Side note, at one point in time, while working on a bunch of XP home and
professional machines, going to services.msc and disabling upnp didn't
always work.  Since you don't really need it or want it, you should fully
remove it from the system.  In other words, after disabling it and
rebooting, port scan the machine.  There is/was a utility that'd remove upnp
completely, but i forget where it is (i found it on google).  Being a *nix
head, I can't tell you exactly how to completely remove it, but i'm sure
someone here can.

Port 5000 TCP is used together with port 1900 UDP for UPnP (universal plug
and play). It is open on a default Windows XP install.
If you don't use it (and you probably don't) you can easily disable the
mentioned ports from listening by opening 'services.msc' from a run box and
stop the folowwing services:
'Universal Plug and Play Device Host' &
'SSDP Discovery Service'. Be sure to set them to 'disabled' or 'manual' to
prevent them from starting up on a reboot.
http://www.grc.com has a nice article about this too.

Sincerely

I had reason to look at a Windows XP box and discovered port 5000 open
on
it.  Subsequent research has shown that this is normal (albeit stupid).

However, when I connect to port 5000, I get an "HTTP/1.1 400 Bad
Request".  Also, fport /ap shows port 5000 open, but will not associate
an
application with it.  Am I overly paranoid or has this box been
compromised?

Thanks
