Hi. I have several user accounts on my pc. Two of them will connect to the internet with no problems (broadband connection) but for some reason the others won't. I've not installed any new software, virus software reports no problems etc etc. Any help would be really appreciated and as I'm no expert it would be great if it could be really clear and step by step - many many thanks in advance for any advice - I'm going grey and bald trying to work this out. xx
