JwsclToken

Returns true if the user is a member of the administrators group; otherwise false.

JwIsMemberOfAdministratorsGroup checks if the user is a direct member of the Administrators group and this group is enabled for access checking. Therefore if this group has the flag use-for-deny-only the returned value is false. This usually happens if the user is an Administrator in Windows Vista with activated UAC. 

This function uses the Windows API function CheckTokenMembership and thus only checks whether the user is a member of the administrator group. However it does not check if the user belongs to a group that is a member of the administrators group. 

If you just intend to check for any administrator use JwCheckAdministratorAccess instead.
