When you try to access shared folders created on Windows machine using java based program you may encounter an error Failed to connect hostname/IP Address or if you try to connect the shared folder with IP address the error could be Failed to connect 0.0.0.0<00>
Description: The issue occurs because JAVA program makes call to Windows machine to access the shared folders using SMB V1/CIFS file sharing protocol and if that feature isn’t installed on Windows machine then Java will throw an error.
Resolution: To resolve the issue just install the SMB V1/CIFS file sharing on Windows machine.
Go to control Panel and then Program and Features. Click on Turn on Windows Feature on or Off
Then enable Features SMB V1/CIFS Client and SMB V1/CIFS Server
Please note a reboot is needed to complete the installation of features.
