WAN issues

[martin]

I have XP boxes in different locations on my WAN, but for
some very annoying reason my XP machines will just loose
their network connection and after a while it will come
back. We have found that to if you ping the machine's ip
from itself then ping outside to a remote ip it kicks back
in to life. I have the same fault in different offices
connected to out WAN but only with XP machines, so I know
it something to do with XP. Has anyone ever come across a
similar problem and more importantly how to you fix it.
