I've read all that time and my ability will permit about the MS .NET
Framework, but I still don't understand it and I don't find answers to
my problems.
I had to install MS.NET when an upgrade to my ATI display driver
required it. Before installing this software I had the usual set of
'user folders' defined in my Win XP system, in 'Documents & Settings':
Administrator
All Users
<user defined>
and
Default User (hidden folder)
But after installation of .NET I have these ADDITIONAL folders in
Documents & Settings:
All Users.WINDOWS
<user defined>.<computer name>
Default User.WINDOWS (hidden)
Local Service (hidden)
Local Service.NT AUTHORITY (hidden)
Network Service (hidden)
Network Service.NT AUTHORITY (hidden)
Moreover most of the updates and temporary data are held in sub-folders
within the <user defined>.<computer name> folder, access to which by any
other computer on my home network is denied.
What re the additional folder for?
Which, if any, out of the total list of folders can I delete without
loss of function?
Why can I now not access the documents held by user <user defined>
using other computers on my network?
All of those folders were there already.They may have been hidden or you
may not have noticed them. I have no way of knowing. They are system
folders. Leave them alone and don't worry about them. As for your last
question, I don't know but not being able to do file/printer sharing has
nothing to do with installing .Net. Something has changed in your
networking setup. Below please find a general explanation of XP's
file/user hierarchy and general networking troubleshooting steps. These
are general "boilerplate" and not everything may be applicable to you.
Take the bits that are.
A. File/User Hierarchy
XP is a multi-user operating system, no matter if only one person is
using it. In all multi-user operating systems - NT, Win2k, XP, Unix,
Linux, Mac OSX - there is the one built-in account that is "god" on the
system. In Windows terminology, that is "Administrator". In the *nix
world, it is "root". This is a necessary account and is not normally
used in everyday work. You cannot delete the built-in Administrator
account nor would you ever want to.
Here is the explanation of what you really have:
My Computer - represents your entire computer, showing drives and shared
folders. Shared Folders are folders where you can put files you wish to
share with other users on the system. You don't need to use these
folders if you don't want to, but leave them alone!
[some name] C:\ - your first hard drive, usually the system drive.
Document and Settings - The "container" for all user settings. Each user
will have [username] Documents, Music, Videos, My Pictures.
Administrator - Built-in account - Leave alone! Do not use! Do not worry
about it!
All Users - Section where items common to all users go. In a multi-user
operating system, users have separate accounts. This is the place where
if you want to share files with all the other users on the system you
would put those files. You don't ever have to use those folders but they
need to be there. This is where programs you install that are meant to
be installed for all users put settings. All the "Shared Documents" type
of folders you see at the root of C:\ are shortcuts to the shared
folders in here. Leave them alone!
Default Users - This is the template from which new user accounts are
made. You will never put anything in any of those folders but they are
needed to create new users. In Linux we use "skel" ("skeleton" - get
it?). In Windows, the less-colorful term "Default User" is used. Leave
it alone!
[OEM] Administrator or Owner - This is the generic user created by the
OEM when installing the operating system. After all, the OEM doesn't
know who is going to buy the computer. If you aren't using this OEM user
account, you can delete it from the User Accounts applet in Control
Panel. It is not the same account as "Administrator".
My Network Places - This is a graphical representation of other
computers on the network and any shared network resources. If you don't
have other computers, you can remove the Network Places icon from the
Desktop using the Control Panel Display>Desktop>Customize Desktop
function. Leave the folder alone!
B. Networking
Problems sharing files between computers on a network are generally
caused by 1) a misconfigured firewall; or 2) inadvertently running two
firewalls such as the built-in Windows Firewall and a third-party
firewall; and/or 3) not having identical user accounts and passwords on
all Workgroup machines; 4) trying to create shares where the operating
system does not permit it.
Here are some general networking tips for home/small networks:
1. Configure firewalls on all machines to allow the Local Area Network
(LAN) traffic as trusted. With Windows Firewall, this means allowing
File/Printer Sharing on the Exceptions tab. Normally running the Network
Setup Wizard on XP will take care of this for those machines.The only
"gotcha" is that this will turn on the XPSP2 Windows Firewall. If you
aren't running a third-party firewall or have an antivirus with
"Internet Worm Protection" (like Norton 2006/07) which acts as a
firewall, then you're fine. With third-party firewalls, I usually
configure the LAN allowance with an IP range. Ex. would be
192.168.1.0-192.168.1.254. Obviously you would substitute your correct
subnet. Do not run more than one firewall.
2. With earlier Microsoft operating systems, the name of the Workgroup
didn't matter. Apparently it does with Vista, so put all computers in
the same Workgroup. This is done from the System applet in Control
Panel, Computer Name tab.
3. Create identical user accounts and passwords on all machines. If you
wish a machine to boot directly to the Desktop (into one particular
user's account) for convenience, you can do this. The instructions at
this link work for both XP and Vista:

4. If one or more of the computers is XP Pro or Media Center:
a. If you need Pro's ability to set fine-grained permissions, turn off
Simple File Sharing (Folder Options>View tab) and create identical user
accounts/passwords on all computers.
b. If you don't care about using Pro's advanced features, leave the
Simple File Sharing enabled.
Simple File Sharing means that Guest (network) is enabled. This means
that anyone without a user account on the target system can use its
resources. This is a security hole but only you can decide if it matters
in your situation.
I think it is a good idea to create the identical user
accounts/passwords in any case when Vista machines are involved and it
isn't an onerous task with home/small networks.
5. Create shares as desired. XP Home does not permit sharing of users'
home directories (My Documents) or Program Files, but you can share
folders inside those directories. A better choice is to simply use the
Shared Documents folder.
