SYMPTOMS

Consider the following scenario:
  • You configure multiple addresses for a network adapter on a computer that is running Windows Server 2008 R2 or Windows 7.
  • You change IP address information about the network adapter. The changed IP address is not the first bound address. For example, you add a new IP address to the adapter, you remove an IP address, or you change the IP address configuration.

    Note This operation should trigger the operating system to send route change notifications.
  • You run an application or a service that registers to receive route change notifications on the computer.
In this scenario, the application or service cannot update the routing table after the route change notification is received.

Note The routing table is maintained by the application or the service. It is not the system routing table.

Here is a sample scenario:
  • You install Routing and Remote Access Service (RRAS) on a computer that is running Windows Server 2008 R2. This service registers to receive route change notifications.
  • You add a second IP address to a network adapter on the computer.
  • You open the Routing and Remote Access window, right-click the network adapter, and then select Show IP Routing Table.
In this scenario, the displayed routing table does not show the newly added IP address. The expected behavior is that the RRAS updates the routing table after the service receives route change notifications.

CAUSE

This issue occurs because the "next-hop" address information in the route change notification is incorrect.

Windows 7 and Windows Server 2008 R2 file information notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or to both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    6.1.760 1.21xxxWindows 7 and Windows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, very important issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 R2 and for Windows 7" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
