0x000032cd – Error_Ipsec_Mm_Policy_In_Use – the Specified Main Mode Policy Is Being Used

The "Error_Ipsec_Mm_Policy_In_Use" means that a certain security rule is being used right now, so you can't change or delete it.

This can happen if two connections are using the same rule or if someone is trying to change something while it's still active. You might notice issues like losing a VPN connection or being unable to connect to the internet.

To fix this, find out which rule is active and see if it's really needed. It's important to understand this error for keeping your VPN safe and to help manage rules better in the future.

Error meaning:

The "Error_Ipsec_Mm_Policy_In_Use" means a security rule is already being used for a connection.

This stops you from changing or removing it until it's not in use anymore. It's important to manage these rules carefully.

Causes:

Potential reasons for the "Error_Ipsec_Mm_Policy_In_Use" are:

1. An IPsec Main Mode policy is already active and being used by a connection.
2. There are multiple connections with similar settings that confuse the system.
3. Someone is trying to change or delete a policy that is currently in use.
4. The system prevents conflicting policies from being applied to keep everything secure.

Symptoms:

Symptoms of "Error_Ipsec_Mm_Policy_In_Use":

1. Intermittent or complete loss of VPN connection.
2. Secure communication between devices is blocked.
3. Warning messages in event logs about the Main Mode policy being in use.
4. New VPN connections may fail to establish.
5. Error notifications about policy conflicts appear.
6. Increased latency (slower response times).
7. Packet loss (missing data during transmission).
8. Difficulty accessing network resources.
9. Reduced application performance.
10. Hindered productivity and disrupted business operations.

Solutions:

Step 1: Identify the Main Mode policy that is currently in use for your VPN.

Step 2: Check if this policy is necessary for your VPN setup.

Step 3: If the policy is not needed, disable it using the management console or command-line interface.

Step 4: If the policy is needed, look at its settings and change any parts that might be causing problems.

Step 5: Make sure all devices connected to the VPN have the same configuration to avoid issues.

Step 6: Regularly check and update your IPsec policies to stop this error from happening again.

Step 7: Restart the VPN service to apply all changes and reconnect.

Impact:

The active Main Mode policy controls how VPN connections are safely created.

If this policy is active, it can prevent changes to the VPN settings.

Not being able to update settings can leave the system vulnerable to attacks. Old policies might not meet today's security needs, which can be a problem.

The system can struggle to defend against new threats.

Overall, this can make the VPN less secure and slower to respond to issues.

Organizations need to manage these policies carefully to keep their VPN safe and working well.
