A VPN session works incorrectly during deployment of Windows 7 SP1 or Windows Server 2008 R2 SP1, and deployment fails

Applies to: Windows 7 EnterpriseWindows 7 ProfessionalWindows 7 Ultimate

Symptoms


Consider the following scenario:
  • You have an Active Directory domain environment.
  • You have a Windows 7 Service Pack 1 (SP1) installation image or a Windows Server 2008 R2 Service Pack 1 (SP1) installation image.
  • You try to deploy the installation image to a client computer.
  • A VPN session is established on the computer before the deployment is completed and the computer restarts.
In this scenario, the VPN session may only work intermittently while it communicates with the other domain resources. Therefore, the deployment cannot be completed.

For example, an application may use the VPN session to retrieve remote resources in the domain. In this example, the application crashes when it is retrieving the resources.

Note You may also notice this issue in the following scenario:
  • You open Network Connections under Network and Internet in Control Panel.
  • You double-click the VPN adapter, and the Status dialog box opens to the General tab.
  • You click Details on the General tab.
In this scenario, the dialog box stops responding, and "Not Responding" is added to the title of the dialog box.

Cause


This issue occurs because of a deadlock between DHCP client service and the DNS client service.This in turn prevents DNS queries from fetching the results.

Resolution


To resolve this issue, apply the following hotfix to the Windows 7 Service Pack 1 (SP1) installation image or to the Windows Server 2008 R2 Service Pack 1 (SP1) installation image.
