Make sure your hostname "sbrdbt01" and FQDN "sbrdbt01.tap.pt" both resolve to the same ip address and the same for the reverse(PTR).

Thank you for your help!

We were able to solve this issue yesterday by ourselves. I wish I'd post it sooner though!

Solution:

A PTR record for the system was missing on the DNS machine.

Include both A and PTR records (DNS, Reverse DNS) for the specified SAP system on the company's DNS system.
