I am tryping to set up a PPTP tunnel between 2 XP Pro hosts on the same
subnet (192.168.1.0). I have 3 different computers and the problem is the
same regardless of which ones act a clients and which ones act as servers
(i.e. they are set up to receive incoming connections). The client starts to
connect and then gives error 651 (I have read other posts on this but have
not seen any solutions). I put a protocol analyzer on the link (wireshark)
and I see the client starting the TCP handshake to port 1723 with SYN. The
server host responds with a SYN ACK and then the client sends the PPTP
start-control connection request message. At this point the server seems to
hang. It does not acknowledge receipt of the PPTP message and sends another
SYN ACK as if it only received the opening SYN. The client resends the PPTP
message and the server again sends a SYN ACK. This continues until the
client times out and gives the 651 error message. I have a decode file which
I will be happy to send if it helps but this one has me stumped. As I said I
have tried this with various combinations of clients and servers and the
result is always the same. Any help would be appreciated.
