File sharing

I know this topic has come up repeatedly and I have tried almost
everything in every article and I am stumped. Please throw some
suggestions.

I have three computers running windows xp pro. Computer A is the
problem. Computers B and C seem to be okay. Heres what happens. B and
C can see each other and do file sharing. B and C can see A, but they
both get accessiblity error messages when they try to browse A. Computer
A can see and read and write to B and C. Computer A has two printers
that are shared, but B and C can't access them (they don't show up when I
try to add a network printer)

All computers are running simple file sharing behind a broadband router
so they all have private IP addresses. I have tried with the windows
firewall on and off. No other firewall software is being used.

I have CA antivirus and antispam running, but I have uninstalled and
tried.

All three shared computers have simple names like "chris" or "desktop"

This all used to work and that it stopped, but I'm not sure when because
I don't often print or file share from computer's B and C.

I have also connected other computers that I am troubleshooting for
people and they also can't access computer A, but they can always see it
in the workgroup computer list.

If you reply to my email remove the word "block", but I would prefer you
reply here.

Thanks in advance.

Try accessinig a shared folder on Computer A directly by typing this
line in the Start > Run box on one of the other computers:

\\computer\share

Substitute the actual computer and share names for Computer A.

If that works, the problem that you've seen is probably that a
registry entry that allows browsing the computer has the wrong value.
Run the registry editor (Start > Run > regedit) on Computer A and open
this key:

HLM\SYSTEM\CurrentControlSet\Control\LSA

Set the value of RestrictAnonymous to 0. Reboot and try accessing the
Computer A again.

Interestingly I had made this change before and it did not work, but I
subsequently had to repair the security settings because of errors when
opening the policy editor (another article was making recommendations).
After I repaired the security policy I never went back to change this
registry setting.

I changed the setting and it worked.

Thanks for the help.
