You can get Java to resolve NetBIOS names by using the JCIFS library. You can get it from http://jcifs.samba.org/. Add that to your project and then use code like this to convert a host name to an IP address.
import jcifs.netbios.NbtAddress;
...
NbtAddress nbtAddress = NbtAddress.getByName(hostname);
InetAddress address = nbtAddress.getInetAddress();
String ipAddress = address.getHostAddress();
Most likely pc259
is not defined in you DNS server, but is a NetBios hostname (see http://en.wikipedia.org/wiki/NetBIOS#NetBIOS_name_vs_host_name).
I don't think Android can resolve these kind of hostnames - you'll need to add this computer to the DNS repository.
