How Do I Remove Broken or Stale Trust Relationships between Two Domains?

Hello All,

I came new into an existing AD environment. I wish to know the procedure by which I can remove all broken or stale Active Directory Trust Relationship between two domains.

I am getting errors in SCOM (AD Monitor Trust) on some DCs stating: The trusts between this domain(my domain) and the following domains(s) are in an error state: external-domain(inbound), the error is: The specified domain either does not exist or could not be contacted. (0x54B)

I dont want to set overrides but I just want to spot all these broken trusts and flush them from AD.

Thanks.
