The DNS search order is reversed on the DHCP client in Windows 2000 and Windows XP

Article ID: 840629 - View products that this article applies to.

Notice

SYMPTOMS

When you use a dial-up or a virtual private network (VPN) connection to connect to a Routing and Remote Access server, the list of Domain Name System (DNS) servers is stored on the client computer in reverse order.

For example, when you connect to the Routing and Remote Access server, Dynamic Host Configuration Protocol (DHCP) sends the DNS IP addresses in the preferred order:

10.200.200.200
10.201.201.201

However, if you view the TCP/IP protocol properties on the client computer, the DNS IP addresses appear in the following order:

10.201.201.201
10.200.200.200

CAUSE

This problem occurs because the Remote Access Point-to-Point Protocol (PPP) component (Rasppp.dll) writes the DNS IP addresses to the client registry in reverse order.
