SNMP hits to the router

Hi,

I'm informed that there are lot of broadcast packets sent from an windows
2000 server which is one of the domain controller.
It is also the print and file server for this domain.
This is the report which I'm given from the Networking group.
"Jan 12 10:05:41 152.20.80.222* 78640: 19w3d: %SNMP-3-AUTHFAIL:
Authentication failure for SNMP req from host 152.20.80.237**"

Please can any help me in resolving this issue as no snmp services are
enabled in this server and dont know why there are SNMP broadcast from this
server ?

Regards
San
