Installing NIS on VistaHome Premium 64Bit

I have NIS on my Netbook and I am very pleased with it.  I just bought a new laptop and I want to install NIS on it.  Are there any Vista programs such as the firewall that I need to turn off prior to installation or does NIS automatically take care of that?

 

Thanks.  This is probably a pretty basic question but I'm a "late adapter" and this is my first computer.
