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.

RESOLUTION

    VersionProductMilestoneService branch
    6.0.600 0 . 20 xxx Windows RTM LDR
    6.0.600 1 . 22 xxx Windows Vista SP1 and Windows Server 2008 SP1 SP1 LDR
  • Service Pack 1 is integrated into Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
  • The MANIFEST files (.manifest) and MUM files (.mum) installed for each environment are listed separately. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files (attributes not listed) are signed with a Microsoft digital signature.
