SNMP Issue on an 2620 Router

[DELL ACORD]

In the Sys log. I'm getting a message %SNMP-3-AUTHFAIL: Authentication failure for SNMP req from host x.x.x.x. I have used the Error message Decoder and found out what the message means. But did not give me anymore details. The device in question is an NT File and Print server. There is an application called Backup Exec that all the other server points to this server for back up information. Any suggestions.

This traps gets generated if someone/NMS app polls the device with incorrect SNMP community strings.
