Check your secondary-server's shared secret.

I have my first accounting server specified as the primary accounting server, and everything is working fine as is. The problem I'm having is related to my second server, which I intend to use as a backup in case the first one goes down. When my second server is set as the secondary server, everything works okay. However, when I have my second server set as the primary first backup, no accounting records are recorded and the NT event log is full of malformed packets. What is different about the packets when they are sent to the server configured as the primary first backup versus the secondary? My other chassis which runs a NSC has no problem at all with the second server. Thanks for your help. Anu Jolliffe Network Administrator Imagen Communications Inc. (250) 538-0406 FAX (250) 537-5820
