A) The EVERYONE group should NEVEr be a local adminsitartor.
B) Admin shares require local admin privileges.
C) If a non-admin needs to connect to an admin share then a local admin account MUST be used to map that share.
D) A user cannot authenticate as two different users againstt he same computer unless one used the IP address for the second authntication
E) The answer ahs already been provided to you and is well documented in the KiXtart Manual under USE
Code:

$comp='workstation'
$user='username'
$pass='password'
use u: '\\'+$comp+'\c$$' /user:+$comp+'\'+$user /pass:$password

will map the admin share C$ as drive letter U: using the credentials 'username' with password 'password' of the computer 'workstation'.
F) Having identical admin usernames/passowrds on all computers is a BIG security risk. You might be better off implementing a domain model and assigning proper rights to users. Why do users need to connect to admin shares? Admin shares are for admin purposes and should not be misused for other things.

You might want to read up on basic computer/network security if you want to implement a safe computing environment.
