Updated: Feb 21, 2026
Technical Meaning
The error code ERROR_IPSEC_IKE_NO_MM_POLICY with the numeric value 13850 and hexadecimal representation 0x361A signifies that a required Main Mode Internet Key Exchange (IKE) policy is not available. This error typically occurs during the initial phase of establishing an IPsec security association, where the system cannot find a suitable policy to initiate the negotiation process.
Error Details
The Main Mode IKE policy defines the parameters and rules for initiating the IKE negotiation between two peers. When this policy is missing or not configured correctly, the system will fail to proceed with the establishment of an IPsec tunnel or connection.
Usage Context
This error can occur in various scenarios where IPsec is being used to secure network communications. Common contexts include setting up virtual private networks (VPNs), configuring remote access services, and establishing secure connections between network devices.
Developer Interpretation
Developers should interpret this error as an indication that the necessary policy for initiating the IKE Main Mode phase is missing or not properly configured in the system. This can be due to a misconfiguration in the IPsec policies or a failure to apply the required settings during setup.

FAQ
Q: What does this error mean?
A: This error indicates that a required Main Mode IKE policy is not present, preventing the initiation of an IPsec security association.
Q: How can I resolve this issue?
A: Ensure that the necessary IPsec policies are correctly configured and applied. Check the policy settings in the Group Policy Editor or through command-line tools like netsh ipsec set policy.
Summary
The ERROR_IPSEC_IKE_NO_MM_POLICY error is a specific technical issue related to the absence of a required Main Mode IKE policy during IPsec configuration and operation. Developers should focus on ensuring that all necessary policies are properly defined and applied to avoid this error.
