Resolution

This issue may occur if there is a problem with the DefaultGateway and DefaultGatewayMetric registry keys.

Microsoft has identified this issue and has released a hotfix. For more information and to download the hotfix, see Microsoft Knowledge Base article 973243.

To work around this issue:

Note: This procedure modifies the Windows registry. Before making any registry modifications, ensure that you have a current and valid backup of the registry and the virtual machine.
 

1. From the Windows Registry Editor, navigate to:
   
   HKLM/System/CurrentControlSet/Services/Tcpip/Parameters/Interfaces/%CLSID%
    
2. Check the DefaultGateway and DefaultGatewayMetric keys for issues. For example:
    
   • Remove any line feeds before the correct default gateway IP.
   • If the address is missing, add it manually.
