Vista keeps name server options from previous lease

I realise this is probably not a ISC-DHCP issue, but if anyone has seen
this and can provide insight, I would appreciate it.
Our residence halls have a range where they hand out leases to unknown
clients. They also hand out a name server option different from the
campus ones. This name server redirects all requests to a registration
page. Once registered, the clients get a new lease, with the usual name
servers, and go along their merry way.
We also have a wireless network in the residence halls. What we are
seeing with Vista clients is this: the client picks up a lease from the
wireless network and gets the options for the main campus name servers.
Then, the user plugs into a wired port in the residence hall and gets a
new lease from the dhcp server on that network. However, their name
server option does not get updated. Thus, they don't get redirected to
the registration page, because they are talking to the wrong nameservers.
So, what seems to be happening is that Vista is keeping the name server
options from a previous lease. I haven't been able to find anything in
the archives pertaining to this issue with Vista. Has anyone else come
across it? Is it a Vista bug?
All of the dhcp servers are running 3.0.4.
Thanks in advance.
