Access Denied and Can't Take Ownership on Network Hard Drive

I have a network hard drive mapped as Z: which I have become unable to do ANYTHING with. I can't delete anything, change anything, or add anything to the drive. I just get that blasted "Destination folder access denied. You need permission to perform this action."

The internet has provided me with a plethora of solutions to this issue, and none of them have worked.

I'm logged on as administrator.

User Account Control is totally off.

Windows 7 will allow me to neither change permissions nor ownership of Z: or any folder or file within Z:.

I try giving Full Control to Everyone and it says "An error occurred while applying security information to (file name). Access is denied."

I go into Advanced and click the Owner tab. It states the current owner of everything on Z: is "nobody," and if I try to change the owner, it says "Unable to set new owner on Z:. Access is denied."

I've tried going into command prompt and changing ownership using "takeown /f Z:" and I just get "Z: Access is denied."

I've run out of ideas. Please help.

Not sure what you mean by "Server Side."

I just tried remapping the drive, that didn't work. I went under "Network" and clicked the name of the NAS listed under "Computer" and couldn't change any permissions that way either.

I went and downloaded and installed the "Take Ownership Shortcut" that I found here, and that didn't work either. A command prompt box blinks on the screen for half a second, and the folder is still listed as owned by "nobody."

It's a Maxtor Central Axis. I can't find any way to change permissions of the NAS itself, and, just out of curiosity, I fired up my old XP computer, but that one wouldn't let me write anything to the NAS either, so I'm guessing it IS an issue with the NAS.

Usually going into the Security tab of the drive itself and enabling permissions there will allow you access into that drive. You may need to add "Everyone" to the permissions list in the Security tab. After that you should be able to take ownership of the drive. You may need to install the drive back onto the machine it was created at first.
