify that DNS client computers are able to resolve names properly.

To verify DNS configuration settings:

  1. On the DNS server, start Server Manager. To start Server Manager, click Start, click Administrative Tools, and then click Server Manager.
  2. In the console tree, double-click Roles, double-click DNS Server, and then double-click DNS.
  3. Right-click the DNS server, and then click Properties.
  4. Review the settings on each tab, and verify that they contain the intended values.
  5. Expand the DNS server.
  6. Expand a zone folder, right-click a zone, and then click Properties.
  7. Review the settings on each tab, and verify that they contain the intended values.
  8. Repeat steps 6 and 7 for each zone.

To verify that DNS client computers can resolve names properly:

  1. On a DNS client computer, open a command prompt. To open a command prompt, click Start, click Run, type cmd, and then click OK.
  2. At the command prompt, type pinghostname (where hostname is the DNS name of a computer with a known IP address), and then press ENTER.

If the client can resolve the name, the ping command responds with the following message:

Pinginghostname [ip_address]

Note: The name resolution is successful even if the ping command reports that the destination is unreachable.

If the client cannot resolve the name, the ping command responds with the following message:

Ping request could not find hosthostname
