Enter the room and building where the device is located e.g. 244 Computing Center for Set Location
Select the Security tab
Enter 18.104.22.168, 22.214.171.124, 126.96.36.199., 188.8.131.52 (these are the IPs of NCS's Network Monitoring Service (NMS) servers) for Accept SNMP Packets from these Hosts.
By default, Windows configures the community name public with READ ONLY rights. Leave public as your only community name. Since you just restricted SNMP queries to the NCS NMS servers, security will be sufficient.
If the monitored device is running a firewall (as it should!), permit SNMP monitoring through the firewall
Start > Control Panel > Windows Firewall.
Select the Exceptions tab
Select Add Program...
Browse to C:\WINDOWS\system32\snmp.exe, clicik Open.
