Hi Mukul Padhya,

Thank you for posting your query on Microsoft Q&A.

The error message "Failed to reserve port 6516" typically occurs because another application on your system is already using port 6516.
By default, Windows Admin Center (WAC) uses port 6516 for its web-based management interface. During the setup process, WAC attempts to open this port to facilitate communication between itself and other servers.

Open the Command Prompt with administrative privileges and run following below command.

netstat -ano | findstr :6516 and to check if there any process currently using this port.
If another application is using the port, you may need to stop that application or reconfigure it to use a different port.

Here's what I received when I ran the above command:

netstat -ano | findstr :6516

TCP 172.16.96.56:65168 192.168.3.51:5508 TIME_WAIT 0

No port 6516 is in use. Does Admin Center not recognize the difference between 6516 and 65168?
