I have 3 computers in a workgroup, all 3 are running windows XP pro. The
shared folders of this computer (A7v8x) cannot be accessed by the other two
computers though this computer can accessed the shared folders of the other
two computers.

Have checked the followings and all are ok:-
- computer browser services running.
- workstation and server services are also running
- shared folders setup.
- guest account is on
- restrictanonymous in registry set to 0
- local security policy for access this computer from local network included
everyone account

Some observation for this computer :-
unable to get connetted ifor the internet connection in the internet gateway
area (connection failed), however there is no problem surfing the internet
(via local area connection 6). Cannot locate the internet connection sharing
from the properties of the Advanced tab of the local area connection 6

Appreciate for help/advice to resolve the probelms.
Thanks.

I have just about the same trouble with my network. Another thin I've noticed
is that I can not ping the one computer from the other two, but have no
problem vice versa.
