I understand the difference between an outgoing and an incoming trust
I understand that the trust flow goes into one direction and the direction of access is the other way around
I understand that being the domain with an incoming trust, we are the ones who can access the other domain
I understand that being the domain with an outgoing trust, we are the ones who get accessed
Now I am doing a forest recovery and have to reset one side of the trust for security purposes as outlined in this Microsoft document: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/manage/forest-recovery-guide/ad-forest-recovery-reset-trust
The root domain in the forest obviously has both incoming and outgoing (two-way) trust relationship to its child domains. Now the following part of the Microsoft documentation I do not understand.
Reset the password on only the trusting domain side of the trust, also
known as the incoming trust (the side where this domain belongs).
Then, use the same password on the trusted domain side of the trust,
also known as the outgoing trust. Reset the password of the outgoing
trust when you restore the first DC in each of the other (trusted)
domains.
I fail to understand which trust I have to reset, being in the root domain. The incoming ones? The outgoing ones? Do I have to do anything on the other side, in the remote domain?
