For organizations that want to extend Exchange 2003 to dial-up or VPN users, or to create secured tunnels between sites, the Windows 2003 Routing and Remote Access Service (RRAS) provides secured end-to-end connections. RRAS hasn't changed much between Windows 2000 and Windows 2003, but if administrators used Remote Access Server (RAS) in Windows NT4, they'll find drastic improvements in functions and options in the new RRAS technology.

Routing and Remote Access Service provides a secured remote access solution for mobile users. Although Exchange 2003 provides a greatly enhanced Outlook Web Access (covered in Chapter 26, "Everything You Need to Know About the OWA Client") and secured Outlook 2003 to Exchange 2003 RPC over HTTP (covered in Chapter 25, "Getting the Most out of the Microsoft Outlook Client"), which eliminate the need to create VPN tunnels between client and server, organizations still have client-to-server tunnel requirements.

Many users require some form of dial-up modem access for their email in locations where high-speed Internet is not available. Other users not only want to access Outlook information but also transfer files and access other applications over a VPN tunnel. RRAS provides these mobile user capabilities.

RRAS not only provides client-to-server tunneling, but also provides the ability for an organization to establish tunnels between networks for site-to-site tunneling. Rather than paying for expensive point-to-point lease-line connections or frame-relay lines, an organization can establish a tunnel between multiple sites over the Internet. With lower cost DSL, CableModem, or remote satellite Internet connections, tunnels can secure internal messaging between sites using RRAS.
