Reverse Lookups with BIND Earlier Than 4.8.3 Fail with Unknown Host Error Message

• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server, Enterprise Edition version 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

If an application uses a version of BIND earlier than version 4.8.3 to do a reverse lookup to identify a client, it may receive the following error message:

Unknown Host

CAUSE

Microsoft Domain Name System (DNS) servers do not have an equivalent to a BIND directive called fake-iquery. If old BIND clients use Microsoft DNS servers, the NSLOOKUP fails.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:
