I have found a common problem on most Windows XP machines, where I cannot connect on a Microsoft VPN (error 721) to a Windows 2000 / 2003 server. However, on the same network with the same gateway, I can connect using a Windows 2000 machine. And the REALLY weird thing is, if I firstly connect using the Windows 2000 machine, the Windows XP machine then connects ok. I have found this issue with all versions of XP, with SP1 and 2. Does anyone know of any fixes to help solve this problem?

Thanks a lot,
Daniel Murfitt

From Robert Lin in another forum:
"...check the router settings and make sure TCP Port 1723, IP Protocol 47 (GRE) are opened. Also make sure that the router has the PPTP enabled and not firewall block the traffic."
