I am getting a message in event viewer on my second exchange 2k machine in my
domain every ten minutes or so. It is just a information message that states
smtp authentication was performed successfully with server.domain.com using
gssapi$. This message is coming up on the old exchange server's event viewer,
is this something that I need to be concerned about ?
