SYMPTOMS
When a Microsoft Windows 95-based client attempts to connect to a Windows NT-based server using encryption, the client may receive the following error message:

No domain server was available to validate your password. You may not be able to gain access to some network resources.

The following event ID may also appear in the event log:

Event ID: 8006

Description: The browser has received an illegal datagram from the remote computer &quot; &quot; to name &quot; &quot; on transport &quot; &quot;. The data is the datagram.

If the Enable Encryption check box is selected for the Windows 95-based client connection, the problem does not occur.



CAUSE
Under certain circumstances, Windows NT and Windows 95 may lose synchronization when you are using encryption. This causes the client and the server to use different keys.
