Hello,
sometimes i’ve been asked why the Hostname of a IGEL Linux based Thin Client is not entered in a Microsoft based DNS Server. The reason for this is mostly quite simple, the DHCP Server is not configured to handle none Windows devices and to update the DNS records for these devices. Means you need to provide credentials to the DHCP Server to update the DNS records, see also here: http://technet.microsoft.com/en-us/library/cc775839(v=ws.10).aspx
