If you are using multiple SUS servers, you can perform a phased rollout. In a phased rollout, you first deploy updates to client computers of the parent SUS server. (These clients are typically computers on your test network.) After verifying that there are no issues with the updates, you then deploy updates to the client computers of the child SUS servers. To do this,

9 On the Networking Software page, you can choose to install additional networking software if needed. To gain full access to network resources, you need to select File And Printer Sharing For Microsoft Networks (if it is not enabled by default). Click Next and then click Finish.

disable synchronization of the approvals list on the child servers before approving the updates that you want to test. When you are ready to deploy the updates to the rest of the network, enable the synchronization of the approvals list on each child SUS server. More Info

For more information about creating test labs, see the Planning, Testing, and Piloting Deployment Projects of the Windows Server 2003 Deployment Kit at http: //www.microsoft.com/resources/documentation/WindowsServ/2003/all/deployguide/en-us /Default.asp.

Organizations that do not have the resources to create a dedicated test lab can still test software updates by deploying them selectively to computers that are representative of the computers on the network but which do not have mission-critical roles. To deploy software updates to a select group of computers for testing within a production network, use one of the following techniques:

Manually log in to the test computers and install the software updates by using Windows Update or Microsoft Update. Configure the test computers to automatically download and install updates by using Automatic Updates. Download the updates from the Windows Catalog on the Windows Update Web site, and selectively deploy them to the test computers by using the Software Installation and Maintenance feature of Group Policy or via login scripts. Use multiple SUS servers to perform a phased rollout, as discussed in the Creating a Test Lab section of this chapter. Use WUS or SMS to target the deployment of the software updates to the test computers without affecting the rest of the network.

Making the Incoming Connection Secure Even with a simple incoming connection, you can still require users to submit an encrypted password, which gives you a stronger level of security and helps ensure that someone doesn t dial your modem s number and try to break into your computer or private network. To configure this option, perform these steps:

The final phase of the software management process is the deploy phase. In this phase, you prepare to roll out the software updates you identified and tested previously, perform the deployment, and then check for missing or failed updates.

Before you begin the deployment of a software update, you should notify all affected users. One common method of doing this is by sending an e-mail to all users notifying them that their computers will be updated and instructing them what actions, if any, they must take. Tell

users to leave their computers on during the deployment window, which is typically overnight. Do not include any attachments in this e-mail, and if you want to provide links to additional information, instruct users to copy and paste the links into their Web browser to ensure that the links are not fraudulent. If possible, use a digital certificate to sign the e-mail, ensuring authenticity.

If you are using a server-based software update management application, such as SUS or SMS, you must prepare the servers before you can deploy updates. If you are using SUS or WUS, synchronize all SUS or WUS servers to ensure that updates are available on the local SUS or WUS servers. Perform this synchronization after-hours, if possible, to avoid consuming too much network bandwidth during business hours. If the updates are not available on the child servers at the scheduled deployment time, manually synchronize the servers. If you are using SMS to deploy software updates, prepare SMS for deployment by importing SMS packages from the test environment, assigning distribution points, staging updates on distribution points, and selecting deployment groups.
