    Hi there,

    First time poster and networking novice so please be gentle!

    I run a small business from home. My files are stored on a Seagate BlackArmor NAS, which has been working fine for 2+years. On Friday I was doing a manual backup and it froze. Despite rebooting it (and my computer) several times, I've been unable to map a drive to it. I have a wireless network.

    I'm getting the error message "An error occureed while reconnecting to Z: to xx.x.x.xxx Microsoft Windows Network. The local device name is already in use. This connection has not been restored."

    After doing some research, I've use cmd / net use to check all drives. Currently it's saying "There are no entries" on the list, so it doesn't appear Z (or any other letter) is in use. I've turned off Norton Smart Firewall and Intrustion Prevention.

    When I've tried to map the drive, despite it not showing up in Windows Explorer, it can make the folders on the drive appear using cmd / dir Z: command. Further, because it's a BlackArmor, I can access the files and folders remotely over the internet, so the drive doesn't appear to be damaged. For whatever reason, I just can't map to it.

    My SysInfo is below. Despite me mentioning cmd stuff above, please know that I'm still a novice and that's about as far as my knowledge extends. Thanks in advance for your help.
