I have setup several VPN networks with firewalls and the such. I need to be able to connect to our VPN Server from our Sales staff out in the field using VPN. The connection and authentifcation is no problem with Win98 Service Release 2 and DUN fix.But the problem is with NT Workstation I can’t get this to authenticate. I have Service pack 5 and even 6 and am sure I have 128bit encyption per white paper Q174474. I get error 721, but error messages are misleading at times. Also I can at my homeconnect my NT workstation to my NT Server no problem but to our office server no can do. The VPN picks up but then drops my connection with 721 error PPP is not responding. I know they VPN works we keep a live connection to our other locations. NT Server To NT Server
