We are running Microsoft SBS 2003. Service Pack 1. Netcomm NB5 Plus 4 ADSL Modem router. Trend CSM Email, Internet, RWW to our server and to other SBS networks all work fine. I need to be able to VPN to external computers. I can successfully VPN from our SBS server to other external networks but when attempting to create a VPN from any of our SBS workstations, the VPN fails with Error 800. I have enabled and disabled the firewall client on the workstations but this has no impact. Have rerun the internet connection wizard, rerun the VPN wizard on the workstations, checked port forwarding on the router. Port 1723 can be seen via canyouseeme when accessed from the workstation. The user has administrative rights on the network and the workstation. I can connect to the exchange server of the network that I am trying to establish a VPN - via OWA (from our server and our workstations). I cannot ping (from the workstation on our network) the IP of the VPN that I am trying to establish but I can ping the same IP from our server. Any suggestions as to what is causing the lack of VPN communication from the workstations on our network? Wth thank in advance.
