Check the below:

1. Configuration Overwritten by Policies

• If your system is part of a domain, Group Policy settings might be overriding your local configuration. Check with your IT administrator to ensure no policies are resetting the SNMP settings.

2. SNMP Service Restart

• Restarting the SNMP service or the system might reset the configuration. Ensure that the changes are saved properly before restarting.
• To check:
1. Open Services (services.msc).
2. Locate SNMP Service.
3. Right-click and select Properties.
4. Ensure the settings are saved and the service is running.

3. Conflicting Applications or Tools

• Some monitoring tools or third-party applications might modify SNMP settings automatically. Check if any such tools are installed and review their configurations.

4. Permissions Issue

• Ensure you have the necessary administrative privileges to make changes to SNMP settings. Without proper permissions, changes might not persist.

5. SNMP Version Mismatch

• If you're using SNMPv3, ensure that the authentication credentials (username, password, etc.) are correctly configured. A mismatch in credentials could cause the settings to revert.

6. Corrupted Configuration

• If the SNMP configuration file is corrupted, it might not retain changes. Try resetting the SNMP service and reconfiguring it:
1. Stop the SNMP service.
2. Delete or back up the configuration file.
3. Restart the service and reapply the settings.

7. Firewall or Security Software

• Some firewall or security software might block or reset SNMP settings. Check the logs of your security software to see if it's interfering.
