I Installed Sharepoint 2016 on premise in a Windows Server 2016, however the installation used the machine's name to generate the url, so currently when I open my Central Administration of Sharepoint I have a very unfriendly url like:


And everything is using this domain, so if I access to my sites I have http://win-8si9e41b3h3/sites/projects.

How can I change it to something like:

Generally, the central admin URL would be with below format after installing the SharePoint:


Here the port number will be the one that you have given during the installation.

The MSDN article says CA port number can be changed using the below PowerShell command:

Set-SPCentralAdministration -Port 8282(example - you can give your own number)

MSDN Source:


You can try the above step.

And also we can change the central administration URL by other ways:

How to change the URL for SharePoint Central Administration site


it is recommended that you need to create a separate web application (other than CA) for regular use. CA web application is back-end work and it is only provision on 1 server and if you have multi-server environment then it will not provision on other servers ( Web front ends).

what i recommend:

  1. Create DNS Alias which point to the server or Load balancer
  2. Create a Web Application in the Central admin and use the DNS in it
  3. Create a root level site collection
  4. Update the AAM via central admin

Lastly, in your case, you have to backup the existing Site collection and Restore it to new web application.
