APPLIES TO

  • Microsoft Windows 2000 Server
  • Microsoft Windows 2000 Professional Edition
  • Microsoft Windows 2000 Advanced Server




SYMPTOMS

When you try to resolve a host name address by using the Domain Name System (DNS) fully qualified domain name (FQDN), the Microsoft Windows 2000 Server-based DNS server may take as long as 15 seconds to send a "Server Failure" response to the DNS client computer.

CAUSE

This problem occurs when all the following conditions are true:

  • A client submits a DNS name query to the Windows 2000 DNS server for a host that cannot be resolved.
  • The Windows 2000 DNS server is configured to use either forwarder servers or root hint servers.
  • The Windows 2000 DNS server forwards the DNS name query to another DNS server that is either a forwarder server or a root hint server.

When the Windows 2000 DNS server must forward a name resolution request to another DNS server, and the Windows 2000 DNS server receives a "Server Failure" response from that server, the Windows 2000 DNS server ignores the response and does not immediately return the response to the client. The Windows 2000 DNS server repeats the client query for each forwarder server or root hint server that is configured. After the recursion timeout expires, the Windows 2000 DNS server returns a "Server Failure" response to the client. By default, the recursion timeout expires after15 seconds.
