If you have general questions or problems relating to IT, we recommend taking a look at the knowledge base on the new service portal: https://service.fu-berlin.de/servity/km/ussknowledgebasearticles/ 

This portal provides a compact and clearly structured overview of the IT knowledge available at FU Berlin, which can be searched using keywords.

If the articles there do not help you or if you have more specific questions, you can report a problem or submit a request via the ticket system on the service portal's homepage.
