I install the snmp server in the windows NT 4.0 thought the network propority windows, after that, I try to use some network utility such as “netstat”,I got the error “Can not locate the entry for snmp in snmpapi.dll, and the interface init fail: 2”
no respond from the command.eventhough I uninstall the snmp server,the result is the same,what should I do?
