SYMPTOMS
You run the dcdiag /test:dns command at a command prompt on a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based computer. When you do this, you may receive an error message that is similar to the following:

Error: Forwarders list has invalid forwarder:   Name resolution is not functional. _ldap._tcp.test.com failed on the DNS server

Note In this error message,  is a placeholder for the IP address of the Domain Name System (DNS) server.

<div class="cause_section">

CAUSE
This behavior occurs when all the following conditions are true:
 * You previously configured conditional forwarding on the DNS server.

For example, you previously configured  for the   DNS server and   for all other DNS servers.

Note In this example,  is a placeholder for the DNS server to which you point the   IP address.
 * You run the dcdiag /test:dns command at a command prompt.

Note When you run the dcdiag /test:dns command, it queries all the conditional forwarders for the  DNS server instead of just querying only the   DNS server. The  DNS server does not contain the zone for the   DNS server. Therefore, the DNS server does not reply.
