问题
we disabled smbv1 in our windows machine and now we can't connect using smb2 we are using commons-vfs2(2.0) and commons-vfs2-sandbox(2.0) here is my code:
@Test
public void testConnection() throws FileSystemException {
String folder = "\\\\10.0.0.0\\smb";
folder = folder.replaceAll("\\\\", "/");
StringBuilder builder = new StringBuilder(128).append(Protocol.CIFS.getProtocolPrefix()).append(':')
.append(folder);
String fileURI = builder.toString();
System.out.println(fileURI);
FileSystemOptions fsOptions = null;
String password = "mAdmin";
String username = "myPassword";
String domain = "";
StaticUserAuthenticator auth = new StaticUserAuthenticator(domain, username, password);
fsOptions = new FileSystemOptions();
DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(fsOptions, auth);
FileSystemManager manager = VFS.getManager();
FileSystemManager fileSystemManager = manager;
FileObject fileObject = fileSystemManager.resolveFile(fileURI, fsOptions);
boolean result = fileObject.isReadable();
System.out.println(fileURI +" " + result);
}
this is how I disabled smb v1
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB1 -Type DWORD -Value 0 -Force
How I enabled SMBV2
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB2 -Type DWORD -Value 1 -Force

in case we are enablying SMB1 it's working

Unfortunately commons-vfs2 does not support the SMBv2 protocol. The only open source implementation currently of an SMBv2 client is SMBJ. Using SMBJ you could connect as follows to your share:
SMBClient client = new SMBClient(SmbConfig.createDefaultConfig());
Connection c = client.connect("10.0.0.0");
Session s = c.authenticate(new AuthenticationContext("myAdmin", "myPassword", "");
DiskShare share = s.connectShare("smb");
