I have opened case #7112044 asking about this last Thursday but nobody has responded yet... We do not use these IP ranges nor do we have Windows XP in our environment.
I have seen this too. We had a new computer show up called 'Test-PC' that we could not figure out where it came from. We ended up deleting it and it hasn't returned. Perhaps it is Sophos doing something on their end?
