Firewall Windows 7 & scaning PC

Hello all.

I need help in configuring firewall windows 7 for scaning PC in domain windows.

Firewall off - scan is saccessful.

Firewall on and set open state for any port and any protocol from local area network - "No response received from workstation.  Probably the workstation might be switched off or does not exist".

Help me, give me, please, detailed instructions on configuring firewall and security policy!

Thanks.
