You just can’t deny the convenience of using remote control while watching your favorite programs on TV.

For a network administrator, nothing is better bliss than remote control tool that he can use for administering and troubleshooting his networked computers.

Remote control tools were available since the days the concept of network computing born. Software like Symantec’s PCAnywhere and Altiris’s Carbon Copy were proven remote control tool available since long, and were considered cute babies for system administrators; yet they did not get mature enough for mass use. However, with the introduction of Windows terminal service and Windows XP Remote assistance tool, the concept of remote computing gets redefined and had got a new ways of life. Remote computing concept were further added support from web based tool like GoToMyPc through which you can control virtually any computer connected to Internet form anywhere and at any time. Now imagine the scenario that you don’t need to carry even your laptop to access your PC running your application at your workplace or home. You simply have to use web services like GoToMyPc or Control F1 to connect your computer across Internet; for example, you can just walk in to a Cyber Café at Ratlam from where you can access your workstation and run applications; that is installed at your office in New Delhi, that too without making any configuration settings!

Some positive traits of Remote Computing..

Barring some security issues, Remote Computing gives you various benefits that include:

  • Full control over remote computer is possible from anywhere in real time.
  • Applications, regardless of Operating System, as some remote control tool like VNC support; can be used from anywhere as true, flexible hot-docking environment– but beware you may violate application license agreement while using application installed in a system that is not allowed to be used at other locations. In general, remote control tools perform and execute applications remotely at the client end where they are legally installed. They simply transmit the display and other output thus generated to host end. Hence you are actually using the application exactly where it is installed and if user is same, then there may not be any such problem like license violation will arise.
  • Remote computing tool provide you facility of remote system administration and troubleshooting.
  • Both the support personnel and end user can see the problem and its solution in real time.
  • Remote tools provide you faster problem resolution and more effective support desk.
  • Remote system administration improves customer service.
  • These tools can be effectively used in cutting cost in business having large networked environment.
  • Remote tools can be used as effective educational tool in illustrating things interactively and in real time over remote computers.
  • Remote control tools allow you to snoop over the other computers you want to look at. It can act as a short of closed circuit television that allows you to view other computers screen in real time with or without knowing the user. With these tools, organizations can tab a watch on their employee that what they do in their computer in business hour. Further, these screen actions can be recorded as movie files along with keystrokes and mouse click logs as evidence.
  • You can run heavy and intensive task on a remote machine that has faster processor, more memory or has fewer jobs compared to your own. Remote control tool can also be used as resource sharing tool.
  • You can share your documents in real time with others at remote end.
  • Remote tools such as WindowsXP Remote control can provide real time online interactive support with the help of simple applications like Outlook and MS Messenger.

It appears that Remote control tools are going to be a necessity in future computing. But not before solving some serious security issues that comes while using Remote Computing. Remote tools are notorious in by-passing security such as firewalls. Further, securities are managed by remote control tool provider and applications and hence you have to depend on them. Some Remote Control tools may provide you strong security settings such as allowable login attempts, time and date to login and secured password authentication etc. yet they may not be reliable enough. Once a computer is set to be used with remote tools, a hacker or an un-authorized person can sneak in, disguise himself and can take full control of that computer. Using applications remotely through remote tools may violate software license. Looking to all these facts, remote control architecture my not be used for convenience and an alternative to application portability.
