Cannot see other workgroup computers

Question

I have an external broadband modem connected to a tower PC (PC1) which in turn is connected to a network hub.  I have 2 laptops also connected to the hub. All computers are using Windows XP SP2.  PC1 was set up on the network using Network Wizard and shares it's internet connection with the rest of the network (a workgroup network called MSHOME).  Laptop1 (also set up with network wizard) can see PC1 under the MSHOME workgroup and can also connect to internet and use file and print sharing.  PC1 can also see Laptop1 and share files.  However Laptop2 (also in MSHOME workgroup) is unable to see PC1 or Laptop1 under MSHOME.  and PC1 and Laptop1 cannot see Laptop2 under MSHOME.  I have been trying to set up Laptop2 using network wizard also but with no success. Can anyone please help?  My poor brain hurts!

do you have a firewall?

Are these firewalls properly configured to allow local network traffic?   Steve

Yes I do.  PC1 is using NAV 2005's firewall while Laptop1 is using Windows firewall.  Both are enabled.  I plan to use Windows firewall on Laptop2 if i can get it on to this network.  Suppose I'd better say that it is a fully wired network.

What you have to do is figure out what range of ip addresses you have. i.e. 192.168.1.100-192.168.1.109 and set those up through the firewall as allowed ip's.
