Unable to Download 128-Bit Encryption Software from Microsoft

ID: Q230064

The information in this article applies to:

SYMPTOMS

When you try to download software from Microsoft that includes 128-bit encryption, you may receive the following error message:

Your computer does not have a Domain Name Service registered for it. We are unable to determine the physical location of your computer. You should contact your system administrator to find out why a DNS entry is not registered for your IP address. A DNS entry is a requirement for downloads at this time.


CAUSE

This issue can occur if the domain name server (DNS) that is the "Start of Authority" for your reverse lookup zone does not have a PTR record for your computer. Because 128-bit encryption technology cannot be exported outside the United States or Canada, Microsoft performs an inverse lookup of your Internet Protocol (IP) address. If Microsoft is unable to resolve this address to a domain name within the United States or Canada, this error message is generated.


RESOLUTION

To resolve this issue, contact your Internet service provider (ISP) to have them create a PTR record for you in the appropriate reverse lookup zone, or have your ISP grant you "Start of Authority" for the IP address range you use so that you can create and maintain a reverse lookup zone.
