Description:
 Microsoft Exchange Server has detected that Basic Authentication is being attempted between this server and server 'EXCHSRV'.  This authentication mechanism  is not secure and it is not supported between front-ends and back-ends.  If this condition persists, please verify that server 'EXCHSRV' is properly  configured to use Integrated Windows Authentication for each virtual directory  used by Exchange.  After applying any changes it may be necessary to restart Internet Information  Services on both the front-end and back-end servers.

Hi,

here is what I have on the subject:

Mihai Andrei (Last update 10/31/2005):
As per Microsoft: "The text of this message implies that both the front-end server and the back-end server must be configured to use Integrated Windows authentication. This is incorrect. Only the back-end Exchange 2003 server must be configured to use Integrated Windows authentication". See MSEX2K3DB for additional information about this event.

Joerg R. (Last update 7/5/2004):
Microsoft PSS told us to ignore this event.

Ionut Marin (Last update 1/10/2004):
As per Microsoft: "You receive this error event if you configure the back-end Exchange 2003 server virtual roots to use only the Basic authentication authentication method. However, the text in this event description indicates that you must configure both the front-end server and the back-end server to use the Integrated Windows Authentication authentication method. This information is incorrect". See M832397 for the correct description and additional information.  

and here are the links from the article above:
