she cant log in on any of her sites like yahoo or ext. on HER COMPUTER.. but she can go to any other computer and log in any of her sites with no problem.. its just her comp. she cant log into... whats the deal?? and advice?? thanks.

It could be a number of things. Firewall or Cookies most likely. She may have her computer set on no cookies and sometimes that could cause it. Or you may have your firewall to senistive. It could be that your IE needs to be updated. That is my 2 cents, I hope it helps.
