“ The cluster resource ‘SQL Server (SQL2012)’ could not be brought online due to an error bringing the dependency resource ‘SQL Network Name(VSQL2012)’ online “

 During the SQL 2012 Failover cluster installation,  faced the issue on bringing the SQL cluster virtual instance name online and its due to the lack of permission of the main cluster core server name computer object in AD to the  SQL virtual computer object.

Open the Active Directory Users and Computers and look for the virtual computer object which was created for the SQL cluster resource instance and add the cluster computer object with full permission and try to bring the resource online.
