SYMPTOMS

You use a dial-up or a virtual private network (VPN) connection to connect to a Routing and Remote Access server. However, the list of Domain Name System (DNS) servers that is stored on the Windows Vista or Windows Server 2008-based Dynamic Host Configuration Protocol (DHCP) client computer is in reverse order.

For example, when you connect to the Routing and Remote Access server, the DHCP server 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
This problem may cause excessive WAN traffic or poor DNS performance.

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.
