Installing javascript driver Mongodb-native on Windows server 2008

I have nodejs running with mongodb database and i'm trying to install the javascript driver mongodb-native.. When i try "npm install -g mongodb --mongodb:native"

I tried installing the same configuration on a Windows 7 machine and it works just fine. Any idea why it is not working with Windows server 2008 ?

here is the output i get from the npm install command:

npm http GET https://registry.npmjs.org/mongodb
