SYMPTOMS

Consider the following scenario:
  • You are running a Microsoft Windows XP Service Pack 2 (SP2)-based computer or a Windows XP Service Pack 1 (SP1)-based computer that has the network address translation traversal (NAT-T) update installed.
  • The computer belongs to a domain.
  • You enable an Internet Protocol security (IPsec) policy on the computer.
In this scenario, all policies on the computer are refreshed, not just the IPsec policy. Additionally, if you set a short refresh time for the IPsec policy, network traffic increases in a domain that contains many client computers.

Note The NAT-T update is discussed in the following Microsoft Knowledge Base article:
818043  (http://support.microsoft.com/kb/818043/ ) L2TP/IPsec NAT-T update for Windows XP and Windows 2000
