SYMPTOMS
When you try to use a Microsoft Windows 2000-based computer to connect to a wireless network, you may receive the following error message:

ERROR: EapType 26 failed in RasEapMakeMessage and returned 0x80004005



CAUSE
This problem may occur if the Windows 2000 client cannot obtain an IP address.

Typically, you receive this error message when you try to connect to a wireless network that is running Internet Authentication Service (IAS) through a switch that is manufactured by Cisco Systems, Inc. When the connection is negotiated by using the Protected Extensible Authentication Protocol (PEAP), the computer does not respond to the seventh Extensible Authentication Protocol (EAP) packet, because the Cisco switch cannot forward the packet.
