Silent deploying RealVNC. Free Installation And Administration In A Computer Network

In a network based on Microsoft operating systems, administrators need sometimes that besides Remote Desktop tool offered by the manufacturer that allows remote access on any network computer station to use other access tools to allow them to interact with user because Remote Desktop block user access as long the administrator access remote that station. I know there is a tool provided by the manufacturer that require an email account on Hotmail or MSN based on launch and acceptance of invitations but it allows the user to determine the level of interaction with the managed station.
Thus appeared free tools which gives administrator the ability to establish rules for remote access and interact with the user directly on the working environment it works. In this way the administrator can view real-time event on a station or applications that a user may complain that not working properly. Often these solutions are used by consulting software firms as teaching tools, and user can view certain steps to be followed for operation of installed applications.
Among the most popular remote access solutions:
- TeamViewer - http://www.teamviewer.com/download/ - developed by TeamViewer GmbH
UltraVNC - http://www.uvnc.com/download/ - developed under a free project by UltraVNC
- TightVNC - http://www.tightvnc.com/download.php - developed by TightVNC Group
Although some of the solutions may be easier to solve what I will present in this solution, I was stopped at the free version of RealVNC solution given the high degree of its use in different networks.
Because the free version of RealVNC application does not allow remote installation of the product on network stations or its management, I will present how you can install and manage free (without using other software with money) a free version of RealVNC product.

Silent Uninstalling/Removing AVG 8.xx over the network

Since late last year more than 200 stations in the network were infected with Brontok virus whose signature was not recognized at all Symantec product although it was a version dated 2005, creating big problems on infected computers, we decided not to prolong acquisition Symantec product which for us was a big disappointment and purchase another more efficient AntiVirus suite.
So we decided to install the freeware version of AVG 8.xx product on all affected stations until the new AntiVirus suite was to be acquired
All well and good until we purchase the new product which could not uninstall AVG product on network stations.
About a week searching the Internet and on various forums to a solution, I created an own method for automatic silent removal by all stations AVG product that requires no user interaction.
Since AVG does not offer support for freeware versions, we found the tool AVG8_Kleaner produced by Kaspersky Lab as automatic removal of the product succeeded only problem is that network users don't have permissions to install and uninstall software on workstations.
Because Microsoft created runas command but without the possibility writing password on the command line, I found a product file called Runasspc free developed by Robotronic that allow to specify the password, even it's encryption.
Next I present the steps to be followed:
