Configuring SNMP Agent in Windows NT Systems

For details about installing SNMP agents in Windows systems, refer to
Installing SNMP Agent on Windows Systems
.

To configure SNMP agent in Windows NT systems, follow the steps given below:
Click Start, point to Settings, click Control Panel.
Under Administrative Tools, click Services.
In the details pane, right-click SNMP Service and select Properties.
In the Security tab, select Send authentication trap if you want a trap message to be sent whenever authentication fails.
Under Accepted Community Names, click Add.
In the Community Names box, type the community name to authenticate the SNMP requests.
To move the name to the Accepted Community Names list, click Add.
Repeat steps 6 and 7 for any additional community name.
To specify whether to accept SNMP packets from any host or from only specified hosts, click one of two options:

Accept SNMP Packets From Any Host, if no SNMP packets are to be rejected on the basis of source computer ID.
Only Accept SNMP Packets From These Hosts, if SNMP packets are to be accepted only from the computers listed. To designate specific hosts, click Add, type the names or addresses of the hosts from which you will accept requests in the IP Host or IPX Address box, and then click Add.

Repeat step 11 for any additional hosts.
In the Agent tab, specify the appropriate information (such as comments about the user, location, and services).
Click OK to apply the changes.
Further, the SNMP Agent running Windows NT does not respond to Host Resource Data, by default. To include this support, you should have Windows NT Service Pack 6 & above. Verify this and then follow the steps given below:
Extract the NTHR-MIB.zip available at  
http://bonitas.adventnet.com/opmanager/09Sep2004/NTHR-MIB.zip
into C:WinNTsystem32 folder.
Double click on the registry files to import the mibs into Windows registry.
Restart your Windows NT box.
