'''Routing and Remote Access Service''' ('''RRAS''') is a Microsoft [[API]] and server software makethat makes it possible to create applications to administer the routing and remote access service capabilities of the operating system, to function as a network router, and. developersDevelopers can also use RRAS to implement routing protocols. The RRAS server functionality follows and builds upon the [[Remote Access Service]] (RAS) in Windows NT 4.0.<ref name="RRAS MSDN Library">[http://msdn.microsoft.com/en-us/library/Aa446768 RRAS MSDN Library]</ref> RRAS was introduced with Windows 2000 and offered as a download for Windows NT 4.0.

# Multiprotocol [[Router (computing)|Router]] - The computer running RRAS can route IP, [[IPX]], and [[AppleTalk]] simultaneously. All routable protocols are configured from the same administrative utility. RRAS included two unicast routing protocols, [[Routing Information Protocol]] (RIP) and [[Open Shortest Path First]] (OSPF) as well as [[Internet Group Management Protocol|IGMP]] routing and forwarding features for [[IP multicast]]ing.

# [[Dial-on-demand routing|Demand-Dial Router]] - IP and IPX can be routed over on-demand or persistent [[Wide area network|WAN]] links such as analog phone lines or [[ISDN]], or over [[VPN]] connections.

# [[Remote Access Server]] - provides remote access connectivity to dial-up or VPN remote access clients that use IP, IPX, AppleTalk, or [[NetBEUI]].

Routing services and remote access services used to work separately. [[Point-to-Point Protocol]] (PPP), the protocol suite commonly used to negotiate point-to-point connections, has allowed them to be combined.
