Ad-hoc peer to peer wireless can't get DHCP

[Alan]

Having followed the whole setup from the MS support site, read all the
manuals etc, I'm stuck with a problem.

I cannot get a laptop to work as a peer to peer ad-hoc network with a net
connected PC also with a wireless card. If I take the laptop to work, it
connects fine to the router, gets DHCP and everything. I can even ping the
ad-hoc connections from each other. But if I set up the net PC as a shared
dun connection, the laptop cannot see the net and no matter how much
ipconfig releasing, renewing and flushing I do, it simply cannot get a DHCP
address, even when I tell it the IP of the pc! And yet if I use a crossover
cable and change the connection in DUN to use the 10/100 LAN connection, ICS
works fine (sorry for all the acronyms!).

Any ideas? I've disabled and re-enabled and rebooted and checked and
rechecked.

Where on your home network is your DHCP server?

On the PC connected to the net - ics allocates DHCP on the dun connection
(IIRC!)

What addresses and subnet masks are being doled out by the ics computer?

For example, at the moment:

Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : mshome.net
Description . . . . . . . . . . . : VIA Rhine II Fast Ethernet
Adapter
Dhcp Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IP Address. . . . . . . . . . . . : 192.168.0.94
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
DHCP Server . . . . . . . . . . . : 192.168.0.1
DNS Servers . . . . . . . . . . . : 192.168.0.1
Lease Obtained. . . . . . . . . . : 15 April 2004 18:45:40
Lease Expires . . . . . . . . . . : 22 April 2004 18:45:40

Which is about what I'd expect. Just can't understand why wireless can't
work with it...

And the laptop is not picking up anything in regards to an address? Can the
wireless card see the network at all? All firewalls are off on all machines
in question?

It's been a while since I set up my adhoc network, but I ran into the exact same problem, it's a firewall issue. assuming you've already checked the 'allow other network users to connect through this connection' in the properties of your connection on you're desktop what you need to do is this: turn off the firewall on your wireless connection (outgoing) and turn on the firewall on your internet connection (incomming), I don't know why this works, but I extrapolate that you're restricted from sharing an unfirewalled connection for some reason.
