Permission error (File sharing)

I have just created a workgroup between 2 computers and
wireless file sharing is working fine.
I can access folders which are on my main pc
from the second pc, but when i try to open
the contents of the folder, I get permission error.
I had make sure that when i select the folder to share
between workgroup i check both the options:
- share between workgroup
- allow users to edit the file
so what seems to be the problem here?
plz advice

it's probably your firewall. You might have to add your network address to the allow list. Every firewall is different. Which are you using?

well the main computer has Zonealarm security suite installed
and the second computer doesnt have anything installed
