Can not see other PCs in the Network

Hi,

I have three computers connected in my home network. I have an ADSL modem which is 192.168.0 network. This is connected to a Wirless netgear router in the 10.0.0.1 network. All the pcs have the 10.0.0.x Ip address range.

I can not browse other computers in the same network. how can i access the harddisk of other computers in the network. all the computers have the default gate way the same, all are in the same workgroup.

previously when i had only two computers and an ADSL modem , i used network using the small home and ofice network feature of windows XP. can any one please let me know how can i set up to see other computer’s HDD..with out making a bridge connection..

thanks heaps for your time
