Explanation
If the server is not reachable by name but can be accessed by IP address, it means that there is a problem with name resolution. The hosts file and the DNS server are both responsible for mapping hostnames to IP addresses. Therefore, the server administrator should check these two files for any errors or inconsistencies that might prevent the server from being resolved by name. References:

Explanation
The most likely cause of the issue is that the server has not been joined to the domain. A domain is a logical group of computers and devices that share a common directory service and security policy. A domain controller is a server that manages the domain and authenticates users and computers that want to access domain resources. To log on with domain credentials, a server must be joined to the domain and registered in the directory service. If a server has not been joined to the domain, it will not be recognized or authorized by the domain controller.

An IP KVM (keyboard, video, mouse) is a device that allows remote access and control of multiple servers over a network using a web browser or a client software. An IP KVM is a cost-effective option to administer and troubleshoot network problems locally on the servers, as it eliminates the need for physical presence or dedicated hardware for each server. A management port (A) is a network interface that is used for out-of-band management of network devices, such as routers or switches. A management port does not provide local access to servers. A crash cart (B) is a mobile unit that contains a monitor, keyboard, mouse, and other tools for troubleshooting servers in a data center. A crash cart requires physical access to each server and may not be cost-effective for many racks of servers. A KVM (D) is a device that allows switching between multiple servers using a single keyboard, video, and mouse. A KVM does not provide remote access over a network and requires physical connection to each server. References:

Explanation
The component that allows for a connection of devices to both sides inside of a blade enclosure is midplane. A midplane is a board or panel that connects two sets of connectors or devices in parallel with each other. A midplane is typically used in blade enclosures or chassis to provide power and data connections between blade servers on one side and power supplies, cooling fans, switches, or management modules on the other side. A midplane can also act as a backplane by providing bus signals or communication channels between devices.
