This topic describes how to configure an IP Security (IPsec) network for Windows® PE Clients. Windows PE supports IPsec protocol by default, but in some cases the computer you want to connect to will not allow a connection. You must configure the security policy to allow the Windows PE client to connect.

By default, Windows PE IPsec policy uses the following security and authentication methods:

  • MM Security Offer: AES128-SHA1-ECP256;

    Where MM is Main Mode.

  • MM Authentication Method: Anonymous

  • QM Policy: 3DES-SHA1; AES128-SHA1

    Where QM is Quick Mode.

  • QM Authentication Method: NTLMv2

To configure an IPsec policy

On the networked computer you are trying to access, configure the following:

  1. Click Start, point to Administrative Tools, and then click Windows Firewall with Advanced Security.

  2. In the left pane, right-click Windows Firewall with Advanced Security and then select Properties.
