Hi. I have a customer who lost connection from their Mac to a shared folder on a Win7 laptop in their office. The office is primarily Mac with this Win7 laptop. They need access to the Win7 laptop to import blood work. I cannot determine what is wrong and cannot ping the Win7 laptop from any Macs, but I can ping the Macs from the Win7 laptop. IPV6 is disabled, static IP and DHCP have both been tried, Win7 is wifi and Mac is on a wire, IPs are in the correct class, and subnets are correct (255.255.255.0), as are workgroup names.
I can see the Win7 in the network on the Macs, but cannot connect to the NetBios name either. I have cleared the keychain values, SMB is active, Win7 setup as a home network, firewall is turned off on both Mac and Windows, Authenticating user account with password is configured on Win7, Win7 allows 40 or 56bit encryption to connect, and set to allow user accounts and passwords to connect. I cannot determine at all why I cannot even ping this Win7 laptop from any Mac on the network. I have reboot the Win7 and Mac machines.
