Membuat prioritas bandwidth untuk Zoom di Mikrotik
* Membuat address list server zoom, server zoom menggunakan port 3478,3479,5090,5091,8801-8810, jadi kita tandai dahulu koneksi yang menggunakan port tersebut dan ip tujuannya disimpan kedalam address list.
/ip firewall mangle
add chain=prerouting dst-address-list=!zoom_ip dst-port=3478,3479,5090,5091,8801-8810 protocol=tcp action=add-dst-to-address-list address-list=zoom_ip;
add chain=prerouting dst-address-list=!zoom_ip dst-port=3478,3479,5090,5091,8801-8810 protocol=udp action=add-dst-to-address-list address-list=zoom_ip;
* Menandai setiap koneksi baru yang menggunakan akses ke port 3478,3479,5090,5091,8801-8810 baik tcp ataupun udp.
/ip firewall mangle
add chain=prerouting protocol=tcp dst-port=3478,3479,5090,5091,8801-8810 action=mark-connection new-connection-mark=koneksi_zoom passthrough=yes;
add chain=prerouting protocol=udp dst-port=3478,3479,5090,5091,8801-8810 action=mark-connection new-connection-mark=koneksi_zoom passthrough=yes;
* Menandai port 80 atau 443 yang digunakan oleh address list Zoom.
/ip firewall mangle
add chain=prerouting protocol=tcp dst-port=80,443 dst-address-list=zoom_ip action=mark-connection new-connection-mark=koneksi_zoom passthrough=yes
* Menandai Packet Zoom, menggunakan tanda zoom koneksi yang sebelumnya dibuat diatas. Tanda Packet ini yang nantinya akan kita pergunakan untuk dibuat bandwidth managementnya
/ip firewall mangle
add chain=forward action=mark-packet connection-mark=koneksi_zoom new-packet-mark=paket_zoom passthrough=no
* Membuat queue
/queue simple
add name="Queue ZOOM" target=10.88.44.0/24 parent=none packet-marks=paket_zoom priority=1/8 queue=default-small/default-small limit-at=0/0 max-limit=100M/100M burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s bucket-size=0.1/0.1
add name="LAN" target=10.88.44.0/24 parent=none packet-marks="" priority=8/8 queue=default-small/default-small limit-at=0/0 max-limit=100M/100M burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s bucket-size=0.1/0.1

Hai,
Sudah lama ternyata tidak membuat tulisan di blog ini. Sampai akhirnya blog ini mulai seperti mati suri.
Sebagai tulisan pertama gue setelah hiatus, gue mau share kejadian tadi di kantor.
Tadi pagi ada sesebapak atasan yang manggil gue untuk dilakukan pengecekan terhadap aplikasi Microsoft Excel beliau. Keluhannya adalah formula Excelnya error dan karena beliau juga ga fasih bahasa indonesia dan gue pun ga fasih bahasa bapak itu, akhirnya kita diskusi dengan bahasa bahu. wkwkwk.....
Setelah dicek, ternyata error yang dimaksud adalah sebagai berikut :
Terlihat bahwa Formula penjumlahan yang ditampilkan menggunakan format R1C1 Style.
Langsung ga pake lama, gue lakuin ini :
- Buka Tab File, Pilih Options.
- Di menu Options, pilih Tab Formula
- Pada menu Working with Formulas, matikan ceklis pada pilihan R1C1 reference style.
dan Voila,, Microsoft Excelnya kembali normal dengan tampilan seperti biasa.

IBM Thinkpad Secure Drive Red Blinking
I have a task from my user about his Thinkpad secure drive. The Secure Drive is look like the picture below.
His Secure Drive always show blinking red repeatedly, and he cannot input the password to unlocke well. From first impression, this conditions means the secure drive come into locked mode. and i think it's cause by he always put the worng password over and over again.
To get into unlocked mode, i do the following action :
1. Disconnect the secure hard drive from your computer.
2. Hold 5 while reconnecting the secure hard drive to your computer. The status LED alternately flashes in red and in green.
3. Press 5278879 and Press OK. The status LED turns red, indicating that the secure hard drive is unlocked for additional password attempts.
For further informastion, it can read at this documents.

