For the failed node always follow these
Disconnect node from domain to work group and readd back to domain and ensure don't modify any network settings.
Run the system software user settings via config wizard.
Go to node admin str in As2 select as1 node definition click connect so due to this your affinity settings remains
Run afwsct -c to check and correct errors if any.
Avoid "Add/Remove" node as far as possible.
Replace the failed node, join domain, apply System Software User Settings then use "Connect Node" in Config Wizard or Node Definition aspect.
Check health of Node Administration Structure with:
C:\> afwsct -s "Node Administration Structure"
If errors are found, add "-c" parameter to attempt repair
