Mai Anh Tuan: What is the exact failure notice? Some quick thoughts! If the ISA is in Workgroup mode - you'll have to configure the RADIUS settings. Otherwise check the User Account Dial-In properties and the Remote Access Policies. Also - if you did configure the RADIUS - you should have a RADIUS policy as well. Joseph F.
