I need to resolve hostnames using IP address. I have tried various options and nothing has worked. By GetHostName() returns the IP but not return the computer name. I read that with the library JCIFS can access the NetBIOS name of the remote machine. It's what I need. But I can't find anywhere the complete library, I have the jcifs.jar but I don't have the jcifs.xml. Anybody can help me?
