A cloud administrator recently deployed an update to the network drivers of several servers. Following the update, one of the servers no longer responds to remote login requests. The cloud administrator investigates the issue and gathers the following information:
* The cloud management console shows the VM is running and the CPU and memory utilization is at or near 0%.
* The cloud management console does not show an IP address for that server.
* A DNS lookup shows the hostname resolves to an IP address.
* The server is a member of the same security group as the others.
* The cloud administrator is able to log in remotely to the other servers without issue.
Which of the following is the MOST likely cause of the server being unavailable?
