I got a similar problem like Sonycea, this my scenario, I have just acquired a IBM Laptop R60e, a very recent model, the problem is I cannot communicate with the Laptop on a simple network, I have set all the IP addresses e.g the laptop is 192.168.0.x with subnet mask 255.255.255.0 other PC's have also corresponding IP addresses, the workgroup is the same. I can ping other PCs from my laptop but I cannot ping my laptop from other PC's on the workgroup. The laptop has networks speed of up to 1 Gb/s. Please F1 me :confused: ASAP!
