I am having problems connecting a machine that has previously worked on my network. Here's what has happened;
- I have three PC's
- Two of them are older and run Windows XP Pro and one is the new PC running Win7 Pro
- Machine A (Windows XP Pro) has been my "server" with all my files
- Machine B (Windows XP Pro) has been my "workhorse" design machine
- Machine C (Windows 7 Pro) is the new "workhorse" design machine
- All three machines have been on the network so that I can copy files from B to C as C is the new machine I will be working on from now on.
- I then moved my CAT5 cable to the second story of my house where the "server" (Machine A) would go from now on.
- I know the cable works as I plugged a laptop in and was able to browse other machines from upstairs.
- If I plug machine A in though, I can see connectivity on the lights but I cannot see this machine on the network.
I then plugged the other machine in (B) and it too was not seen on the network. I left it over the weekend and miraculously, it showed this morning.
Of course, I don't need B to be on the network but A as it is my file server but again, it is not online.
I am wondering if it is an IP address issue and how can I remotely release an IP address of a machine or is there a way of releasing an IP address on a specific port (plug) of the router?
