How do I re-connect one of my PC's to he TrueNAS network

I am a recent user of the TrueNAS software and when I set up the system I connected 2 PC’s to the network. Some weeks later, one of the PC’s still connects without any difficulty, but the second (my main PC) no longer seems to be able to access the N drive. How can I re-connect this second PC.

Try deleting the N drive on the Windows machine, reboot and map the share again.

If that doesn’t work, post back with what version of TrueNAS your on.
