Trying to network PC (Win XP Pro)and laptop (Win XP Home) using cable modem and switch. PC can ping laptop but not 127.0.0.1. Laptop can ping 127.0.0.1 but not PC. Subnet masks are both 255.255.255.0 and gateway is same for both. Cannot access files from either. Workgroup visible but not accessible. "You may not have permission to use this resource...The list of servers for this workgroup is not available." Also using Norton System Works and Firewall but allowed access for each IP under Access Rules.

Try creating the user of XP Pro as local user account in XP Home and create XP Home user as local account user in XP Pro. Assign a static IP address for each system, i.e, 192.168.0.1 and 192.168.0.2. If you have two computers, what list of servers you were referring to?

by margob

Both computers include the same user names as user accounts and none are password protected. Each has a different static IP address. The words I put in quotes in my question are the error message I get when I try to view my workgroup in Network Connections. I have no idea what it means by permissions required or servers listed. I've searched everywhere and am completely baffled!

Well if you cannot ping 127.0.0.1 (loop-back)on the desktop the your TCP/IP config on the desktop is flawed. reinstall TCP/IP on the desktop, check the subnet mask and ip address of the desktop.

I reinstalled TCP/IP on the desktop. The current IP address has a new lease from server. Still can't ping 127.0.0.1 but can still ping the laptop. Network Connections has Local Area Connection and 1394 as well as a Network Bridge. I removed bothfrom the bridge and disabled the bridge but still can't work. Should the bridge be enabled and,if so, which connection should be attached to the bridge? ICS is disabled and the Firewall is not enabled. Both computers have IP address as Trusted Sites in Norton's Firewall setting.

Removed all connections, reset the modem (again) and reconnected. Had to remove the Network Bridge Windows XP keeps putting in and now all 3 computers can see each other. Only problem left is how to get the laptop rights to open the files from the PC. Must be some security in XP that XP home can't open XP Professional files?? I can ping all the net view stuff in troubleshooting and can see the folders but can't open them. Logged in as administrator on both XP computers but have a feeling the laptop connection is called guest with admin rights. How can that be corrected?

Reinstalled the adapter and still nothing. Removed all wired and connected a router to the switch and now I can see another computer (running Windows ME) but can't access files and still can't see laptop running WIndows XP. Also can't ping the loop 127.0.0.1 but all 3 computers can ping each other. Still getting error messages about access rights and permission.

Comcast assigned different IP addresses to each of the computers that begin with 68.38. The DHCP server has 172.30.110.37 for all three. The Network bridge has 192.168.0.1 for all three. Should I change the IP address on the Network Bridge to be different consecutive numbers for each computer? Why can I see Windows ME from XP Pro but can't see the computer on XP home? Also can't understand why the main PC can't ping 127.0.0.1 but works fine otherwise on the internet. Should I be using a router instead of a switch?

by margob

Actually, I had no idea what pinging 127.0.0.1 meant! Someone suggested I try it along with pinging the other computers. Yes, the laptop is also running DCHP. We have been working on refurbishing other computers and keep adding and removing the computers from our router. We probably should have reset everything after each change. If I use the networking wizard it sets up a bridge connection and cannot network but can get to the internet. If I remove the bridge, I can see the other computers. All the computers can see one another now but can't access each others files, with sporadic exceptions.

Try removing the network adapter from the system and reinstalling. This worked several times even when I installed a wireless card in my notebook this was neccassay to get laptop and some pc's running on the network.

You didn't mention what IP addresses the 2 machines have. You say you are using a subnet mask of 255.255.255.0. If this is the case you must not use the IP range 192.168.0.x due to different class of network. Try 192.168.1.1 for the one PC and 192.168.1.2 for the other.

Hope this helps.

Realize that pinging 127.0.0.1 has nothing to do with any external hardware such as bridges and the like. I does not even anything to do with your network card! It only tests the correct installation of TCP/IP on your system. Is the laptop also running DCHP? Try entering a static IP address and see what happens when you ping 127.0.0.1
