  2. Router does not update its ARP table after an IP address fails over to a cluster node in Windows Server 2008 R2

Router does not update its ARP table after an IP address fails over to a cluster node in Windows Server 2008 R2

View products that this article applies to.

Symptoms

Assume that you configure a Windows Server 2008 R2-based failover cluster. An IP address fails over from one cluster node to another cluster node. In this situation, router does not update its Address Resolution Protocol (ARP) table. Therefore, remote client computers cannot reach the cluster node that has the IP address.

Cause

This issue occurs because Windows does not send a gratuitous ARP packet when a new IP address is assigned on the computer.

File information
The global version of this hotfix installs files that have the attributes that are listed in the following tables. The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.
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 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:
    VersionProductMilestoneService branch
    6.1.760
    1.17xxx    		Windows Server 2008 R2SP1GDR
    6.1.760
    1.22xxx    		Windows Server 2008 R2SP1LDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical 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" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
