Networking w/ File Share... Seems exclusive access, help!

Hi Experts!

I had tried to search this for hours, but every search term is vague
and English has too many synonyms and overloaded words that have
several definitions it was not possible to narrow further for me and I
am still left without and answer. Curious if anyone had seen the
following and/or has advice on how to do what my intent is?

Intent:
I turned an old laptop with Windows XP Pro into a file server for my
home network. I did not feel the need to buy a server edition upgrade
since my home network is small and should not require more than 10
concurrent connections.

Problem:
It seems only one computer is able to access the file shares
exclusively. "net use" returns successfully, but browsing the drive/
folder returns an error.

The setup:
Let's narrow to 3 computers for simplicity, actually I have four
laptops and one MCE PC.

1 server, let's call it HOMER
1 MCE PC, let's call it BART
1 laptop, let's call it LISA

Network setup ( I doubt this matters, since the computers can all be
seen by each other):
HOMER is connected by CAT5e to a gigabit switch port
BART is also connected by CAT5e to adjacent gigabit switch port as
HOMER
gigabit switch is connected by CAT5e to Linksys WiFi router
LISA is connected by CAT5e to Linksys WiFi router
Linksys WiFi router is connected by CAT5e to cable modem


On HOMER I have:
A) Enabled File Sharing, and not simple file sharing
B) Created two user accounts with passwords (bartaccess and
lisaaccess)
C) Connected a TR4U USB enclosure, which holds 4 hard drives
D) Shared the root of the 4 external hard drives
E) Allowed the permissions to give bartaccess and lisaaccess full r/w/
e permissions
F) Disabled suspend/hibernate
G) Static IP address in the 192.168.1.xx range
H) Firewall is OFF
I) No Antivirus installed or running

I am able to access it and file shares from BART successfully by
doing:
start -> run -> cmd /u <ENTER>
net use \\IP.Dotted.Addr.Here /USER:bartaccess@HOMER password
Result: The command completed successfully.
explorer \\IP.Dotted.Addr.Here
Result: I can see all the 4 shares in explorer and click on them to
navigate
Back to cmd prompt
net use
Result: I can see the shared connections active

Meanwhile on LISA I do (without altering any network state from
above):
start -> run -> cmd /u <ENTER>
net use \\IP.Dotted.Addr.Here /USER:lisaaccess@HOMER password (I tried
bartaccess also)
Result: The command completed successfully.
explorer \\IP.Dotted.Addr.Here
Result: I can see all the 4 shares in explorer
HOWEVER, when I click on any of them to navigate I get this windows
error in a message box

---------------------------
IP.Dotted.Addr.Here
---------------------------
\\IP.Dotted.Addr.Here\DRIVE_1 is not accessible. You might not have
permission to use this network resource. Contact the administrator of
this server to find out if you have access permissions.

Access is denied.

---------------------------
OK
---------------------------

I am SURE I have access permissions and have not mistyped the
password. I had rechecked the share and it had maximum connections and
lisaaccess and bartaccess users allowed for the r/w/e permissions. I
tried with net use /delete about twenty times to make sure. Even going
back to BART I am able to access the folders. On LISA I have tried
doing a map networked drive with the login credentials and also run
into similar problems.

On HOMER:
I type netstat /a in a command prompt and see fewer than 10
connections active. I do not believe I am up against WinXP Pro limit
of connections. Any advice on knowing for sure would be appreciated, I
believe the error on LISA would indicate a maxed out connection than
the permission error.

Main question in lieu of any comments or suggestions to try in the
above steps:
Is there some concurrency limit for sharing USB connected storage at
root with full r/w/e permissions to multiple users over a network? I
would think no, but I am left unable to explain why I get the
permission error as shown above. At work many people are able to
connect into my dropbox at the same time, so I think it must be some
setting I have missed. And I don't know what the setting is and
whether it needs to take place on HOMER or LISA. I tried everything I
was able to think of, so now I am turning to the bigger brains. Thank
you in advance!

Hi
Make a shared folder on the server C:\ drive and see if then you can access
it from both client computers.
Try Mapping Drives (easy and faster access) instead of the Net use approach.
In general., make sure that the Software Firewall on each computer allows
free local traffic. If you use 3rd party Firewall On, Vista/XP Native
Firewall should be Off, and the active Firewall has to adjusted to your
Network IP numbers on what is some time called the Trusted Zone (consult
your 3rd Party Firewall instructions.

You also should know that when it means "concurrent" connections, it
does not mean up to ten other PCs can access. One PC can access / use
all the 10 concurrent "accesses."

Going to reply to my own post to thank Jack and smlunatick, fill in
other details, and let you know my solution in case anyone else comes
across it.

First off, thank you Jack. I was able to get it working without
invoking any tests on the C:\ drive. I'll update that later.

Also, thank you smlunatick. I understood the 10 concurrent connections
as being real connections and not different PC. I did a netstat /a to
determine the quantity of connections and verified it was below 10.

Other details:
HOMER and all other computers were on 'WORKGROUP'

My solution:

I tried various combo of the net use /USER command. The one that
worked for me was
net use \\IP.Dotted.Addr.Here /USER:HOMER\bartaccess password
Also worked with lisaaccess...

So this and similar did NOT work:
net use \\IP.Dotted.Addr.Here /USER:lisaaccess@HOMER password

I would chalk this up to some funniness involved with domain name
lookups. HOMER is connected to my router and gets a dynamic IP
address. But when I drop to command prompt and simply do nslookup
HOMER it fetches an IP address that does not match my public IP
address or internal IP Address. net use with /USER:domain\user must
skip the nslookup step? Not too sure and not sure if I care until it
breaks again :D
