Windows Vista RC1

I finally took the plunge and installed Vista on my laptop the other day. So far it’s been pretty good, but one thing thats really bugging me is that for some reason when I’m connected to the network at work, internet access via our proxy is slow as hell. Access to internal sites is fine, and if I use the same computer and the same user account from home, without a proxy, theres no problem. It also happens if I am at home and use VPN to connect to the work network. Prior to connecting in, everything is fine. As soon as I’m connected via VPN, and have to go through our proxy, its slow as….

Wierd. I’m not sure at this stage whats causing this. It doesn’t seem to matter which browser I use – IE7 does it, but so does Opera 9.02…

So far I haven’t found anything on the net that sounds like my problem, or at least, nothing which provides a resolution…\
