13. Once the installation finishes, the Exchange Management Console will open. You will be presented with a report informing you of which servers are currently unlicensed and how long they may remain so before their functionality is diminished. Click OK to dismiss this report. 14. You will then be presented with the Finalize Deployment checklist shown in Figure 2-12.

Michael Hotek I finally was going to be home for more than a couple of days straight and was looking forward to spending the day working on new projects on the lathe. But on my way through the house and to the woodshop, the phone rang. I didn t know the desperate caller, who was from an organization that I had never heard of. But a DBA from an organization that I had worked with a couple of years ago had given him my phone number. The organization had a big problem: A disk in its drive array had failed, and the person who swapped in a new drive unfortunately chose the wrong drive and caused the entire system to shut down with a completely unrecoverable redundant array of inexpensive disks (RAID) array. I was apparently the organization s last resort to try to fix a problem no one else had been able to solve. I ve spent almost two decades doing emergency disaster recovery for hundreds of organizations around the globe, with a pretty high success rate. Most of the projects involved working to recover production systems that I had never seen before. The damages were caused by nearly every disaster you could think of: flood, fire, tornado, hurricane, tsunami, lightning, earthquake, water immersion, explosives, bullets, every normal hardware failure imaginable, security breeches, and even end-user error. After a virtual private network (VPN) into the organization s system and a severalhour-long conference call to work through everything, we managed to reconstruct just about everything by using a combination of backups, data extracts to other systems, and Lumigent Technologies Log Explorer product. We could not recover a small amount of data that was damaged during an initial failed recovery operation, but the organization could manually reconstruct the data. About the time I was finishing up with this customer, an e-mail popped into my inbox, asking if I could help yet another organization. It seems its hosting provider had toasted the drive array on which its data was sitting. Even better, there were no backups for the database. For the hundredth time, I had to ask myself, when were people ever going to learn Having a functional, tested backup and restore strategy, and deploying that strategy correctly, is the most fundamental part of any database implementation. Thankfully, I typically don t get several of these calls daily and have even managed an entire month in the last decade when I didn t have to deal with one. But I would have really liked to have spent a nice, relaxing day at my lathe, creating something that didn t have to do with a computer

There might be times when the owner of a printer can no longer manage that printer and you need to take ownership. Taking ownership of a printer enables you to change administrative responsibility for it. By default, the user who installed the printer owns it. If that user can no longer administer the printer, you should take ownership of it for example, if the current owner leaves the company. This section describes which users can take ownership of a printer and then explains how to do it.

The benefit versus the security risk of different types of Internet access Applications and protocols, such as Web browsers using Hypertext Transfer Protocol (HTTP) or Hypertext Transfer Protocol Secure (HTTPS), can provide a great deal of benefit to an organization. Therefore, most organizations accept the risk of enabling this type of access to the Internet. However, many organizations do not see the benefits of enabling chat-room clients or peer-to-peer file-sharing applications, or of providing Internet access for users using the ICQ protocol. For these companies, the risk of enabling these types of access exceeds the benefit, so access to the Internet using these methods is denied. Ease of use versus the security of the system Systems that are the easiest to use are often also the least secure; the most secure systems, on the other hand, may be almost impossible to use or to administer. Balance the requirement for security with the need for usability. If getting Internet access is too difficult, many users won t even try, and the organization will lose the potential benefit, while other users will spend a lot of time trying to figure out how to get around your security restrictions. The cost of providing security versus risk of loss without security Implementing a completely secure solution can be very expensive, both in terms of money spent on purchasing and managing the security solution, and in terms of performance a highly secure system might provide much slower performance. If an organization is working with highly confidential or private information, this cost is required. For other organizations, the cost of providing an excessively high level of security may be higher than the actual loss if the security is breached.

Tests should be run against a test version of the database. They should not be run against your production database servers. Your test data should be of the same nature and size as the data in your production server. This includes tables, their relationships, their indexes, and their data. If, for example, you have a table with millions of rows, it is important to test your application against a similar table with the same number of rows. You should test a steady state of the database. This ensures that tests are all testing against a stationary target. They might run and change this steady state, but when they are rerun they should be rerun against the initial state of the database. This also helps you to compare results between tests. You should create an automated means to initialize your test database. Your tests should be easily executed and re-executed. Having this automation ensures that tests can easily set up and reinitialize the database, as required. Test data should not typically be an exact copy of your production data. Most databases store some sort of personal or confidential data, such as credit card information, user names and addresses, Social Security numbers, and so on. You should write a data extraction algorithm that either replaces this data with scrambled versions or removes it. Tools are available that can help you with this process.

When SSRS is installed with the default configuration, it is immediately ready to use for report deployment and report access by users. However, if you install a second instance of SSRS that needs to be configured separately, or if you need to set up an SSRS server farm,
