PC can't access shares on another PC

[Guest]

My laptop can no longer access shared files and a printer on my first
desktop, but the desktop CAN access shared files on the laptop.

And yet, the laptop can access shared files on my second desktop, and that
second desktop can also access them on the problem desktop. This really
starting to baffle me.

To summarize, how can A access files on C, but not on B, when B can access A,
and access C, and C can access A and access B? Obviously file sharing and
network connectivity are working on A and B, B just doesn't like A. If I
browse from B to A under Add a Network Place, I can see B but can't open it,
it won't show any shares under it. If I browse the same way from B, I can
reach A without a hitch.

Sometimes A gives me a message about not having permission to access this
resource on B. What permission is this? I've thrown everything on the B
share wide open, giving the share I want Full Control to the Everyone group
in both Share and NTFS permissions. That doesn't help. What other
permissions are there?

I also can't get to the printer on B either, but C can.

Anyone have any ideas?

Which machines are XP Pro and which are XP Home?
Networking works a bit differently between the two.

John, I accidently restarted this thread with more info. Here's the added
paragraph.
It is Windows XP SP2.

I just discovered that the ordinary
user account I set up for my wife CAN do all of the networking functions its
supposed to. My account, a member of the Adminstrators group cannot. The
built-in Adminstrator account doesn't network correctly either when I logon
on with it under Safe Mode. When I made a brand new account as a member of
the Adminstrator group, same problem. When I made new account that was user
only, it worked fine. So the problem seems to be isolated in Adminstrator
status. Could this be some kind of SID corruption?

You still haven't told me which machines are XP Home and which are XP
Pro. Assuming XP Pro, see if any of this makes sense:

When you try to connect to another machine and that other machine has a
user account on it with the same name and password as the connecting
machine, then everything is fine and it connects.

If a user with the same name exists on the client machine but the
passwords do not match, then access is denied.

If a user with the same name does not exist on the client machine, then
it attempts to connect as "Guest" user which may/may not work depending
on whether the guest account is enabled and what privileges have been
assigned to the target file/directory.

Try connecting using the command-line interface and the "net use"
command and see what errors you get:
net use * \\computername\sharename /user:computername\username

HTH,

John,

All three of my PCs are running Windows XP Pro SP2. I tried your
suggestion, it says "System error 67 has occurred.", followed by "The network
name cannot be found."

Yes, both machines have an account named Leon, both with the same password.
This used to work just fine, I can't figure out what changed.

Yet more weirdness, my old MAC laptop just connected to the "unresponsive"
PC without a hitch.

Since that makes both another PC and a MAC connecting just fine, I am right
in assuming that the problem is on the machine that can't make the
connection?

John,

Whoops, sorry I had left out the space after the *. It just connected, and
now everything works. Did this purge or reset something? Anyway, thank you
very much, this is a big help.

John,

The command below works great for restoring connectivity, but I lose it
again after rebooting. The command (now in a convient little batch file)
restores it again. But something's still wrong for this to be happening.
Any other ideas? I really appreciate the workaround, but if possible I'd
still like to understand the process. -Thanks
