Windows 11 mewajibkan <strong>SMB Signing<\/strong>, yaitu tanda tangan digital pada setiap koneksi SMB untuk mencegah manipulasi data di tengah jalur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Masalah muncul ketika server menggunakan <strong>Guest Access<\/strong> (akses tanpa autentikasi). Mode ini tidak kompatibel dengan kewajiban SMB Signing, sehingga koneksi diblokir meskipun secara teknis klien sudah terhubung ke jaringan.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Kebijakan<\/th><th>Fungsi<\/th><th>Kondisi default Windows 11<\/th><\/tr><\/thead><tbody><tr><td>SMB Signing<\/td><td>Tanda tangan digital pada setiap koneksi SMB<\/td><td>Diwajibkan<\/td><\/tr><tr><td>Insecure Guest Logons<\/td><td>Penerimaan koneksi tanpa autentikasi<\/td><td>Diblokir<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Perbaikan dilakukan dalam dua tahap: mengizinkan koneksi guest melalui Registry, lalu menonaktifkan kewajiban SMB Signing di sisi klien melalui PowerShell.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Langkah 1 \u2014 Izinkan SMB Guest Access lewat Registry<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Registry adalah database pengaturan sistem Windows. Langkah ini mengizinkan Windows menerima koneksi guest yang tidak terautentikasi.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Tekan <strong>Win + R<\/strong>, ketik <code>regedit<\/code>, lalu tekan <strong>Enter<\/strong><\/li>\n\n\n\n<li><p>Arahkan ke lokasi berikut di panel kiri:<\/p><code>HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\LanmanWorkstation\\Parameters<\/code><\/li>\n\n\n\n<li>Di panel kanan, cari nilai bernama <code>AllowInsecureGuestAuth<\/code><\/li>\n\n\n\n<li>Jika belum ada, klik kanan area kosong \u2192 <strong>New<\/strong> \u2192 <strong>DWORD (32-bit) Value<\/strong> \u2192 beri nama AllowInsecureGuestAuth<\/li>\n\n\n\n<li>Klik dua kali nilai tersebut, ubah angkanya menjadi <code>1<\/code>, lalu klik <strong>OK<\/strong><\/li>\n\n\n\n<li>Tutup Registry Editor<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Langkah 2 \u2014 Nonaktifkan Kewajiban SMB Signing lewat PowerShell<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">PowerShell adalah antarmuka baris perintah Windows untuk konfigurasi sistem tingkat lanjut. Langkah ini menonaktifkan kewajiban SMB Signing khusus di sisi komputer klien.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Klik <strong>Start<\/strong>, cari <strong>Windows Terminal<\/strong> atau <strong>PowerShell<\/strong><\/li>\n\n\n\n<li>Klik kanan, pilih <strong>Run as administrator<\/strong><\/li>\n\n\n\n<li>Periksa kondisi saat ini:<br>Get-SmbClientConfiguration | Select-Object EnableInsecureGuestLogons, RequireSecuritySignature<\/li>\n\n\n\n<li>Jika <code>RequireSecuritySignature<\/code> bernilai <code>True<\/code>, nonaktifkan dengan perintah berikut:<br>Set-SmbClientConfiguration -RequireSecuritySignature $false -Force<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Langkah 3 \u2014 Restart dan Uji Koneksi<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Restart komputer agar semua perubahan diterapkan. Setelah menyala kembali, tekan <strong>Win + R<\/strong>, masukkan alamat server jaringan, lalu tekan <strong>Enter<\/strong>:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\\\\192.168.1.2<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Folder sharing seharusnya sudah dapat diakses.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Verifikasi<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Untuk memastikan perubahan sudah berlaku, buka PowerShell sebagai Administrator dan jalankan:<\/p>\n\n\n\n<pre class=\"wp-block-code has-palette-color-5-color has-palette-color-3-background-color has-text-color has-background has-link-color wp-elements-1\"><code>Get-SmbClientConfiguration | Select-Object EnableInsecureGuestLogons, RequireSecuritySignature<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Hasil yang diharapkan:<\/p>\n\n\n\n<pre class=\"wp-block-code has-palette-color-5-color has-palette-color-3-background-color has-text-color has-background has-link-color wp-elements-2\"><code>EnableInsecureGuestLogons : True\nRequireSecuritySignature  : False<\/code><\/pre>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Troubleshooting<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Jika folder masih tidak dapat dibuka, periksa dahulu apakah server dapat dijangkau dari komputer Windows:<\/p>\n\n\n\n<pre class=\"wp-block-code has-palette-color-5-color has-palette-color-3-background-color has-text-color has-background has-link-color wp-elements-3\"><code>ping 192.168.1.2\nTest-NetConnection 192.168.1.2 -Port 445<\/code><\/pre>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Hasil<\/th><th>Arti<\/th><th>Tindak Lanjut<\/th><\/tr><\/thead><tbody><tr><td><code>ping<\/code> gagal<\/td><td>Server tidak terjangkau di level jaringan<\/td><td>Periksa kabel, IP, subnet, dan gateway<\/td><\/tr><tr><td><code>TcpTestSucceeded : False<\/code><\/td><td>Port 445 (SMB) tertutup atau diblokir<\/td><td>Periksa service SMB di server dan firewall<\/td><\/tr><tr><td><code>TcpTestSucceeded : True<\/code><\/td><td>Port SMB terbuka; masalah ada di konfigurasi folder sharing di server<\/td><td>Periksa konfigurasi share dan permission di sisi server<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Catatan Keamanan<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Langkah-langkah di atas hanya direkomendasikan untuk jaringan rumah atau kantor yang sudah terpercaya. Menonaktifkan SMB Signing di jaringan publik membuka celah keamanan, karena lalu lintas SMB menjadi rentan terhadap manipulasi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Setelah akses guest tidak lagi dibutuhkan, kembalikan pengaturan dengan menjalankan perintah berikut di PowerShell Administrator:<\/p>\n\n\n\n<pre class=\"wp-block-code has-palette-color-5-color has-palette-color-3-background-color has-text-color has-background has-link-color wp-elements-4\"><code>Set-SmbClientConfiguration -RequireSecuritySignature $true -Force\nSet-SmbClientConfiguration -EnableInsecureGuestLogons $false -Force<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Untuk keamanan jangka panjang, pendekatan yang lebih disarankan adalah menggunakan akun Samba dengan username dan password khusus. Dengan autentikasi user, SMB Signing tetap aktif dan jaringan tetap terlindungi.
