You are an administrator for the Contoso Corporation. Many of your users have laptops that they take when they meet with customers or work from home. The laptops are running Windows 7 and Windows 8. Some laptops are 32-bit machines; others are 64-bit. You have two remote access servers, each located at two different sites. If users cannot connect to one remote access server, they can connect to the other remote access server. Your remote servers support L2TP with IPsec. For IPsec, you assign digital certificates to users with the domain. Because consultants and vendors are not part of the domain, you use a passkey for IPsec instead of digital certificates. How can you simplify the configuring of a VPN connection on each mobile computer?
