About "about:"!

You might have noticed in most of the browsers that about:blank is the default home page. Have you ever wondered what this page is? Its a blank html page created by the browser. Read this article to know more about "about:".

"about:URI" is a protocol used by browsers to maintain its internal pages. The most common URI used is "blank". The implementation of this protocol is upto the browser. Each browser has its own set of URIs. Some URIs are helpful in knowing some info about the broswer itself.

"about:" - Displays version info in Mozilla firefox, Opera, Konqueror
"about:plugins" - Shows the filename, MIME type, description, suffix, and status of all installed plug-ins in Mozilla firefox
"about:help" - Displays help file in Opera.

Comet - the next stage of AJAX!

Comet is a software concept that enables web servers to send data to the client program (normally a web browser) without having any need for the client to request it. It allows creation of event-driven web applications which are hosted in the browser.

A style of data transmission that is neither traditional nor Ajax

Enabling Remote Desktop Remotely

Lots of sites on the internet discuss how to enable remote desktop in Windows XP and Windows 2003 Server, but the majority of them require you to have physical access to the computer first. So how do you enable remote desktop when you do not have physical access to the computer. It is all to do with the registry!

1. Make a network connection to the remote computer to ensure that you have administrative access to the machine (i.e. \\computer\c$). This will prompt for a username and password of the administrator. Enter the correct details.
2. Start the registry editor regedit.exe (and not the older application regedt32.exe if it exists - it does not in later releases of Windows)
3. Choose File, Connect Network Registry
4. Enter the computer name as above.
5. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server for the registry settings for the remote computer (take care not to select your own desktop)
6. Double-click fDenyTSConnections.
7. Change the value of this setting to 0 to enable Remote Desktop or 1 to disable it, and click OK.
8. If your remote computer has multiple network cards and you want to ensure that Remote Desktop is operating only on a selected card then navigate to the following registry location: (as above)\WinStations\RDP-Tcp and note the LanAdapter value. If this is 0 Remote Desktop operates on all networks, and if this is another number then it operates only on the network as identified in the (as first)\lanatable registry key
9. Disconnect the remote computer from the registry editor using File, Disconnect Network Registry, and selecting the correct remote computer in the list.
10. Finally, one of two options. Option A is quicker:
    1. Connect with  Manage Computer to the remote PC (right-click "My Computer", choose "manage", right-click "Computer Management (Local)" and "Connect to another computer". Enter the name of the remote computer). Then from the Services node, start the Remote Desktop Helper service. This will cause Remote Desktop to start and read the relevant registry key. This is particularly helpful because it allows one to get Remote Desktop working without even restarting the machine.
    2. If this fails, then you can always restart the computer remotely.
