Has anyone had good luck serving dhcp addresses to Vista clients
that work reliably?
I have a test system and I can't seem to find out how to
properly get dhcpd to always respond with broadcast instead of
unicast since Vista won't honor unicast dhcp packets.
My Vista (my wife's actually) has no problems with unicast dhcp packets.
Stock dhcpd server in CentOS 5, and Vista Home. Worked without
any special config.
Are you sure that is the problem?
Not sure, but it is one of the suggested problems I see in many
google searches. There are registry edits that help, but I don't
want to have to do a bunch of edits when we get stuck with a
hundred Vista machines. I have plenty of time, for now, to
experiment. There are posts that say the subnet needs to be
authoritative, but mine is. What happens is that the Vista system
will not route outside the local subnet for more than 5 or 10 minutes.
Do you mean that you do get an IP-number and default gateway from the
dhcp server, but after 5 to 10 minutes, the default route setting gets
lost?
To me that would mean that the dhcp is working fine, but something
else kicks in after that time that messes up the dhcp
settings. Any additional firewall software on the laptop, like Norton etc.
Or can you relate the loss of routing to an action on the dhcp server,
like lease renewing etc.
I think I am going to have to spend some more time on this. Maybe
with a sniffer and some patience. The laptop just had Vista Ultimate
because that is the version we acquired for testing, and our
standard McAfee virus scanner. I will have to toss together a VM
machine and try different combos of stuff. As a matter of fact I
have a VM loaded on my laptop that I was playing with at home as it
runs fine there. That way the only difference will be the change
in location. It is just dog slow, but for this test it doesn't
matter that much.
I'll have to look at the troubled machine and see if I can detect
problems in the routing tables and such. I just have to figure out
if the same commands do what I want between Vista and XP, or if I
need to do some reading.
My recent reading has lead me to believe that Windows Vista comes
with IPV6 enabled by default and can really generate some traffic if
you do not turn it off and possibly cause problems if your network
infrastructure does not support it. Is that possibly a problem?
Cheers,
Glenn
