It pains me to say this because his tact is non-existent, but I agree with Rainer here.<br>

If you are using DHCP, you should never be introducing potential
caching issues. If there is such an unreliable system that this
happens often, either use static IP or something like zero config to
fall back. Reusing a stale lease is never a good solution.<br>
<br>
If it is on the wrong subnet, you have one of three options. It
works, it doesn't work, it doesn't work and the routers start sending
notifications to the IT guy that wrong subnet traffic is on the
wire. In the 99.9999% times where you are still on the same
subnet, why the heck did you DHCP server go away?<br><br><div><span class="gmail_quote">On 8/21/05, <b class="gmail_sendername">Josef Wolf</b> <jw@> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
