I have a Windows server 2008 with several Windows 7 desktops. All connect fine to the shared file on the server except one. It is connected physically and can ping the server, the router, etc. and can see all other computers / router / switches / printers except the server. It also does not have Internet access but all of the other workstations do. It has received a DHCP IP address as the others do and shows up in the router client list. All machines are on "Workgroup" and use the same first three sets of IP as 192.168.0.xxx. There is a user account on the server with the same name and password that the client PC is using and the shared folder lists that user account. We have tried restarting, IPConfig /renew and /release and /flushdns and registerdns. We are seeking some answers to this issue...thanks!
