a challenge for network geniuses

M

MajBach

Tried to make this as simple to follow as possible yet thorough.
Really appreciate the time you take to read.

2 PCs: a desktop and a laptop (computer names are the same for
simplicity here)Both XP Pro
The desktop is connected via USB to a DSL modem.
The laptop is connected to the desktop via Ethernet cable

Problem: cannot share files between the two after every conceivable
method of setting them up including network wizard, network ID name
changes, computer name changes, disabling firewall etc. Strange - had
them working once before but don't know what I have done to create
this problem.

Observations:
Both computers can easily surf the Internet, so, the laptop IS
communicating with the desktop. I set this up through the network
wizard.

The laptop 'sees' itself and the shared folders within it when I
select "view workgroup computers". The desktop computer does not see
itself. Neither computer 'sees' each other.

On the desktop:
'Network Connections', there are two: "USB Internet Shared" and
"Ethernet" (I named myself).
The TCP/IP Protocol Properties for USB Internet is "Obtain IP address
automatically"
For the Ethernet connection the TCP/IP is 192 168 0 1 and 255 255 255
0
Both have file and print sharing 'On'

On the Laptop under Network Connections
There is only the one: "Local area connection" and the TCP/IP is set
to "obtain Automatically"

When both PCs are powered on:
On the Desktop when I type: "ping desktop", it's successful with no
loss
When I type "ping laptop", "could not find host
When I type "ping 192 168 0 1", works fine, no loss
However
If I turn the LAPTOP off and type "ping 192.168.0.1", I get request
timed out

When on the laptop:
Everything is the same as above EXCEPT when I type "ping desktop", it
DOES in fact see the desktop.

Here's another weird thing:
If I am on the desktop and type \\desktop, it does see the folders I
have set to share but clicking on any of them says they "may be
inaccessible"
But when I try \\laptop, it says "the location cannot be reached

Conversely, when I am on the laptop and type \\laptop....everything is
good but when I type \\desktop, I get a long pause and finally 'the
network path was not found'

What do I do now?
Thanks in advance!
