Creating an Ad-Hoc Network?

I know this has been asked before, but I can't find a solution. I want to set
up an ad-hoc network on my online PC so I can share its Internet connection.

The set up proceeds for a while, then I get an error message "Windows could
not set up <name of network>".

I've tried different security details, I get the same message.

Review procedure for ICS (Internet Connection Sharing) - compyers must be
members of the same workgroup - default is MSHOME.

Sorry, but I don't see the relevance of either of these points.

I have not got to the ICS stage, it's the set-up of the ad-hoc network that
causes problems. Similarly, the workgroup is not the issue, it's not a
problem connecting to the network, it's a problem with creating the network.

Also, the default is WORKGROUP, not MSHOME.

Apart from that, 10/10

Is this vista to vista, wired or wireless, if you can provide more
details will enable more specific help

Wireless.

Sorry I must be missing something you need at least 2 pc's to have a
network, you can do the preparation work but untill you actually have
two devices that can detect each other no vista ad-hoc network can exist

Surely there must be a stage where you set up the network on one PC, then a
second stage where you connect to it with another PC? I cannot do the first
stage.

Ok it may be a problem with the terminology.
An Ad-Hoc wireless network in vista is a function to create a temporary
link between two computers in order to share files, for example it may
be used to transfer from one laptop to another during a business meeting
where the two computers are not normally on a network.

the first question I need to ask is how do you connect your existing
laptop to the internet? If this is done wirelessly using a router then
you already have a network and all you need to do to get access to the
internet on a new computer is run the internet connection wizard on each
additional computer.

You can use a computer to perform this router function, but to do so
you will need Two network cards in the computer. This is of course a
normal thing in today's laptops. What you would need to do is Connect
the Ethernet wired port on the laptop to the broadband modem and set up
your internet connection, then run the Internet connection sharing
wizard to allocate addresses to the other computers on the wireless
side.

In all cases all the involved devices (or at least two) need to be
present in order to set up the network

Sorry, but I don't believe this. How can you set up a network between two
PCs where you have to configure them both at exactly the same time?
