I have a little home server running ubuntu that I've been using for 2 years to share files locally and store files. Recently the built-in NIC on the server's mobo died. So I purchased an NIC that plugs into a PCIe port. I popped it in, changed its name from eth1 to eth0, and edited my router preferences so it assigns it the same ip that it's always had.
Now when I go to access it from any of my windows computer it just won't connect and I get "windows cannot access \\myserver (error code 0x80070035 network path not found).
I am able to access it with my android tablet through ESfilebrowser with no problem at all.
I'm a little stumped since nothing really changed except the MAC address of eth0.
