i am trying to set up a two node MS cluster 2016 with cross forest. currently i am having two separate domains and having trust between domains. like a.com and b.com domains and trust enabled between them. One server is in a.com and another server is in b.com, i want to enable a MS cluster between them. i know we can do Domain-Detached Cluster setup using local accounts. is there any way using with domain account to setup this cluster between the forest.
You can deploy Multi-domain Cluster (Domain-independent cluster). The major thing is to configure DNS-suffix.
Domain-independent cluster cannot be created without using local Administartor account.
