|First off, you should be reinstalling from your "recovery disc" or "recovery partition", not from an install you created. This is the only way to be sure you get the proper drivers for the hardware. That's the thing about brand name computers, you usually can't just do a "generic" install and have all the devices work properly. Brand names tend to be proprietary because it keeps the customers coming back.|
Alternatively, if you're going to insist on using your own XP install (btw, SP 3 is the most recent SP so you should redo your slipstreamed install disc using that SP) you should first download all drivers for your computer from Dell's website before reinstalling. Then you have them handy for when you're done the initial install.
You also need to verify your account is indeed "static" (as versus "DHCP) and also your TCP/IP Settings with your ISP once you have the network interface working properly.
The last thing I'm going to say is, if you have more than one computer connecting to the internet, do yourself a favor, spend the money on a SOHO Router. If you have wireless capable clients, buy a wireless capable router.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
