After doing maintenance on Cisco UCS Server Profiles I had to fix up network adapters on a 4 node Hyper-V Failover Cluster.  After the maintenance 3 of the 4 nodes came online.  Errors in the event log included cluster service termination due to file already exists.   After checking all settings on the 4th node and doing a cluster validation that showed all was OK I was ready to scratch my eyes out when I came across an article that advised to rename all of the network connections used by the cluster and then try to start the service again.   Low and Behold!   Issue resolved.
