Does EnterNet 500s PPTP (VPN) shut down better than Microsofts PPTP (VPN)?
Yes. The trouble is that Microsoft PPTP sometimes does not properly release the TCP connection with a TCP Reset. Sometimes a connection cannot be reestablished for several hours or even days (the 629 error). EnterNet 500 issues a TermReq, the server responds with a TermAck, the server then terminates the TCP circuit with a Final bit, the client responds with the TCP reset bit. The server then knows that the TCP connection is free and available for incoming connections. All of this adds up to quick, dependable disconnects from your VPN server.
