Network drive found but not found?

Hi I'm having a problem that is causing me to pull my hair out. I hope someone can help. I'm using a Vernatim media share 1 tb network drive on my LAN to store things like my iTunes library. Well yesterday it started not allowing me to login through windows. I deleted the mapped share and tried to redo the connection and this seems to work. Only thing is when it finds the share and then the folder that I want to map it gives an error that it cannot be found. I'm looking right at the folder and drive and it still will not connect. Gives an error code 0x80070045 and tells me to check the name. The drive was lost to all windows 7 computers about the same time. I can ping it, log into it through the web interface view the media through windows media player when I click on the media share in the network window. I just cannot connect explorer to the drive to read or write to the drive. Am I missing something simple? Thanks.

Sorry it's Ethernet network share plugged directly into my Cisco e2000 router. My windows clients are a combination of wired and wireless.

I hadn't thought to try that I will have to give that a try. Another thing is if I log into admin panel through my web browser and explore the drive that way I get another error server resource not found. I'm logged in and can stream the media with WMP but it's like the directory structure doesn't exist. As I have been unable to find any kind of documentation or troubleshooting for this device online I am willing to try anything. I will swap router ports and cat5 when I get home.

Ok so switching cables and ports on the router had no effect at all. The error reported is 0x80070035 I think I had it wrong in the first post.

I am using Windows Firewall managed by norton 360. On a side note I was able to fix it,k although not how I had wanted to by formating the drive. It seems like a power outage or something had corrupted the index of the drive and since there is little to no documentation on this device online and customer service for the company is almost non existant I just did a reformat and all is well now.
