networking doen't work for windows guests, linux guests do

[travishein]

I currently have virtual box 1.6.0 on slackware linux 12.

am able to boot and run both linux and windows guests, that is nothing crashes on me.

however i can't seem to get any mode of networking to work for windows guests.

the host is currently set up with bridged network, i do the usual manual setup of eth0, tap1 as interfaces to the bridge br0

ifconfig eth0 up promisc
brctl create br0
brctl addif br0 eth0
dhcpcd br0
tunctl -t tap1 -u myuser
brctl addiff br0 tap1

# then start virtualbox as myuser

So the same virtual machine profile, when i boot it with a linux live cdrom, the dhcp client inside the linux guest finds the ip address, where as when i boot windows (2000) in the guest, it does not get an ip address.

windows has the guest utilities installed, it does see the AMD PCNET Family PCI Ethernet Adapter,.

I tried manually setting an ip address in the windows guest, still no luck.

Im mostly sure it is not a network or host settings problem, since the virtual bridged mode network does work when I start up linux guests.

really stumped, am I crazy, or does this kind of thing happen to other people too.

Ok, more reading in other posts for different problems relating to networking. One of them said to try using the Intel PRO/1000 MT desktop as the adapter type for the virtual machine setting. For some reason, in my case trying that i get a virtual box error "invalid network adapter type 3,

But I was able to change it to PCnet-PCI II type (the default was PCNet-PCI III).
And that did work a bit better, but stopped working right away.

I was using the 1.6.0 open source edition. I found that by just getting the 1.6.4 not open source edition it seems to now work wit the default network device,

so it is quite possible that the open source edition i had compiled was not built right when I did it, or it had some issues at the time i built it.
