ABOU,

The ping attempts from your PC either by IP or hostname are troublesome. The pings from your LAPTOP seem to work fine and tell me that Internet connectivity and DNS lookups are fine on your laptop - but NOT on your PC.

Try temporarily disabling both Peer Guardian and NOD32 on the PC and perform those same tests. Also check if the original problem of not being able to see workgroup shares goes away. If disabling one or both of those programs on your PC fixes this problem - then something is not configured correctly in either Peer Guardian, NOD32 or both.

There should be settings in NOD32 that allow you to open up access to IPs on your local area network, i.e. 192.168.1.0. - or you specifically open up access to the 3 IPs on your LAN (PC, Laptop & Router). Also, if you know the physical addresses of your ISP's DNS servers, try hard coding these addresses into the PC's IP settings rather than using your router's address as a DNS server.

Also look at the WINS tab under the Advanced button under your TCP/IP settings within your Local Area Network connection. How are the Netbios related settings configured? Are you using a hosts or lmhosts file?

How is your router configured? Any special settings on your router in terms of security, NATS, triggering, etc?

Have you checked the NOD32 logs to see if any security events are being logged? This could prove helpful. Sorry for so many more questions - but sometimes this is the only way to solve issues like this.
