After installing Windows Vista RC1 5600 on some of my machines I am facing problem with the lan connectivity. The data transfer on that is extremely slow with poor internet connectivity. I had newly installed the OS and there was no problem with the setup. I had updated all the drivers. I think there is some problem with the internal configuration. I had tested sites like microsoft.com which works very well, but other websites takes a long time to load and then I get a error. I had configured the settings properly but still the lan is working extremely slow. Any idea on the same how it really can be fixed.
