Cannot generate SSPI context

Hello to all, thanks for any assistance...
This problem just started with in the last day. Accessing a SQL Server from
Enterprise Manager(EM) on my note book. However when I access via EM on the
local sql server, windows authentication works fine...
A connection could not be established to SERVERNAME
Reason: SQL Network Interfaces: The target principle name is incorrect
Cannot generate SSPI context
Also the following appears in the server log
Login failed for user '(null)'. Reason: Not associated with a trusted SQL
Server connection.
From same EM, I can access using SA/password and connect fine.
The server is mixed mode. Thanks for any directions...
