I have the following simple peer-to-peer (simple file sharing) Windows XP Pro network, with SP2 on all PCs:
All Pcs have 2 network cards (1-100 Mbps standard but unused and 1 Gbps which I use. Drivers for the 1Gbps cards of the 3 new computers have the latest version of their drivers.
PCs A and B were already installed and everything worked fine. I just installed The other 3 PCs and used the Network wizard to configure TCP-IP on them.
I gave the wizard the following options:
-Each PC connects to Internet through a gateway (the router)
-All 5 PCs have the same workgroup
All computers have the WinXP firewall with these options:
-File & printer sharing exception checked
-Allow incoming echo request
My router successfully assigned addresses to all PCs via DHCP.
I can use Internet Explorer without problems on all computers. However, THERE ARE MANY PROBLEMS:
-On PCs A & B (already there), I get all shared files on these 2 PCs in My Network Places, but no Shared Docs of any of the 3 new PCs
-On the same PCs I (finally) got all 5 PCs when I click on View Workgroup computers.
-On none of the 3 new PCs do I get any shared file in My Network Places (neither their own standard Shared Doc, nor any shared file of any computer)
-On none of the 3 new PCs can I get anything when I View Workgroup computers (I get an error message)
I made the following tests on one of the new computers:
-I pinged its own address: no success
-I pinged all other 4 computers from it: it succeeded only when pingin the 2 PCs that were already there
-I pinged my router with success
I tried to ping one of the new PCs from my one of my earlier PCs, without success.
I tried to disable the firewall on different PCs, but it did not solve any problem.
