drive sharing over lan - driving me nuts
ok here is scenario,
originally worked fine on a simple lan setup. between 2 windows 7 machines. same subnet ip range.
I then routed a static internet ip to this desktop machine and of course assigned new gateway to it. the other machine left on the old lan ip range as routing that over other internet connection. these machines are all still on same physical network.
I then added a lan ip to this machine as a second ip on the interface.
this got the other machine able to see this machine shared drives and am able to connect to other machine over remote desktop on lan ip. at this stage I assumed was all fixed.
noticed today I could not from this machine access shared drives on other machine so one way traffic. boh machines can ping each other fine of course.
so thought hmm maybe its because the net ip is first on the interface and lan 2nd so deleted both ip's and made sure lan ip added first, I thought bingo as I was able to access other machine again from this machine, but guess what. The other machine then couldnt see the drives on this machine, so I reversed the one way traffic.
I then played with netbios settings unsure of the role of netbios on modern file sharing and enabled ipv6 on this nic. Now both machines can access each others shared drives but ONLY if I manually know the machine name, here is what I mean. I have 2 explorer windows open on this machine, the first window has the other machine name already listed in left window as remembered it from earlier, so I can click on it there and see all shared drives. If I open a new window the machine doesnt show, and in addition if I click on network in the first window I dont see the other machine, so the drives are accessible but the machine doesnt show itself in the network window. Same on other machine, can access the drives on here but only if I manually type the network address in or have a window which has remembered the name on the left. In addition the machine randomly appears in the network window and then goes again.
This is where I am now.
So this machine
192.168.1.124 and <internet ip> assigned to nic.
192.168.1.125 assigned to other machine.
result dodgy file sharing.
