Hi there, here is my situation:
My corporate FW is a 3com superstack 3 firewall; it is also our VPN server and hosts all VPN connections to our network. Aside from its standard encryption and authentication, it offers XAUTH authentication. Our clients that are using Windows 2000 machines get a windows login prompt when they try to use the VPN from a remote location, but with the XP machines, we have to disable XAUTH, as no prompt appears and the connection cannot be validated.
When Xauth is off, then the XP machines connect fine. But with our setup we need to be able to offer this extra form of authentication.
Any ideas or opinions would be greatly appreciated.
