Running Windows 2000 Professional as a Web Server.

I was planning on using my extra Windows 2000 Professional box as a Web Server to host my web page; however, I had one question about hosting my own web site from my own Web Server.

I have about 5 computers on a SOHO (Small Office Home Office Network all networked and one of them I just added (Windows 2000 Professional).

I also have a VOIP phone on the network.

The router is a Linksys WRT54GS encrypted with WPA Personal-TKIP.

Question: How safe is it to run a Web Server
from this given network. I am more worried about the security related with adding and running a Web Server from home.
