In example scenario below, the "XP" box can also be vista/win7-8-8.1 (maybe even 10), 32 or 64 bit. 
How to keep XP on minimally on network, but not internet, using network only to update time and push files via scp/sftp.
Both old XP and Server are kept safe by closing all ports on XP, and allow that XP computer to connect only to port 37 on a (rfc868 aka "rdate") time-server. The device providing TIME service on port37 should get its own time from internet/intranet (by ntp, etc).
(The time-server does not have run a server-os: it can be almost any linux device, or even a windows-pc.)

With all ports closed on XP, the time-server cannot infect XP. If XP is infected, such as by a usb-key, it cannot spread over
network to time-server (unless time-server has vulnerability known to virus. Turn off smb1 on time-server (if windows)!

On XP/7/8/8.1, rdatesvc.exe (= prdatesvc = PermaSoft Rdate service) safely keeps system time and date correct by periodically from
port 37 on a specified time SerVeR, such time.nist.go

Unlike ordinary pdf files, portfolio.pdf files cannot be viewed on tablets or phones, and most software that can open them is available only on windows or mac, not on linux (until recently). They really should have a different extension like .pdfp or similar. Google finds lots of folks looking to batch convert portfolios to individual files, as the portfolio breaks *lots* of automated workflows, especially if you upload them to systems that can't handle them. If you try to open them in other viewers, like a link in a browser, you'll see a misleading messages ending in "get adobe reader now!", like:

http://dev.datalogics.com/cookbook/portfolios/portfolio-sample.pdf

You get that brain-dead message even if you already have adobe-reader. The work-around is to download the pdf then open in some awful adobe-reader or acrobat software (version 10 or newer is needed, I believe).

If you have a bunch of such pdfs, this is a place folder for upcoming script to batch convert portfolio pdf files.
