Cannot access a computer in a local network

[doe]

Hi,

I'm having a problem accessing another computer
in a local network. Both computers are on the
same workgroup, and connected to a Linksys router.
Both computers are logged in using the same username
and password.

From computer_A, I see both computers in network neighborhood.
I can get to the share on computer_A withough any problem.
But although I can ping computer_B, I get an access error
when I click on the name of this computer in network neighborhood.

From computer_B, I cannot even access the workgroup in Windows
Explorer. I get timeouts when pinging computer_A (The name gets
resolved to the IP address, but packets don't return).

I've checked eveything on computer_B -- ICF (off), client for
Microsoft Networks, File/printer sharing, server service,
workstation service, security policy, etc. -- but cannot figure out
what needs to be done. I've tried simple file sharing on Computer_A
as well as "not simple" (i.e., shared to specific users).

Please help. Thanks.

If you have the firewall turned on, then shut it off.

Do the computers have different names?
