I have a user that is using a PPTP VPN connection to a 2003 Windows Server. &nbsp;He used to be able to connect okay, but now can not. &nbsp;He said it started messing up after a power outage. &nbsp;He has AT&amp;T for DSL using a LinkSys router. &nbsp;I've only connected via the web to look at the settings. &nbsp;The IP of the LinkSys is 192.169.0.1. &nbsp;I connected to that and it looks to be a Speed Stream DSL modem router. &nbsp;The LinSys is using DHCP and then giving out IP addresses of 192.168.1.* &nbsp;I thought maybe the LinkSys was blocking it so we replaced it and are still getting the same results. &nbsp;If I connect an Air Card the VPN will connect okay so the problem seems to be at the users home. &nbsp;Could AT&amp;T be blocking it? &nbsp;I was able to connect to the server via RDP. &nbsp;Oh and I am getting a 619 error.<br />

PPTP VPN 619 Error

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).

Windows Server 2003

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
