APPLIES TO

SYMPTOMS
When you configure a Microsoft Windows XP-based computer to use IEEE 802.1X authentication to connect to a network, the authentication fails.
CAUSE
This problem occurs when the computer name contains a double-byte character or a hyphen (-). 802.1X uses the Extensible Authentication Protocol (EAP) for message exchange during the authentication process. The Windows implementation of the Extensible Authentication Protocol (EAP) does not support these characters.
WORKAROUND
To work around this problem, change the name of the computer to use single-byte characters without hyphens.
- Click Start, right-click My Computer, and then click Properties.
- On the Computer Name tab, click Change.
- Rename the computer, and then click OK two times.
- Restart the computer.
