Hi, 
&nbsp; &nbsp; I am trying to establish a VPN connection using RAS API.The sample 
code which comes with Microsoft Platform SDK for windows XP(RasDial.c) 
works fine when run it as an exe.I converted this code to a Windows 
Service.I am running this windows service under an Administrative user 
account(and not the normal localsystem account).When I start the 
service after the user logs in,it works fine and the VPN connection is 
established.However when the same service starts automatically,on 
system restart,it fails with error code 619(ERROR_PORT_DISCONNECTED).Does it have anything to do 
with user login or network library initialization?What else should I initialize? 
 
 
&nbsp; Anyways my requirement is that the VPN connection needs to be 
established before the user logs in.I have a customized login process(by writing my own Custom GINA dll) where the user info is to be sent to a server on user logon.To access the server VPN connection is to be up. Is there any other way in which i can achieve the same. 
 
 
Regards

RASDial and VPN Connection.Error 619 when used in windows service

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
