LAN problem

[ashok_inder]

I have a desktop and a laptop both running on windows xp with service pack 3 and connect with an ethernet wire.I can access files on my desktop through laptop but whenever I try to access files on my laptop through desktop then I immediately get an error stating that I have no access due to restriction,even though I have set file and printer sharing checked in the lan settings.
What is the reason for this problem.
I use comodo firewall as my firewall.

Hi,
Check the firewall settings of comodo firewall and set exclusion for your desktop's IP address so that firewall will allow desktop's IP for file transfer.
