I am on a Windows network with a Windows 7 machine.

For some strange reason, when I run ipconfig, I see that I have the wrong DNS suffix for my network adapters, e.g. def.companyname.com as oppsed to abc.companyname.com.

My colleagues next to me, who are on the same network, have the correct suffix.

Where does the problem originate, and is it something I can fix on my machine (and if so, how?), or is this something a network administrator must resolve? (I did ipconfig /release and /renew, but that did not help).
