The Network Device Enrollment Service (NDES) provides a way for devices that do not have an identifier in Active Directory (for example, network devices such as routers, switches, printers, thin clients, or smartphones and tablets) to request certificates from a certification authority. For a more detailed description, see the article "Network Device Enrollment Service (NDES) Basics„.
Example events
At least one of the certificates for the Network Device Enrollment Service has expired. Verify that both the encryption and signing certificates are valid and restart the service.
Description
Occurs when the Registration Authority certificates for the NDES server have expired and there is no replacement. Occurs in conjunction with Event #31 on.
The solution is this, apply for new Registration Authority certificates and then restart the NDES service.
Safety assessment
The security assessment is based on the three dimensions of confidentiality, integrity and availability.
Since in most cases the Registration Authority certificates of the NDES server are requested and renewed manually, an alert should be issued in any case to avoid any impact on availability.
