Windows XPP has a service for securely connecting across the Internet to an
Office Network called VPN (Virtual Private Networking). I don't believe that
you can do that with WinXP Home edition (though I may be wrong). Also, if
you get XPH, you won't be able to log in to a work Domain. There are
workarounds for this, but it means you have to leave a security hole in your
Work domain. Unless your work network is also a dinosaur, I would recommend
XPP.
