To disable SNMPv1 and activate SNMPv2c on Windows Server, you can follow these steps:

  1. Open "Server Manager":
    Log in to your Windows Server and open "Server Manager" from the taskbar or Start menu.

  2. Install SNMP Feature:
    If SNMP is not already installed, you need to install it as a Windows feature. In Server Manager, click on "Add roles and features." Follow the wizard to install the SNMP feature.

  3. Configure SNMP:
    After installing the SNMP feature, open the "Services" window by pressing Windows Key + R, then type services.msc and hit Enter.

  4. Locate and Stop SNMP Service:
    In the "Services" window, scroll down to find the "SNMP Service" entry. Right-click on it and select "Stop" to stop the SNMP service.

  5. Open SNMP Properties:
    Press Windows Key + R, then type services.msc and hit Enter. In the "Services" window, scroll down to find the "SNMP Service" entry. Right-click on it and select "Properties."

  6. Configure SNMP Service Properties:
    In the SNMP Service properties window, go to the "Security" tab.

  7. Remove SNMPv1:
    In the "Accepted community names" section, remove any community strings associated with SNMPv1. Remove the "public" and "private" community names if they exist. You can select the community name and click "Remove."

  8. Add SNMPv2c Community:
    In the "Accepted community names" section, click "Add." Enter your desired SNMPv2c community string (e.g., "mycommunity") and set the "Accepted SNMP packets from these hosts" to include the specific IP addresses or IP ranges from which you want to allow SNMPv2c access. Click "Add" and then "OK."

  9. Start SNMP Service:
    Go back to the "Services" window, right-click on the "SNMP Service" entry, and select "Start" to start the SNMP service with the new configuration.

  10. Verify SNMP Configuration:
    You can verify that SNMPv1 is disabled and SNMPv2c is enabled by using a network monitoring tool like SNMPwalk or a SNMP manager to query the SNMP agent on the Windows Server.

That's it! You have now disabled SNMPv1 and activated SNMPv2c on your Windows Server. Remember to review and adjust the SNMP community strings and access permissions as needed based on your security requirements.
