I've tried 4.60.and 4.61

My client OS is windows 7 RC 7100, our AD is Windows 2000 SP4 with all current updates.

Same results when run normally or run as administrator.

The OS itself must be recognising my global group memberships as I can access shares etc.

I've tried several variations of script but basically doing a query for global group membership returns no and enumerating all group membership returns only domain local groups.

Script example:
if ingroup ("GG-ITS-Users")
? "Yes"
Else
? "No"
EndIf

Script example:
$Index = 0
DO
$Group = ENUMGROUP($Index)
$Index=$Index+1
? $Group
UNTIL Len($Group) = 0
get $anykey
