My employer has a network which primarily consists of Windows XP workstations; and I am a Linux user at home.
I have a single Windows 7 workstation which was moved and reconnected to the same switch port in the network closet. At this time, the previously-functioning workstation is listing the wired network connection as an Unidentified public network and not allowing the type of network to be changed.
One possible wrinkle is that the previous IT support staff has set static IP addresses in the 188.8.131.52/24 range (which is not RFC1918 compliant) behind a NAT firewall.
All of the Windows XP clients, Server 2003 servers, and Linux VMs will connect to the Internet without fail. However, this Windows 7 client is refusing to connect, even to the local default gateway.
I ensured the networking information was accurate, including the default gateway and DNS servers, and I have double-checked that the local firewalls are temporarily completely off.
I also noted that when I changed the IP address to a 192.168.1.0/24 address, the network type changed to Work, but that is not a permanent solution at this time.
What am I missing? What logic behind the Windows 7 networking would cause this? Is this primarily due to the IP addressing scheme used in my network?
