Resolve

Correct registry data

Data that is stored in the Windows registry has become corrupted and must be replaced. You must use Registry Editor to correct the indicated registry value.

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

To correct data in the registry:

Caution: Incorrectly editing the registry might severely damage your system. Before making changes to the registry, you should back up any valued data.

  1. On the DNS server, click Start.

  2. In Start Search, type regedit, and then press ENTER.

  3. Expand the following key in the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DNS Server

  4. Browse to the indicated registry entry, right-click the entry, and then, on the Edit menu, click Modify.

  5. Type the correct value, and then click OK.

  6. On the DNS server, start Server Manager. To start Server Manager, click Start, click Administrative Tools, and then click Server Manager.

  7. In the console tree, expand Roles, expand DNS Server, and then expand DNS.

  8. Right-click the DNS server, click All Tasks, and then click Restart.

 

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
