Small network problem - help please

A small home network of 3 XP computers on a ADSL router.
Want to file and printer share amongst them.

All 3 PC's can see each other and show in View Workgroup Computers.
One of the 3 computers however will not permit it's files or the attached
printer to be shared.
That PC can access files on the other 2 PC's but when they try to access
it's files an error message about permissions etc. & contact network
administrator occurs.

All 3 PC's are ok on web page access.

Any ideas?

TIA

err no - never needed to do before.

Security software is XP firewall and free Avast anti virus.

Thanks.

within Windows Firewall settings (Exceptions tab) check that file & printer
sharing is ticked.

I am not sure about Avast but if you search through its settings can you see
anything that refers to Trusted............if there is a section you need to
install the ip addresses of the other 2 computers into each computers
settings. Comp A has B & C ip address, Comp B has A & C and Comp C has A &
B's.

don't forget a reboot cures 'it still does not work'.
