I recently had a problem with a Windows Server 2016 Standard Edition. The motherboard and memory modules were replaced and I had to restore from an image backup from two months earlier.
On bringing up the restored system then the trust relationship between the clients and the server was broken. I followed the normal process of switching the clients to a Workgroup and then re-joining the domain.
Was the trust relationship broken because of restoring an old backup or the replacement of the motherboard ?
Could someone explain how the trust relationship works please ?
