I'm having problems connecting to the Internet via Cable modem at school and at home via DSL.  I keep getting the same message "Limited or No Connectivity", and it always will get stuck at the Acquiring IP address window.  I've installed all the updated patches and even contacted Dell.  I went to a computer repair shop, and they told me they had no problem accessing the Internet, that the problem was with my cable company.  When I contacted my cable company, they told me it was a corrupted file in my system, but everything worked. I have no problem connecting wirelessly to the Internet.  It's not just my Ethernet card either, I tried going out and buying a USB-Ethernet adapter and I still got the same message, so the problem is somewhere within my software.

 

Anyone have any solutions??  I'm trying to avoid a complete reinstall of XP, but I may have to do that.
