I've got a Lenovo ThinkPad Edge E530 laptop with Windows 7.
As local administrator, and using IE, I can access web sites without any issue. As the user it takes several minutes to open most sites e.g. bbc.co.uk.
I rebuilt the laptop, as there was no obvious cause, and it still does the same thing. We've got several of this model, but only this one is affected.
Any ideas on what could be causing this?
