Enabling SNMP in Windows 2008

First of all you may need to add the “feature” from Server Manager

Now go to Services (in Administrative Tools)

Right click the SNMP Service and select properties . Go to the Security tab

Edit the settings to your needs. In this case I have allowed the host access to this host and kept the Community name as the default public with Read-Only rights.

You can then query this host by whatever means necessary. I am using Cacti to graph  the traffic of the a NIC.
