While I'm still extremely interested in fixing this issue this is certainly a viable workaround until then and ping's options certainly lend itself to be used this way. Sadly I think our LAN admins are not much interested in playing around with the VLAN config even if it turns out to be misconfigured since it works for most of the network clients. By the way, we're actually using fairly expensive networking gear (Cisco and the like) so you'd expect it would all work _really_ well. Hmm, well maybe not ;-) Thanks for the feedback. ::mark
