Help with the automatic activation of Microsoft products

In order for the Microsoft software to automatically activate, the system hast to find the license server. A license service is running under Windows which asks the DNS-server about the license server. 

DNS-Suffix is required

The system consults the DNS sever for the license server under Windows. In oder to do so, the system needs to enter with the DNS suffix that was registered for the institution at the RRZK.

For the special case that institutions do not own a registered DNS suffix wich is registered at the RRZK (like the medical department or a local DNS administration is used), the order in which the DNS suffixes are searched for has to be changed.

Computers of institutions who use the DHCP service (automatic distribution of IP addresses) offered by the RRZK, will receive their DNS suffix automatically.

For the manual distribution of IP addresses, it is important to not only enter the name of the computer but also the registered DNS suffix.

Example: : 
In this case, galileo ist the name of the computer and the DNS suffix of the RRZK. Of course, you have to use the suffix of your own institution with your computer.

Establishing the DNS suffix

  • Start the control panel of your computer (Windows logo (from Windows 8 onwards you have to right-click on it) and then control panel)
  • click on "system" in your icon view

  • click on "change" next to "full computer name"
  • choose the tab "computer name"
