Examples described herein may provide cluster check services which may determine whether at least one infrastructure dependent virtual machine (e.g., at least one domain controller and/or at least one DNS server) is located outside of a cluster. In this manner, the storage utilized by at least one of the infrastructure dependent virtual machines may not be part of the cluster itself, which may reduce and/or avoid failure and/or downtime caused by unavailability of the service(s) provided by the infrastructure dependent virtual machine.
