How do i download network adapter for my dell tower, its service tag is C0WST21

You can download the bus and device drivers from Dell WEB site, the support download page. Make sure you select your model desktop or laptop, better still, type in the Service Tag number, it is printed on the label on the bottom of the laptop and on the back or sides of a desktop. (If the Service Tag label is missing then go into the BIOS setting and on one of the BIOS pages, the Service Tag number will be displayed). This will open the page where the specific drivers for your model computer are located. Also make sure you select the Windows of the drivers for your Windows operating system.

Hi,
The error message states that the drivers for your network adapter are not installed. You can either use a dell drivers and utilities disc to install the network drivers or can go to http://support.dell.com/support/downloads/ and can select your computer model and entering your service tag number (located on desktop) and can install drivers.
Good Luck!

Dell install different network card in the same model laptop, and most likely you have installed the wrong driver. I suggest you download the driver using the Service Tag number.

If Device Manager has a yellow ? against the network adapter then either the network card driver is corrupted or was not installed.
I suggest you install the network driver.

My pc lan card is showing connected to LAN but it's not communicate with domain or not open ie also. please give me suggetion.

go to dell.com, under support you can put in either your service tag number or model number and then you will be able to download not only the network adapter driver, but all the drivers you need.

If you are reinstalling a driver, it is typically best to go with the newest version of that driver. The best way to get the newest drivers is directly from Dell.
If your desktop does not have internet without this driver, download the file (as follows) on another computer and move it to your dimension and install (as follows).
Browse to Dell's driver download page:
http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=gen
There will be a service tag somewhere on the tower of your Dell 3100 desktop, type in this service tag on the product identification page. Note: the drivers here may not be applicable if you have upgraded your computer's hardware since purchasing it.
Be sure to choose the correct operating system you plan on running on this machine. Under category you can select "Network". This will bring up all of the network adapter drivers. Select the first driver labeled "Dell Utility" which applies to the wireless USB adapter.
Choose the "Download" button and save the driver to your computer. Double click this file and follow the onscreen instructions to install the software.
Your wireless internet device should now work!

look for your service number on the tower, go to dell support site put your model number or service tag number in, this should show what your computer came with from factory and show the driver list for your computer...http://support.dell.com/support/topics/global.aspx/support/product_support/product_support_central?~ck=ln&c=us&cs=19&l=en&lnki=0&s=dhs&SystemID=DIM_CEL_1100
