   I am trying to configure an Windows NT4 Server as a VPN client to a vendor's   
   VPN server. My VPN client (the NT4 Server) is running NT4 SP6a with all the   
   patches applied to it. I can connect to the VPN one time, and after I   
   disconnect, I am unable to connect again for a certain period of time. I   
   would say about 15 minutes, but I have nothing to back that number up, other   
   than trial and error. When I try to redial I get an error 678 ("There was no   
   answer"), but the error returns instantly, like it's not even trying to   
   reconnect. I have not yet setup a sniffer to verify this, but I suspect that   
   the OS is not making any attempt to connect since the errors return   
   instantly. When I do a route print after the connection is disconnected, it   
   still shows the route, so I've tried deleting the route, and then attempting   
   to reconnect, but still get the same error. I know this problem is NT   
   specific, because if I connect from any Windows 2000 machine, I have no   
   trouble making back to back connections. I know the problem is not a   
   firewall problem, because my Win2k machines can connect with no problems,   
   and my NT4 Server does connect, even if it does need a "rest" between   
   connections. Does someone know if there is a connection being held open that   
   needs to be reset, such as the PPP adapter which is setup during the PPTP   
   connection? Is there a setting that I have overlooked or some registry value   
   that needs to be tweaked? I have done a lot of searching on this topic and   
   cannot find any possible resolutions, so any suggestions are greatly   
   appreaciated.   
      
   Thanks