Fatal error C0000034 applying update operation xxx of .....
Dari sekian banyak komputer berupa desktop dan laptop, ada sebuah kendala yang menurut gue cukup unik sehingga perlu gue catat agar tidak lupa kalau terjadi kembali. Kendala tersebut adalah munculnya pesan "Fatal error C0000034 applying update operation ................" yang terjadi saat windows restart setelah selesai melakukan update.
Setelah gue lakukan pencarian, gue menemukan kasus serupa yang diajukan disebuah forum milik Microsoft. Langsung aja gue kutip dari situs tersebut cara penanganannya.
When applying SP1 for windows 7 there is a specific error that can happen during reboot. If you get this error “Fatal Error C0000034 Applying Update Operation 282 of...”, follow the steps below to fix the SP1 installation
1. Reboot your computer while it’s starting up.
2. When your computer starts up again, choose the option “Launch Startup Repair”"If you do not have this module installed in the OS, you'll need a Win7 install disc that is the same architecture (i.e. 32 or 64-bit) as the OS installed. Just boot to the CD and go from there."
3.When the Startup repair starts, click cancel.
4. After you click cancel it will show a box. Click “Don’t Send”, then click the link “View advanced options for recovery and support”
5. In the new window click Command Prompt at the bottom.
6. In Command Prompt type this and press enter: %windir%\system32\notepad.exe
7. Notepad will open. In notepad go to File - Open.
8. Change the type of files notepad views from .txt to All Files
9. Now in Notepad, go to C:\Windows\winsxs\ (or whichever drive Windows is installed on)
10. In that folder, find pending.xml and make a copy of it"Just copy and paste it in the same folder, this is just in case something happens to the original so you don't lose it."
11. Now open the original pending.xml"It will usually take a while to load because it's a huge file."
12. Press CNTRL+F and search for the following exactly: 0000000000000000.cdf-ms
"That's sixteen (16) zeroes ;)"
13. Delete the following text (yours may be a little different):
"NOTE: Your PC might not have all 3 sections of code (, , ). Just make sure you delete section “Checkpoint” and whatever other sections have “000000000000000.cdf-ms”. They will be right next to eachother."
14. Save the file, close notepad, close command prompt, restart your computer.

MS. Exchange 2013 - You don't have permission to perform this action - Stuck in draft Folder OWA
Running out of ideas, I checked settings of send connector, just to make sure there is nothing out of ordinary. I see this in Send Connector properties,
Ooops, there are external DNS Server setting. I run several NSLOOKUP test and found DNS server did not respon any queries. I think this is the problem cause.
To remove it, you have to run
Set-TransportService -ExternalDNSAdapterEnabled $true -ExternalDNSServers $null
After restarting the transport service, all mails in the Draft folder are gone. Mail flow is restored!
Note :
If this action did not solve the issue, try to disable your Antivirus that installed on your Server. Sometimes, Antivirus blocked Microsoft Exchange services and will cause this issue.

Konfigurasi DC dengan NTP Server Eksternal
Namun setelah pengecekan lebih lanjut, ternyata jam di server AD pun menggunakan local CMOS dan tidak melakukan sync ke server NTP.
Untuk menghindari hal-hal yang mungkin kurang diinginkan dikemudian hari, gue lakukan sinkronisasi dengan server NTP milik pool.ntp.org. Langkah-langkah yang gue lakukan adalah sebagai berikut :
1. login kedalam Server DC yang memiliki role sebagai PDC. Untuk melakukan pengecekan role server lakukan dengan perintah "netdom query fsmo"
2. Buka command prompt dengan level administrator
3. Tambahkan peer server yang ingin dipergunakan dengan perintah w32tm /config /manualpeerlist:"1.id.pool.ntp.org,0x1 1.asia.pool.ntp.org,0x1 3.asia.pool.ntp.org,0x1"
4. Agar Server DC ini menjadi sumber yang dapat dipergunakan, tambahkan perintah berikut "w32tm /config /reliable:yes"
5. Restart service "net stop w32time && net start w32time"
6. Cek status dengan "w32tm /query /status"
Beberapa perintah lain yang mungkin membantu ketika melakukan konfigurasi ini :
a. Memaksa proses sinkronisasi seketika
w32tm /resync /nowait
b. Cek konfigurasi NTP
w32tm /query /configuration
c. Menampilkan sumber NTP
w32tm /query /source
d. Menampilkan konfigurasi Peer NTP dan Statusnya
w32tm /query /peers
