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, click the following article number to view the article in the Microsoft Knowledge Base:
