Troubleshooting Event 36876 Source Schannel


Users could not change theirs password and this event was logged on system. The form to change was developed by another team and runs over Apache.

Source: Schannel

Category: None
Event ID: 36876
Date: Date
Time: Time
User: N/A
Computer: YourComputerName
The certificate received from the remote server has not validated correctly. The error code is 0x80090328. The SSL connection request has failed. The attached data contains the server certificate.

Error Code 0x80090328 = SEC_E_CERT_EXPIRED (Certificate is expired).

After check in theĀ  Root Authority Certificate I’ve notice that the Domain server certificate, had been renewed, and found this KB;en-us;839514, that has all information to solve the “change password issue”

To resume:

This issue occurs because LDAP caches the certificate on the server. Although the certificate has expired and the server receives a new certificate from a CA, the server uses the cached certificate. You must restart the server before the server uses the new certificate.

Plan a reboot to the date of certification renew, in my case every year.

Hope that this information can help you.
