I haven't, will give that a shot the next time this happens.
The DHCP server would be a good candidate (172.16.0.2).
I do get the "destination host unreachable" message, which generally to
me means that my network link isn't active/alive.
And just to confirm my own sanity (or a small piece of it), I *can* ping
the gateway when things are behaving nicely.
I'm tempted to suspect a switching issue of some sort, but have no solid
grounds for doing so.
