Can only ping one way

Hi

Not sure if this is a question for experts exchange, but I'm stuck and I need an expert.
As you're going to quickly realise I have precisely no idea about networking or hardware.  

I am trying to set up a home network between my main PC and my wireless laptop for.  Both are running Windows XP. The wireless internet network is up and running, but I'd like to share files and my printer between the two.

I've followed all the instructions and used the wizard, but it's not working.  I used the troubleshooter and have determined that I can ping from the PC to the laptop, but not the other way.

Is anyone available to help talk me through the process please?

Turn your XP firewall off and try pinging again

Thanks guys.

leegclystvale:  Okay turned off my firewall and that now pings the PC.  Progress.

But I can't leave the firewall off permanently, so what do I do now?  I guess I have to just allow my laptop's IP through it do I?  But I don't have a fixed IP.

Your router should be providing the firewall but you can turn it on and ensure that file and print sharing is added as an exception.  http://www.sophos.com/support/knowledgebase/article/11738.html
You shoul also ensure that you have file and print sharing enabled on the PC or laptop
To turn Simple File Sharing on or off in Windows XP Professional, follow these steps: 1. Double-click My Computer on the desktop. 2. On the Tools menu, click Folder Options. 3. Click the View tab, and then select the Use Simple File Sharing (Recommended) check box to turn on Simple File Sharing. (Clear this check box to turn off this feature.)

Hi

Okay I have checked that Simple File Sharing is on, which it is on both.

I have shared a folder on my PC, and when I look in network places on my laptop I can see a shortcut to it, but nothing happens when I click on it.
