SYMPTOMS

On a network, you deploy a Network Access Protection (NAP) architecture. When you connect to this network from a Windows Vista-based client computer, you can access the network resource correctly. However, after you run the gpupdate /force command to reapply the Group Policy settings, the client computer may lose network connectivity.

This issue occurs when the following conditions are true:
  • Both IPsec policy and connection security rules are configured for NAP architecture.
  • The value of the IKEFlags registry entry is set to 1C in hexadecimal.
    Note This registry entry is located under the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent\Oakley\
