Problem: schannel Event ID 36882
We receive these “error level” secure channel untrusted certificate authority errors constantly on a bunch of servers.
SChannel Event 36882: The certificate received from the remote server was issued by an untrusted certificate authority. Because of this, none of the data contained in the certificate can be validated. The SSL connection request has failed. The attached data contains the server certificate
Solution: schannel Event ID 36882
Try checking the servers to make sure that they have the appropriate root certificate chain installed (root ca and if there is a policy/intermediate ca, as well as its own cert). If not, you will need to download the certificate chain from the certsrv page and install that to each of the servers – this can be done via GPO if desired.
