# FQDN

The server will require an FQDN that is resolved by all endpoints that are needing to run OSD via the DeployR server.

When joined to an Active Directory Domain, this is typically all automatically done as part of the domain join and DNS process, however when doing a workgroup device, additional steps might be required. This page will go over how to configure a workgroup DeployR server setup for the FQDN / DNS.

Example, the DeployR server is named 'dr', it is a work group server, and the domain name is 2pintlabs.com. On the server, dr.2pintlabs.com is set as the FQDN, and the DNS also configured so the clients can find the server based on the FQDN.

The certificate will then also be set to the FQDN so all communications will go through that FQDN URL.

Set the DNS suffix on the computer name too:

In addition, also set the BackConnectionHostNames:

Computer\HKEY\_LOCAL\_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1\_0

An additional item that can be done to help in specific situations when trying to do things locally on the server is to set an entry in the local hosts file.

1. Open **Notepad as an Administrator**
2. Navigate to: `C:\Windows\System32\drivers\etc\hosts`
3. Add a new entry mapping:
   * The **internal IP address** of the server
   * To the **external FQDN**
4. Ex: 10.1.1.16      dr.2pintlabs.com
