If user is a member of two different security groups than which permission is applied? Means one group has full permission and other has read only which permission is applied,And if I want one user to give only read only permission without changing group membership how it will configure? Thanks Vijay

If one group is granted Full Control and other group is granted Read Only - effective permissions will be Full Control. If at least one group has granted some permissions, the effective permissions will be the same as granted.Consider to use Effective Permissions tab in Advanced Security window to determine effective permissions.http://www.sysadmins.lv
