In my nursing home I have 3 computers. One in my room, lets call it "PC A".
Second one belongs to my manager. Lets call it "PC B". Third one is in the
medical store. Lers call it "PC C". All run windows xp professional. PC B
had some windows error and was unable to boot into. So I had to reformat the
HDD and reinstalled windows XP professional. I created 3 user accounts on PC
B. One is my account which is an administrative account, the other two belong
to my manager and the radiologist doctor and they are limited accounts. I
have a local LAN there but I have never ever given internet access to these
PCs for security reasons. PCs C & A have already been connected and I can
access PC C from my PC PC A. Now remember PC B was formatted and windows XP
was reloaded. I made the "desktop folder" and the "my documents folder "
shared in PC B for all three accounts.

This is the setup. Now my problem is that I can access my desktop and my
documents folder on PC B through PC A, but I am unable to access the desktop
and documents folders of my manager and the radiologist doctor's documents &
desktop through PC A. Everytime I try to do that it says, "you do not have
the necessary priviledges to access. Pl contact the systen adminstrator." I
don't understand. I am the adminstrator in all the three pCs. I can access my
account in PC B, then why can't i access the other two accounts on PC B ? I
tried removing the log in password on the other two limited accounts on PC B,
but again the same message. I tried creating a new "trial acocunt" on PC B ,
but again the the same problem.

I am really stumped. Can somebody pl help me without asking me to reformat
the HDD AND RELOADING WINDOWS ?

PC A has win XP SP 2, PC C has Win XP SP2, but I loaded Win XP SP 3 on PC B
as I loaded windows again on PC B. Is that the problem ?

No. The problem is probably that you haven't created matching user
accounts/passwords and/or have misconfigured your firewall.

Problems sharing files between computers on a network are generally caused by
1) a misconfigured firewall or overlooked firewall (including a stateful
firewall in a VPN); 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.

A. 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/security program with its own firewall
component, 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. Refer to any third party
security program's Help or user forums for how to properly configure its
firewall. Do not run more than one firewall. DO NOT TURN OFF FIREWALLS;
CONFIGURE THEM CORRECTLY.

B. For ease of organization, put all computers in the same Workgroup. This
is done from the System applet in Control Panel, Computer Name tab.

C. Create matching user accounts and passwords on all machines. You do not
need to be logged into the same account on all machines and the passwords
assigned to each user account can be different; the accounts/passwords just
need to exist and match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS,
EVEN IF ONLY SIMPLE ONES.

D. If one or more of the computers is XP Pro or Media Center, turn off Simple
File Sharing (Folder Options>View tab).
