Article ID: 254231 - Last Review: March 1, 2007 - Revision: 5.4 Change in Remote Access route behavior in Windows 2000, in Windows Server 2003, and in Windows XPThis article was previously published under Q254231 SUMMARY
The default behavior of the remote access client in clients that are running Windows 2000, Microsoft Windows XP, or Microsoft Windows Server 2003, is different from earlier versions of Windows. Earlier versions of Windows add a default subnet route to the remote access client when they connect to a remote access server. This route is "classful," meaning that it assumes a network mask based on the address received. MORE INFORMATION
This route table example is from a Microsoft Windows 98 Dial-Up Networking client:

Windows 2000, Windows XP, and Windows Server 2003 do not create the subnet route. The routes added to the client after connecting by using remote access are: a HOST route to the address of the remote access server, a HOST route to the address received, and a default gateway route. The next two sample route tables are from a Windows 2000-based remote access client:

In all of the examples in this article, the remote access server address pool begins at 123.15.0.129. The first address from the pool is used by the remote access server itself. | Article Translations
