Well, your first problem is that you haven't given enough information
for us to know for certain. :-)

If Windows XP is only on the machine where it's not finding any
interfaces, then the problem might be that you have WinPcap 2.2
installed on the machine.
If Windows XP is on all of the machines, perhaps you installed WinPcap
2.2 on the machine with the problems but WinPcap 2.3 beta on the
machines not having the problem.
What you should do is:
uninstall WinPcap on the machine where Ethereal isn't finding
any interfaces;
use the "Search" option to search for files or folders (or
whatever that option became on NT 5.1^H^H^H^H^H^HWindows XP, if
they renamed it between NT 5.0^H^H^H^H^H^HWindows 2000 and
Windows XP) to see whether, after uninstalling WinPcap, you have
any files named "packet.dll" or "wpcap.dll";
if you do have any, remove them;
then download WinPcap 2.3 beta - *NOT* WinPcap 2.2 - and install
it on the machine.
(Yes, you should do all of that. People have had problems that turned
out to be due to more than one version of the WinPcap libraries being
installed, which caused no end of confusion, as Ethereal was using one
version of the library and couldn't find interfaces, while WinDump was
using another version and could find interfaces. We want to make
*absolutely sure* you don't have more than one version of WinPcap
installed, and making sure you have no versions installed, and then
installing one version, will do that.)
Then try Ethereal again.
If it finds your interfaces, the problem was you had WinPcap 2.2, which
does *NOT* work on Windows XP, installed, rather than WinPcap 2.3 beta,
which does work on Windows XP. (The Ethereal download page points this
out.)
If it doesn't find your interfaces, then download WinDump:
http://netgroup-serv.polito.it/windump/
and try that. If it doesn't find your interfaces, either, then it's
probably a WinPcap problem; report it to
winpcap@xxxxxxxxxxxxxxxxxxxxxxx
