Hello @Slickrc23-6900,

Thank you for posting here.

We can check prerequisites based on the information in the following link and establish trust as below:

1. Prerequisites
   

2. Sign in to the Azure portal
   

3. Configure DNS in an on-premises AD DS environment to support Azure AD DS connectivity
   

4. Create a one-way inbound forest trust in an on-premises AD DS environment
   

5. Create a one-way outbound forest trust in Azure AD DS
   

6. Test and validate the trust relationship for authentication and resource access

   
   

For more information, we can refer to the following link.
Tutorial: Create an outbound forest trust to an on-premises domain in Azure Active Directory Domain Services
https://docs.microsoft.com/en-us/azure/active-directory-domain-services/tutorial-create-forest-trust

Other information for your reference.

Hope the information above is helpful.

Thank you for the response. I have followed all guidance by the documentation and get the error in Azure AD Domain Services alert/overview:

There is a problem with the trust for domain <mydomain>. Error: The security database on the server does not have a computer account for this workstation trust relationship.
