We have a Windows 2000 Server for our office network. We have 10 computers connected, and we store most of our data on this server. My boss needs to connect to this information while on the road using Cox Dial-Up or AOL Dial-Up. The server is behind a LINKSYS BEFVP41 Router and a 3COM 3300 XM Switch. We use a Cox Cable modem for our internet connection, and the Windows XP (Service Pack 1) Laptop can see the network fine as long as it is plugged into the LAN. We use Softremote LT for our VPN, and we have successfully set up a VPN for a Dell Windows 2000 Laptop. But on the XP Laptop, you can ping the Server but cannot see it. The router has the latest firmware, and its not an active directory issue because I have one laptop that can see the network using the VPN. I have disabled the Windows Firewall, but we do have Norton Firewall running.
I checked the log for the router, and I can see the Laptop trying to connect, but then a red line shows up like the following:
IKE ** Check your Encryption and Authentication method settings !
This error message does not show up when I connect the other working laptop to the VPN.
