Networking problem very friustrating. any help appreciated

I have a small home network connecting through a wrt54g v6 with the latest
firmware.

The network:
PC A (mine) is wired to the router. It is the only computer with a fixed IP
address, as I run a comms server for gaming. Running Windows XP
professional. There is an Epson printer on this PC
PC B (my wife's) is wired to the router. Dynamic IP, and also win xp prof.
There is a Brother laser printer connected.
Laptop C. Wireless connection, wep128, running win xp home edition.
Laptop D. Wireless connection, wep 128, running windows 2000 prof.

The problem:
All computers can access the internet for all applications with no problem.
All computers can see the others (A, B, C and D) in "Network
Neighbourhood/Computers near me" and can ping the other machines. All
computers have the other computers' logon and passwords in the Users list
with sharing permissions.
Computers B, C, and D can all share folders on each other, and C and D can
use the printer attached to B. Computer A can see and use the shared folders
on B, C and D, and can use the printer on B.
However, although B, C and D can see and ping A, when I try to connect to
any shared folders or the printer on A from any of the other computers, I
get the "Computer XXXX is inaccessible. You do not have the appropriate
permissions" message. This occurs whether or not the windows firewall is
enabled on any or all machines, and whether "use simple file sharing" is
checked or unchecked. The only things running in the network setup on each
machine are "client for MS windows", File and printer sharing, and TCP/IP.
So I can send files from A to B, C or D, and use the printer on B, but I
can't send files back to A from any machine, and cannot connect to the
printer on A from any machine.

I have deleted the users on A and added them back multiple times, so I'm
sure that the usernames and passwords are correct. I have tried PC A running
as a dynamic IP assigned by the router just to see what happens, and it's
the same problem.

This is really annoying me!! Can anyone help, please?

Check to see if "simple file sharing" is un-ticked under Windows Explorer -
Tools - Folder Options - View tab.
