Description

After Disabling SMBV1 in windows I can't access into the filesystem.
This code works when SMB1 is enabled, but sops to work once disabled.

@Test
    public void testConnection() throws FileSystemException {
		String login = "admin";
		String password = "password"; 
		String domain = "";
		String folder = "//10.0.0.0/smb";
		folder = folder.replaceAll("\\\\", "/");
		StringBuilder builder = new StringBuilder(128).append("smb").append(':').append(folder);
		String fileURI = builder.toString();

		FileSystemOptions fsOptions = null;

		StaticUserAuthenticator auth = new StaticUserAuthenticator(domain, login, 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
