SYMPTOMS
When a server tries to initiate Extensible Authentication Protocol (EAP-OE) in order to connect to the local area network (LAN) during startup, the connection may not succeed if the server tries to use a computer's certificate without a user's being logged on.
CAUSE
This behavior can occur because EAP/Transport Layer Security (EAP/TLS) cannot support a computer certificate authentication unless a user is logged on. The Schannel certificate mapper does not support mapping computer certificates to computer accounts.
RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
