Won't discover other workgroup computers
I have a problem many people seem to have and I have spent many hours/days trying to fix it unsuccessfully. I have one Win-7 SP1 64-bit computer and several other Win-XP SP-3 32-bit computers on a gigabit home network with a Linksys RVS 4000 router. All computers have the same workgroup. All computers have internet access. All computers can ping the others and I can browse to the other computers by entering the IP address: \\192.168.blah.blah IP6 is DISABLED on the Win-7 machine. Netbios is ENABLED on all machines. Win-7 computer is set to Home Network and all Advanced Sharing Settings permissions are ON; Network Discovery, ON; File and Printer Sharing, ON; Public Folder Sharing, ON. Win-7 computer shows HomeGroup as Joined and will not let me leave the HomeGroup. Windows firewall on XP computers is disabled. Norton firewall is up, but it has always been up and I have tried disabling it with no change. Win-7 computer does not have Norton yet and I have not fooled with Security Essentials. I don't know exactly when it started happening, but: The computers do not show each other on the Windows Explorer Network page, In the Win-XP computers, only the folders that were added manually do show up. But there is no AUTOMATIC discovery. The XP computers all get an error if I try to access the workgroup from Network Neighborhood by exploring for computers, saying the Workgroup server is not available or I don't have access. The Win-7 network screen only shows the Win-7 computer itself and none of the XP computers. It also shows other network devices as it should, however. At times, although I can't replicate it right now, the XP computers will show the others, but won't show the Win-7 computer, if I go through the network connection set up wizard in IE8. If i reboot, the access seems to go away...but I cannot make them show up now. At times, but not now, I have been able to see all network computers on the Win-7 computer. I have tried everything I can find, including changing one networking key in the registry on the XP machines from an 8 to a 1. This worked for other people, but didn't change anything for me. Any suggestions would be appreciated.
