Remove underscore character from hostname/FQDN

Note: If the hostname or FQDN is used elsewhere in your network, ensure to make relevant changes after you’ve removed underscore from the hostname. For instance, make necessary changes to the distribution server or secure gateway server.


As per security standards, there is a stricter validation in place to remove underscore character from the hostname/FQDN. If the character is not removed from either your hostname or FQDN, you will no longer be able to access Desktop Central console.

Steps to change the hostname/FQDN

Follow these steps if you are using a local account:

  1. Open the Run command window by pressing Windows Key + R.
  2. Type sysdm.cpl and press Enter.
  3. Click on the Change button to rename the computer.
  4. Click on Ok and reboot your device when prompted for the same.

To change the computer name in Settings app:

  1. Open Settings and click on the System icon.
  2. From the left panel, click About and under Device Specifications, click on Rename PC.

Steps to update the NAT address using Desktop Central

By default, the NAT address will be the same as FQDN. If you want a different NAT address, make necessary changes to the NAT address in your network. Upon changing, follow the below-mentioned steps for updating the NAT address in Desktop Central:

From Desktop Central console, navigate to Admin tab -> Server Settings -> NAT settings and update the new address.

You’ve successfully changed your hostname/FQDN.

When there is a change in the hostname, ensure that Desktop Central server is reachable via the IP address for hassle-free agent-server communication. Also, if you have an existing certificate with underscore character in the hostname, ensure to get a new one for the changed hostname.
