To configure the network settings on a Mac open System Preferences and click on the Network icon.
When the Network Preferences appear you will be presented with the option to configure any interface that is installed on the Mac that can be used for connecting to the network.
In most cases this will be the Built-in Ethernet. Double-click on the interface you would like to configure.
As you can see all network settings are done in this window. Make sure to change the Search Domains to include: campus.muc.prv
Most of the other settings are okay as long as you see Using DHCP and the Mac is not receiving a 169.254.x.x address.
