I added the correct statement:

use m: "\\SCOOBY\DISC$$" ;thx sunnie4747

In the first IF statement and changed the rest also, as a result the rest of the if statements functioned properly after the first one was fixed. Hardcore programmers may want to take note of this preprocessor condition.

break on
;Get Home Directory

Use H: "\\SCOOBY\" + @USERID + "$"

;Get Standard Drives

Use I: \\SCOOBY\Public
Use J: \\SCOOBY\APPS

;Group Areas

IF @USERID = "Administrator"
use m: "\\SCOOBY\DISC$$"
ENDIF

IF INGROUP( "DOMAIN USERS" ) = 2
USE n: "\\SCOOBY\DISC$$"
ENDIF

$V = "@userid"
? $V
$X = "Administrator"
? $X
IF $V = $X
Use K: "\\SCOOBY\DISC$$"
ENDIF

IF "Administrator" = "Administrator"
use l: "\\SCOOBY\DISC$$"
ENDIF

This maybe the root of your second problem i read before above. Just make sure all syntax is correct up until the problem point.
