My simple home network of 2 PCs with XP, SP3 and a Netgear WNDR3700 router was working great. I changed ISPs and now cannot get the home network back up. Running the home network wizard on each PC sets up internal IPs of 192.168.1.1 for the router and 192.168.1.2 and 192.168.1.3 for the 2 PCs. Shared folders and files appear to be set up correctly and I can successfully ping the router and the other PC from each PC. Following Microsoft's troubleshooting procedure, everything is good until I get to the step where the 'computername' is to appear in the shared folders list, in computer management, system tools, shared folders, shares. All other shared folders and devices appear correctly on each PC. This is just about the last step in the troubleshooting procedure, but I can't get past it. What can I do? Or is something else wrong? I'm almost to the point in thinking there is something in the registry (added with my ISP change process) that is preventing this from working.

HiMaybe this can Help.Make sure that the Software Firewall on each computer allows free local traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should be Off, and the active Firewall has to adjusted to your Network IP numbers on what is some time called the Trusted Zone (consult your 3rd Party Firewall instructionsGeneral example, http://www.ezlan.net/faq#trustedPlease Note that some 3rd party Software Firewalls keep blocking aspects of Local Traffic even it they are turned Off (disabled). If possible configure the Firewall correctly, or totally uninstall it to allow clean flow of local network traffic. If the 3rd party software is uninstalled or disables, make sure that Windows native Firewall is On .Windows XP File Sharing - http://support.microsoft.com/default.aspx?scid=kb;en-us;304040Printer Sharing XP - http://www.microsoft.com/windowsxp/using/networking/expert/honeycutt_july2.mspxWindows Native Firewall setting for Sharing XP -http://support.microsoft.com/kb/875357In Win XP pro you can Visually see the Permission/Security setting, and configure them to your liking.http://www.microsoft.com/windowsxp/using/security/learnmore/accesscontrol.mspx#securityTabWhen finished with the setting of the system it is advisable to Reboot all the hardware including the Router and all computers involved.Jack - Microsoft MVP, Windows Networking.

Typically, this is due to a firewall, in which case Jack's advice will help. In addition, there is a [rare] condition where the Node Type of a computer becomes set to "Peer-Peer" or "P-P" that will stop communication between computers. Bring up a command prompt (Start -> Run -> "cmd") and enter the command: ipconfig /allIf the "Node Type" line shows up as "Peer-Peer" or "P-P" or "P-type", ("Broadcast", "Mixed", and "Hybrid" are OK) then see the following KB article:"You cannot view other workgroup computers on the network on a Windows XP-based computer" < http://support.microsoft.com/kb/903267 >HTH, JW
