I have two machines connecting to a corporate LAN with a PPTP. Originally both machines worked fine however the main PC has decided to give me Error 800 on connecting to the corporate LAN the other machine which is a Laptop connects fine. Both machines are running XP Pro SP2 and the vpn connection is set up in the same way on both.
Remote machines both running vpn on 10.0.0.0/8 ip range running through a DLink Wireless DSL-G604T router connecting to a Zywall 10w and then to a SBS2003 server.
I am completely out of ideas, the laptop works fine but the workstation does not I have even re-installed the workstation.
