i've had this problem for a bit now. whenever i open up IE it just will not detect an internet connection. it works on every other desktop on this computer but not mine. i've been using opera ever since it stopped working. i'm using windows XP. i have been to the microsoft website to try and find a solution but there's no help there, i'm just going around in circles. can anyone help?
Ok- a couple of quick things I'd try, given that it's only your current account that's having problems:
1. Log in as an administrator, create a new user account, log out of the administrator account, and:
a) log in to the new account and verify that all of your programs (including Internet Explorer, obviously) work properly. If they do:
b) Log out of that account, log back in under an administrator account, and copy the contents of your C:\Documents and Settings\Old_Username folder to your C:\Documents and Settings\New_Username folder (instructions for doing so are here). If you get prompts asking if you want to overwrite existing files/folders in the New_Username folder, click Yes.
c) Repeat step "a)".
If all seems to be well you can delete the old account, although I'd leave it in place for a while just in case.
(Just FYI: My suggestion of creating a new user account was more of a test than anything else. User accounts do get corrupted sometimes, and it helps to know if a given problem is global, or just limited to one user account, as that narrows down the possibilities.)
