On local I have installed IIS7, MSSQL2005Express, Visual Web Developer 2008, latest JAVA. Any idea? Please help :)

There are a ton of security settings to optimize with vista, they can really put a hurt on your internet connection especially when sending HTTP requests and other client-server communications. Do a google search for vista optimizations, and see what you can find. Also vista 32 bit is not the optimal OS in my personal opinion, your not gaining anything from running vista in 32 bit, but are consuming tons more resources when compared to XP. I think though if you do a few optimizations to vista you will resolve the issue, but its not directly related to anything DNN site, its more of fine tuning well cutting out vistas middle man management systems.
