User CUCM cannot access CUCM Self Portal

Tadi pagi dapat info dari teman yang standby di kantor, bahwa ada user yang tidak bisa mengakses url CCM User miliknya untuk menambahkan speed dials. Informasi yang di peroleh, bahwa tidak ada hak akses untuk user tersebut.

Saat ini di kantor menggunakan CUCM versi 11.

Dari error diatas, diketahui bahwa sepertinya user yang dimaksud tidak memiliki groups CCM End User. Dan benar saja, ketika di cek tidak ada group tersebut.

Langsung saja gue infokan ke teman untuk menambahkan group CCM User, dan akhirnya user tersebut sudah bisa mengakses laman dari user portalnya sendiri.

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

HYPER-V : Device eth0 does not seem to be present, delaying initialization

Pagi-pagi gue mendapat telepon dari team Customer Service ISP yang dipakai oleh kantor, menginformasikan kalau mailserver milik kantor terdeteksi mati. Bergegas gue lakukan pengecekan, setelah terhubung dengan server host Hyper-V, gue coba cari status dari mailserver gue

# ifconfig

dan ditemukan kondisi bahwa tidak ada interface ethernet yang dipakai saat ini.

 lo Link encap:Local Loopback
 inet addr:127.0.0.1 Mask:255.0.0.0
 inet6 addr: ::1/128 Scope:Host
 UP LOOPBACK RUNNING MTU:65536 Metric:1
 RX packets:0 errors:0 dropped:0 overruns:0 frame:0
 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqueuelen:0
 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)


Kemudian gue coba lakukan restart service

# service network restart

hasilnya malah mendapatkan pesan ini

Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization

Asumsi gue, interface ethernet ini mati. Gue langsung coba untuk menyalakan kembali dengan menggunakan perintah

# ifup eth0

masih mendapat pesan yang sama

Device eth0 does not seem to be present, delaying initialization

Ternyata masalah ini terjadi karena MAC Address yang di pergunakan failed.  solusinya cukup mudah yaitu mengganti MAC Address untuk Server ini dari sebelumya dynamic menjadi static.

Tidak bisa Install Printer di Windows 10 - The hash for the file is not present in the specified catalog file.

Gue mengalami masalah ketika melakukan instalasi driver printer yang sudah cukup lama di OS Microsoft Windows 10, dimana ketika proses instalasi mencapai installing printer, selalu tampil semacam EULA dari windows yang menginformasikan adanya perubahan di sistem. ketika gue tekan pilihan "YES", selalu tampil pesan seperti ini :

Windows encountered a problem installing the driver software for your device.Windows found driver software for your device but encoutered an error while attempting to install it.The hash for the file is not present in the specified catalog file. The file is likely corrupt or the victim of tampering.

Setelah dilakukan ujicoba secara brutal, gue menemukan kesimpulan bahwa masalah ini terjadi karena Windows mencegah instalasi aplikasi yang tidak terpercaya (dalam hal ini driver printer sudah cukup tua). Fitur ini sudah ada sebenarnya sejak windows 8, yang bernama "Device Driver Signing", dan setelah gue cari-cari di beberapa forum komunitas IT, gue temukan solusinya dibawah ini.

1. Tekan tombol "Start"
2. Ketikkan “startup”.
3. Pilih “Change advanced startup settings“.
4. Pilih “Restart now” pada bagian “Advanced startup” 
5. Kemudian komputer akan restart, dan menampilkan menu "advanced startup"
6. Pilih “Troubleshoot“.
7. Pilih “Advanced Options“.
8. Pilih “Startup Options“.
9. Pilih “Restart“.
10. Komputer akan kembali restart, dan akan menampilkan menu lebih lanjut
11. Setelah menu tampil, pilih angka "7" untuk memilih “Disable driver signing enforcement“.

Setelah gue lakukan hal diatas, printer tersebut sudah sukses diinstall di notebook baru ini. Dan sudah siap tempur di user.

Fatal error C0000034 applying update operation xxx of .....

Dampak dari serangan masif ransomware yang bernama WannaCrypt, membuat gue harus berangkat pagi-pagi ke kantor untuk melakukan instalasi patch pada komputer user yang berbasis Micrososft Windows.

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

My client said they cannot sent any E-mail and stuck in draft folder when they are using OWA. It's also give an error "You don't have permission to perform this action". They have troubleshoot for  whole day and found no idea to resolve it.

When I started looking at the issue, I went through series of basic transport troubleshooting steps for Exchange 2013 multirole server, such as checking all transport related services, possible back pressure issue, and state of all server components. Of course, there is nothing wrong with them.

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,

There are no reason to use external DNS, For this environment, it's not needed as well. I've unthick the box but the problem still exists. 

I then run get-TransportService | fl *dns* to make sure that we don’t have any external DNS settings configured.

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.
