There are numerous exploits for IIS that need to be patched before you can make your system public. Since your system may become infected before you have a chance to fully patch it (highly likely), you'll have to install Windows while you are offline, install the patches (which you would have had to download from another machine and put on CD or something), and then you'll be safe to go online.
