Clients Cannot Connect to Secure Web Site That Requires Reverse Lookup

Article ID: 255221

Article Last Modified on 11/1/2006



APPLIES TO

  • Microsoft Windows NT Server 4.0 Standard Edition



This article was previously published under Q255221

SYMPTOMS

Network clients may be unable to connect to secure Web sites that verify that the client Internet Protocol (IP) address belongs to a domain name registered in North America. If you attempt to download 128-bit encryption, you may receive a message stating that your IP address cannot be resolved to a domain name registered in North America.

Clients experience no other problems browsing the Internet. Your Domain Naming System (DNS) server has a reverse lookup zone that is correctly configured.

CAUSE

This behavior can occur when your DNS server is not registered with Internic to provide reverse lookup resolution for the network address of a segment of your network. When the DNS server has not registered a segment's network address with Internic, reverse lookup will not succeed for clients that have an IP address belonging to that network segment; the IP address cannot be resolved to a domain name.

RESOLUTION

To resolve this behavior, use reverse lookup resolution for the network segment by registering the network address of the segment with Internic on your DNS server.
