Consider the following scenario:
- On a Windows XP-based client computer, you enable the Wireless Zero Configuration service.
- You try to establish a wireless connection by using Extensible Authentication Protocol (EAP) authentication.However, the connection attempt is unsuccessful.

- This problem occurs if the access point announces a Service Set Identifier (SSID) that includes a comma.

- This problem does not occur if the comma is replaced by another character, such as an underscore character.
