Vista doesn't ack dhcp offer

With what the logs and the dump are showing, the OFFER is never getting to
the client. It does not seem to be leaving the server, even though the logs
say it is. We had a similar problem when running v3.1.0 on a Tru64 box. The
"client" was a Cisco Wireless LAN controller. XP clients worked fine and we
did not have any Vista machines at the time. We moved the server to a Linux
machine and things work fine. This does not explain why the registry hack in
the client fixes the problem, but the issue is strangely similar and the
packet captures look identical, as do the logs.

By system firewall... you mean the server or the client? Definately not the
issue with the client...applying the registry hack found here:
....fixes the problem without any further changes to the server or client.
But, doing this to every vista instance is simply impossible, I need the
server to somehow understand, and reply back with what the client expects,
to come back.
