Does a peer-to-peer network always set up an administrative share (c$),
giving it almost complete access to all the machines in the workgroup?  Is
there a way to share part of a hard disk, but not all, in a peer-to-peer
network?

Sure, you can share any files and folders. The key is creating the same username in the remote computers. This how to may help,

A computer running Windows XP Professional sets up an administrative
share for each disk partition: C$, D$, etc.

You can right-click and share any desired folder(s).

I'm asking about Professional.  So, if I understand it correctly, any
administrator (or whoever I designate) on the p2p network has access to every
hard drive in the workgroup through C$, etc.  I can designate other users,
however, to only share what folders I explicitly give access to.  I can also
set up other shares for administrators for ease of use.

What does Home do?  Can it be part of a p2p network, along with Professional?

control access to shares on an XP Pro computer, disable simple file
sharing on that computer:

1. Open My Computer.
2. Click Tools > Folder Options > View.
3. Scroll to the end of the list of advanced settings.
4. Un-check the box "Use simple file sharing (Recommended)".

I'm assuming that simple file sharing is disabled on XP Pro in the
rest of my answers.

Only users who have an administrator account on an XP Pro computer can
access  administrative shares belonging to that XP Pro computer.  So,
if I'm an administrator on my computer, but I'm not an administrator
on your computer, I can't access your administrative shares.

You can't define permissions for administrative shares.  You can't
allow a non-administrator to access them.

You have full control over access to non-administrative shares.  Ron
Lowe and I have written a web page with details:

Windows XP Professional File Sharing

Home doesn't create administrative shares.  It lets you share desired
folders.  It doesn't let you disable simple file sharing.  It doesn't
let you define permissions on shared folders.  All users on all
computers can access its shared folders.

Home can access shared folders belonging to an XP Pro computer exactly
the same way that an XP Pro computer can.

Yes.  All versions of Windows released since the early 1990s can
network p2p with each other.
