'Connection with server was reset' error when downloading files

Hi,

I am having ongoing issues downloading files from various websites using

either IE7 or Safari on Vista Business on a HP laptop. The download gets to

around 8mb and then hangs for approx 2 minutes before the error message box

pops up saying the 'Connection with the server was reset'.

I use Windows Live One Care and have tried turning the firewall off, turning

the firewall off in my router and even set up a second router but always get

the same result.

Colleagues at work can access the same files without issue on XP machines

with One Care installed so as I've tried 2 browsers and 2 routers I'm

thinking the issue is with my Vista set up somewhere.

Any help appreciated.
