The best way to meet this requirement is to create a PowerShell script to disable the RDP service on all Windows-based servers within a data center. PowerShell is a scripting language and command-line tool that can be used to automate tasks and manage Windows systems remotely. A PowerShell script can use cmdlets (commands) and parameters to perform actions on multiple servers at once, such as disabling a service or changing a configuration setting. RDP (Remote Desktop Protocol) is a service that allows remote access and control of a Windows system through a graphical user interface. Disabling RDP can improve security by preventing unauthorized or malicious access to the servers.

Explanation
The server is not joined to the domain is causing the issue. A domain is a logical grouping of computers that share a common directory database and security policy on a network. Active Directory is a Microsoft technology that provides domain services for Windows-based computers. To use Active Directory credentials to log on to a server, the server must be joined to the domain that hosts Active Directory. If the server is not joined to the domain, it will not be able to authenticate with Active Directory and will only accept local accounts for logon. To join a server to a domain, the administrator must have a valid domain account with sufficient privileges and must know the name of the domain controller that hosts Active Directory.

Explanation
Constant replication is a type of replication in which all files are replicated, all the time. Replication is a process of copying data from one location to another for backup, recovery, or distribution purposes. Constant replication is also known as real-time replication or synchronous replication. It ensures that any changes made to the source data are immediately reflected on the target data without any delay or lag. Constant replication provides high availability and consistency, but it requires high bandwidth and low latency. Application consistent replication is a type of replication that ensures that the replicated data is consistent with the state of the application that uses it. It involves quiescing or pausing the application before taking a snapshot of the data and resuming the application after the snapshot is taken. Application consistent replication provides better recovery point objectives than crash consistent replication, which does not quiesce the application before taking a snapshot. Synthetic full replication is a type of replication that involves creating a new full backup by using the previous full backup and related incremental backups. It reduces the backup window and network bandwidthconsumption by transferring only changed data from the source to the target. Full replication is a type of replication that involves copying all data from the source to the target regardless of whether it has changed or not. It provides a complete backup of the data, but it requires more storage space and network bandwidth than incremental or differential replication. References:
