With windows 2008 R2, you can use AD Recycle bin feature to restore object and its group membership without need of system state backup and booting the DC into DSRM mode. This saves lot of time as well as hardwork required to restore the object and group membership, but organization having large number of domain controller running on windows 2003 will take time to upgrade the DC OS to windows 2008 R2. Windows 2008 R2 is only available in x64 bit, so hardware have to be supportive before you can install x64 bit OS. Due to this constraint it is difficult to upgrade all the DC to 2008 R2 to take benefit of windows 2008 R2 AD Recycle bin feature.
