How can you confirm connectivity to the domain controller for adding a workstation?

Using the command "ping dc01" is a direct and effective way to confirm connectivity to the domain controller. The ping command sends Internet Control Message Protocol (ICMP) echo request messages to the specified hostname—in this case, "dc01"—and waits for a response. If the command returns replies, it indicates that the workstation can reach the domain controller over the network, confirming connectivity.

While checking network status through settings, running a diagnostic tool, and verifying the server name are useful steps in ensuring overall system health and configuration, they do not directly provide immediate feedback regarding the connectivity to the domain controller. The ping command is specifically designed to test communication between devices in a network, making it the most straightforward and efficient method for this purpose.
