Once it is done, for the trust to work we must need to take the certificate from the DC and need to import it in the local (SharePoint server where we are trying to add a domain certificate )Certification Authorities (Root) certificate store .

For that first we need to take the certificate from the machine which has the AD certificate Service role enabled. By default it will be located under here: (Extension of the file will be .crt)


Once you got the certificate now you can go ahead and import it in the root certification authorities folder. For that do the following.

1. Start –> run –> type “mmc”

2. It will open a console window, from the file menu select “Add/Remove Snap in”

3. Select the “Certificates” snap in and add it.

Add or Remove Snap ins

4. Once it is done then import the certificate to the “Trusted Root Certification Authorities”

“A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. 0x800b0109”
