Hi all,
My computer doesn't show the Lan icon on the taskbar.
I have gone through the taskbar properties but there is also no option for lan icon on taskbar.
How it is disappeared.
Simultaneously, my broadband lan connection icon is also disappeared from taskbar when connected.
I have done lan connection properties that show notification icon when connected.
But my computer gets connected too but the icon doesn't displayed on taskbar.
Please help.

Open "Network connections" in control panel. Locate your LAN connection. Right-click on the connection and select "Properties". At the bottom of the form, check "Show icon in notification area when connected."

Perito,
Yes I have done that too.
But no use.
Any other thing.

Anyone tell me that which file is responsible for placing lan icon in the taskbar or registry entry for the same.

I see that you aren't alone with this problem. Here are some Microsoft links. Unfortunately, it looks like it might be quite a bit of work to fix.

I also wondered if the Iconcache could be screwed up. This is the file from which the icons are drawn. System icons, including tray icons, are often pulled from that file. You can try to fix it by simply deleting IconCache.db which is usually found in /Documents and Settings/[Username'/Local Settings/Application Data). Once you delete it, it will be automatically recreated when needed. Delete all of the IconCache.db files that you can find on your computer.

On browsing the web, I noted that a number of people were giving up and reinstalling Windows. That's kind of a last resort, I would think.

Good luck. You may need it.

Have you tried disabling your lan connection, then creating another one, and enabling the new one?

Hi,
Take a right click on the network neighborhood and select the properties then, select the internet connection icon and again take a right click and go to properties and it will show on the bottom, select the notification connect icon. Press OK.
