Hello, we use a Vodafone UMTS card and we want to connect to the network through Netscreen VPN. We can connect to the network (ping to servers) but when we try to access the sources on the file server we see the error:"password not valid" We cannot access the Exchange server either. In the log files of the firewall and the VPN i can only see the everything is OK, but why the windows authentication failed then? Any help is welcome! Thanks!
