You should be able to connect to the internet regardless of whether Internet
Explorer works. First thing you need to do is verify you have internet
connectivity. To do this, I'd suggest:
1) Open a command prompt
2) Type "ping 24.56.222.66" and hit <Enter>. If your internet connection is
active, you'll get four replies along the lines of "Reply from 24.56.222.66:
bytes=32 time=13ms TTL=61". Any other replies could indicate a problem with
your connection.
Assuming your connection is OK, fire up your FTP client and download Opera
from the following url:
ftp://simtel.galilei.com/win95/webbrows/ow32enen723.exe. Install. Once you
have an active browser, reference Microsoft Knowledge Base Article 318378

p) for detailed instructions on how to reinstall Internet Explorer under
Windows XP.
If your connection is NOT OK, check back here for additional
troubleshooting. Your installation of IE may not be corrupt at all...
