HELP SQLServer will start, SQL Agent won't

We just had a security fix applied to the server.
When we restarted both SQL Server and SQL Server agent
started. However shortly after, the SQLServerAgent stopped
running. They are both using the same account, but when
you try and start up the SQL Server Agent you get the
following error messages...
[165] ODBC Error: 0, Cannot generate SSPI context
[SQLSTATE HY000]
[000] Unable to connect to server '(local)';
SQLServerAgent cannot start
I have read the KB#811889, but was looking for anyone who
has experienced this issue.
Thanks
