    • Examine whether or not the dial-up entry has been configured appropriately.

  • If solely manually dialing out to the Web works, and never automated dialing out:

    • Examine whether or not the problematic shopper pc is a SecureNAT shopper. If it’s a SecureNAT shopper, then it’s a must to set up and allow Firewall Shopper software program on the shopper pc

    • Examine whether or not the ISA Server pc has the required permission to make use of the dial-up connection.

    • Examine the configuration of the dial-up entry credentials.

  • If the dial-up connection is abruptly dropped:

When troubleshooting shopper entry authentication issues, contemplate the next essential elements:
