Windows – Cannot map network drives using ‘net use’ while elevated as an administrator

So, this problem stems from not being able to save anything on my network drives. I tried using takeown on everything in the network drive as the user Joey (which is an administrator on my computer because it's the only user account and it says so in the control panel, right?), so I decided to run cmd.exe as an administrator. Now it can't find the network drive to cd to, so I looked that up and found that it has to be mapped as an administrator.

net use f: \\joey-laptop\users\joey\my documents\folder is the command I'm using, and it gives me this output:

    Microsoft Windows [Version 6.1.7601]
    Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

    C:\Users\Joey>cd /DF:\
    The system cannot find the path specified.

    C:\Users\Joey>net use f: \\joey-laptop\user\joey\my documents\folder\
    The syntax of this command is:

    NET USE
    [devicename | *] [\\computername\sharename[\volume] [password | *]]
            [/USER:[domainname\]username]
            [/USER:[dotted domain name\]username]
            [/USER:[username@dotted domain name]
            [/SMARTCARD]
            [/SAVECRED]
            [[/DELETE] | [/PERSISTENT:{YES | NO}]]

    NET USE {devicename | *} [password | *] /HOME

    NET USE [/PERSISTENT:{YES | NO}]


    C:\Users\Joey>

I don't really know why it's giving me the help info, but it is, so I'm assuming it would be doing this regardless of the folder I was trying to map to. What am I doing wrong?

EDIT: F:\ is already mapped, but that was done as Joey. I read that net use lets you overwrite existing maps.

EDIT 2: Access denied when writing files to network drive is somewhat of a follow-up question to this.
