Determine Domain and username used to map a network drive

Question

Using Windows 7 Enterprise with SP1, but I'm hoping to get a generic answer that would apply to Windows XP/2003/2008/Vista/7.

From a command prompt, I execute a net use command to map the Z: drive to a share on another computer, but I don't use my current credentials, I specify a different domain and user to map the drive.

net use z: \\rd-pc2037\C_DRIVE password /user:rd-pc2037\Administrator

The command completes successfully. Now that the drive is mapped, how can I find what Domain and Username I used to successfully map the drive? I can't seem to find what I want with the net use command.

C:\Users\rdomarat>net use 
New connections will not be remembered.

Status       Local     Remote                    Network
---------------------------------------------------------------------------- 
OK           Z:        \\rd-pc2037\C_DRIVE       Microsoft Windows Network 
The command completed successfully.

C:\Users\rdomarat>net use Z: 
Local name        Z: 
Remote name       \\rd-pc2037\C_DRIVE 
Resource type     Disk 
Status            OK
# Opens           0
# Connections     1 
The command completed successfully.

Checking the properties of the share in Windows Explorer and looking at the security tab showed me what permissions different people would have, but I didn't see how which DOMAIN\User I had used. I searched through the registry with limited success as well.

Any thought?
