Looking for opinions on keeping them connected to the internet (or any other opinion you want to throw in there). Thanks.
I found a hack to allow XP machines to download updates. Check it out at this link:

I tried the windows update site with one of my XP computers before I installed the hack, and there were no updates available. After I made the change, there were several available.
If it's not connected to the Internet, using XP is perfectly safe. Our cluster runs all of our AudioVault machines on XP. Much better than a Windows 7 machine if you only have 2 GB of RAM.
I would imagine that there has to be a good anti-virus package out there that continues to support XP....
