Florian,

Any hostname that you need to connect using TCP/IP must be reachable via
ping from the command line. NetBIOS names are not the same as TCP names.
With TCP/IP the name MUST resolve to an address using a hosts file or
DNS lookup.

You may need to add the target host's address into your hosts file or
add it to your DNS (preferrable option) so that your computer can
resolve the name to the IP address.
