Network problem between 2 PCs

Hi!

I have setup network between 2 PCs using the cross-cabling. I have shared drive/folders on both PCs. The problem I’m facing is from PC1 I am able to access the files on PC 2. But from PC2 I can only see PC1 in the network, when I click on it, a prompt shows up saying PC2 is cannot be access contact the system admin etc.

On PC1 I’m running ZoneAlarm. Is it that restricting access to PC1 from PC2?

The IP addresses I have assigned on PC1: 192.168.0.1, PC2: 192.168.0.2

Please help. Thanks in advance.
