I am attempting to map a couple of drives if a user is in the right AD group, this is my script

IF INGROUP("GROUP-NAME")
use O: "\\servername\foldername" /PERSISTENT:NO
use T: "\\servername\anotherfoldername" /PERSISTENT:NO
ENDIF

I have checked and I am in the AD group. I have tried adding the domain name in front of the group name but the application log is recording

Event Type: Error
Event Source: KIXTART
Event Category: None
Event ID: 1332

Description:
The description for Event ID ( 1332 ) in Source ( KIXTART ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: Failed to resolve SID(s) Error : No mapping between account names and security IDs was done. (0x534/1332).

When I run this code
use "O:" "\\berfsho001\ablage"
use "T:" "\\berfsho001\akten"
the drives map.
