Windows 7 Main computer can not access other networked computers

[thewolfe]

I have 4 computers'

"Main" on Work - Network 5
"Spare" on Work - Network 2
"3rd comp" on Work - Network 2
"Laptop" on - Home network (wireless)

All networked computers can "see" all 4 computers EXCEPT Main can not access any of the other 3 computers.

Would it have anything to do with "Network 5" on the main being different that Network 2 on the other computers?

Also is there a way to wipe out all networked computers and start from scratch so there all on the same Home/Work network with the same number for the network.

I have had all my computer networked but somewhere along the line my main computer can't see the other ones. And from what I can tell the main computer has all the same sharing boxes ticked.

Is there a way to delete all sharing on all computers and start from scratch?

Thanks and Merry Christmas to you!
