1 The Clients can receive their TCMS configuration via **DHCP option 210**.
2 To enable this, create a new DHCP option with **ID 210** on the DHCP server. Set the data type to **“String”** and use the following syntax for the value:
3
4 **<TCMS-Server-IP-Address>:<AdditionalApiPort>**
5
6 The additional API port is optional. It can be configured in the [[basic settings >>doc:Handbuecher.TCMS11\.00.Kapitel 5 - Den TCMS einrichten.5\.E\. Bearbeiten-Menü.5\.E\.A\. Einstellungen bearbeiten.5\.E\.A\.G\. Basiseinstellungen.WebHome]] of the TCMS.
7
8 On the Thin Client, the required TCMS settings are automatically applied by the setup wizard during initial startup. Alternatively, the settings can be configured manually. To do so, enable the option
9 {{status title="Remote-Administration"/}} → {{status title="TCMS Settings"/}} → {{status title="obtain via DHCP"/}}.
10
11 Once the TCMS settings are configured, the Thin Client will automatically be added to the *Temp Group* during its first login to the TCMS.
