How do I tell if Shadowing is Allowed or Prohibited on a Server?

Citrix XenApp Server products allow Farm Administrators and Users to interact with other user sessions.

Shadowing can be a useful tool for user collaboration, training, troubleshooting and monitoring. This capability is useful for supervisors, help desk personnel, teachers, and anyone else who may need to examine another user's session.  During Setup, you can limit or disable shadowing.  You can disable shadowing of ICA sessions on all servers in a farm if, for example, legal requirements prohibit shadowing of user's sessions.  Or, you may want to disable shadowing on servers that host sensitive applications such as Human Resources or Payroll.

During Setup, you will see this dialog box:

The decision made on this screen cannot be changed without reinstalling XenApp.  This is from page 66 of the XenApp 4.5 with Feature Release 1 (AKA XenApp 5.0 on Server 2003):

Important: Shadowing restrictions are permanent. If you disable shadowing or
enable shadowing but disable certain shadowing features during Setup, you
cannot change the restrictions later. Any user policies you create to enable user-to-
user shadowing are subject to the restrictions you place on shadowing during
Setup. Do not disable shadowing as a substitute for user- and group-specific
connection policies.

Prohibit shadowing of user sessions on this server. Select this option to
permanently disable shadowing of user sessions on the server. If you disable
shadowing during Setup, you cannot enable it using other Citrix Presentation
Server configuration utilities or by creating connection policies.

The problem that an Accidental Citrix Admin will have is how to tell if shadowing is Allowed or Prohibited on a server they now manage?  Whether shadowing is Allowed or Prohibited, all shadowing components are still installed. 

• The cshadow.* and wshadow.* program files are still installed in C:\Program Files\Citrix\System32
• The Shadow Taskbar is enabled
• Citrix policies for shadowing can still be created and applied.

So how does the Accidental Admin determine if shadowing is Allowed or Prohibited? Well, you will start with the Terminal Services Configuration Console. Within the console, under the Connections node, examine the Property sheet for the ICA-tcp object. When the Property sheet is displayed, click on the ICA-settings tab. 

The following screen shot shows what the ICA Settings look like when shadowing is Allowed:

In the bottom area there is a Shadowing section that allows Shadowing to Inherit user config or set to:

• is disabled
• is enabled: input OFF, notify OFF
• is enabled: input OFF, notify ON
• is enabled: input ON, notify ON

When shadowing is prohibited:

When shadowing is Prohibited during the installation of XenApp, the Shadowing section of the ICA Settings is grayed out.

This was tested in my lab using XenApp 5.0 on Server 2003.

System Administrator Appreciation Day

A sysadmin unpacked the server for this website from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong. All to serve this webpage.

A sysadmin installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.

A sysadmin makes sure your network connection is safe, secure, open, and working. A sysadmin makes sure your computer is working in a healthy way on a healthy network. Asysadmin takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.

A sysadmin worries about spam, viruses, spyware, but also power outages, fires and floods.

When the email server goes down at 2 AM on a Sunday, yoursysadmin is paged, wakes up, and goes to work.

A sysadmin is a professional, who plans, worries, hacks, fixes, pushes, advocates, protects and creates good computer networks, to get you your data, to help you do work -- to bring the potential of computing ever closer to reality.

So if you can read this, thank your sysadmin -- and know he or she is only one of dozens or possibly hundreds whose work brings you the email from your aunt on the West Coast, the instant message from your son at college, the free phone call from the friend in Australia, and this webpage.

Show your appreciation

Friday, July 29, 2011, is the 12th annual System Administrator Appreciation Day. On this special international day, give your System Administrator something that shows that you truly appreciate their hard work and dedication. (All day Friday, 24 hours, your own local time-zone).

Let's face it, System Administrators get no respect 364 days a year. This is the day that all fellow System Administrators across the globe, will be showered with expensive sports cars and large piles of cash in appreciation of their diligent work. But seriously, we are asking for a nice token gift and some public acknowledgement. It's the least you could do.

Consider all the daunting tasks and long hours (weekends too.) Let's be honest, sometimes we don't know our System Administrators as well as they know us. Remember this is one day to recognize your System Administrator for their workplace contributions and to promote professional excellence. Thank them for all the things they do for you and your business.

Shutdown Otomatis pada komputer

Ketika kita menggunakan komputer, seringkali kita acapkali meninggalkannya. Hal tersebut terjadi, mungkin saja karena ketiduran, asik ngobrol, ada acara lain, ke rumah teman, dan sebagainya.

Bila hal ini sering terjadi, bisa saja PC komputer anda mengalami ngambek atau sakit karena sering di cuekin. So, Obatnya apa yah ? Pada tutorial dibawah ini, anda bisa mengetahui bagaimana sih agar komputer kita secara otomatis melakukan shutdown pada waktu yang telah ditentukan. Semua ini, anda lakukan tidak perlu menggunakan perangkat lain, cukup windows anda dan yang pastinya tidaklah sulit untuk dilakukan.

Berikut 5 (lima) langkah-langkah mudah tersebut :

Pertama, klik menu Start dan pilih RUN atau anda cukup melakukan klik Windows + r.

Kedua, untuk melakukan perintah Shutdown otomatis, langsung saja anda ketik tsshutdn AA / Powerdown atau tsshutdn AA saja (AA adalah waktu rentang periode shutdown yang anda inginkan dalam hitungan detik). Contohnya : anda ingin mematikan komputer anda 1 menit kemudian atau 1 jam kemudian, tinggal anda ketik tsshutdn 60 (1 menit) atau tsshutdn 3600 (1 jam). Kemudian klik OK.

Ketiga, maka timbullah pesan dari Command Prompt anda, yaitu System is Shutingdown in 60 seconds (1 menit) atau 3600 seconds (1 jam).

Keempat, seandainya anda ingin menggagalkan perintah anda tersebut, tinggal anda klik Ctrl + C untuk membatalkannya.

Kelima, Bila anda tidak ingin menggagalkan perintah tersebut, biarkan jendela windows itu Open, atau lakukan minimize saja, karena apabila di Close, maka perintah anda tersebut gagal atau Timer-nya tidak akan berjalan.
