OK. So he wants a web server.
Windows 8 is, in general terms, a Desktop system that can can used for a variety of applications. Including use as a web server.
My point was that a typical small business would not leave a computer on 24/7 unless they had enough workload to justify the additional costs.
However, you did not say it was a small business. I just made an assumption.
A reliable web presence, if that is a high priority, can be rented for under $10 per month, at a remote location which has its own routine maintenance. The amortized cost of running a quality web server on your own location is more that $10 per month. That is why I asked about the intent. A local server is best suited for local file sharing and
Intranet, not
Internet service.
This may help explain what I mean.
