this just doesnt work ??? groups

Hi,
I've tried this on 2 different setups now and it just doesnt seem to work or Im missing something...
setup-
I have been added to a local global security global security group ( called mymebers ). A folder on a DC is given permissions to be accesses by domain local security group ( called whocanaccess ). I've added ( mymembers ) to ( whocanaccess ) with full permissions.
Now in the properties of ( whocanaccess ) I can see ( mymembers ) listed. If I go to the properties of ( mymembers ) I can see myself in the members tab and ( whocanaccess ) in the members of tab. So it looks right.
However when I go to a pc and try to access the folder Im denied, why? Am I missing something?
Hope the explaination makes sense
Help its the last thing Im stuck on

Trying to think if there is something else.... Brain ...not...working....before coffee...is ready....
I take it your logged on to the domain and not locally when you try and access the directory?
Have you had a look at the effective permissions of your user ID or the group you are using?
i.e.
Share Permission: Deny
NTFS Permission: Full Control
Result: Deny
FYI Miscrosoft recommends you only use one or the other for restricting access. and that tyou use NTFS permission for restricting access on NTFS volumes (obvious right?) and Share permissiong for Fat volumes (since NTFS will not work.
so on a typical share you wolud do the following
Share Permission : Everyone group = Full control
Ntfs permssions : IT group = full control
staff = read only
the result is the most restictive so IT cna do what ever they want and Staff can only read.
if you use both sahe and NTFS troulbshooting permssion issues sucks..... my company did this and it have become a nightmare for me to troubleshoot and unfortunately I can not change it
J/K
oooh and read the 290 book for the commands...lot of em there
or go to www.technet.com
have read the command but as I said the syntax doesnt make sense
if you use the -expand switch as well it shows groups user belongs to through group nesting.
CN= Users common name
DC= Domain
I've only managed to get dsget working if the user is in one of the builtin folders(like above CN=Users, which is the builtin Users folder)...... When I try and use dsget on a user in an OU that you have specifically created it keeps failing.... anyone got some ideas?
CCNA | CCNA:Security | CCNP | CCIP
JNCIA:JUNOS | JNCIA:EX | JNCIS:ENT | JNCIS:SEC
JNCIS:SP | JNCIP:SP
I do not understand regarding the NTFS and SHARED PERMISSION.
How do i know that READ / CHANGE / FULL CONTROL of shared permission? They are Least restrictive OR the most restrictive
as well as the NTFS permission (Full control / Modify / Read & Execute and so on....) which one is the most restrictive permission or least restrictive permission.
Thanks
