Volume shadow copy services: VSCS
It is a new feature available only in 2003 flavor. Useful for taking online backup and access recent versions of files and folders.

SUS (Software Update Services):

It is a new feature of 2003. When our network client or servers wat their updates from internet, if internet is available to all the client machines whole network will be busying updating OS &software. This leads to network traffic
To overcome this problem we have to use a separate server configure as SUS, which is connected to Internet and obtains updates. Client machines instead of contacting Internet for updates contact the intranet SUS server for updates. This can be scheduled.

SUS software has to be downloaded from the internet and also I.I.S.

Implimenting SUS:

Install SUS in one of the member servers
On DC

Configuring client machines to contact SUS server for updates.

On DC
Open ADUC
Create an OU
Join the client machines to this OU
OU properties
Group policy
GPO name
