I am using a PC as a file server, it's been previously used as a MD. The IP is 192.168.80.2. Problem is, the MD is not listed anymore (which is good), and the IP is not in the unknown devices list, but still the core does not recognize the file server. The software of the file server worked fine on a computer with a different network card. The samba shares of the file server are visible from windows.
Any one have an idea how I can convince the core to take a new look?
