NEW FEATURES IN SP3a
(contributed by Brian Moran, news editor, firstname.lastname@example.org)
All SQL Server 2000 customers should have upgraded their production systems to Service Pack 3 (SP3) by now for protection against the Slammer worm and other security vulnerabilities. But Microsoft recently released SP3a without much fanfare. What does SP3a address and who needs to upgrade to it? Microsoft's original Web page describing SP3a didn't specify what new features the service pack included or whether you needed to apply SP3a if you were already using SP3. However, Microsoft has now provided clearer answers to these questions on the SP3a download site.
SP3a replaces SP3, which is no longer available from Microsoft. You can download SP3a at http://www.microsoft.com/sql/downloads/2000/sp3.asp. If you haven't already installed SP3, you should upgrade to SP3a, but Microsoft says that no serious security problems require you to deploy SP3a if you're already using SP3.
The SP3a download site is still a bit confusing, implying that some features available in SP3 are brand-new in SP3a. Microsoft says that only three features are new in SP3a: SP3a lets you apply service-pack upgrades to SQL Server 2000 Evaluation Edition, contains a new version of Microsoft Data Access Components (MDAC), and disables listening on port 1434 when networking is disabled. The other features listed under "Benefits" on the download site were already released in SP3. (To read about the problems that the new MDAC version solves, see the Microsoft articles "FIX: SQL Server Does Not Start and an Access Violation Occurs After You Install SQL Server 2000 Service Pack 3," http://support.microsoft.com/?kbid=814572, and "FIX-Performance Degradation and Memory Leak in the SQL Server ODBC Driver," http://support.microsoft.com/?kbid=814410.)
Figuring out which service-pack version you're running—SP3 or SP3a—can be confusing. The downloadable files for SP3a and SP3 have the same names, the build numbers for both packs are the same in most cases, and ServerProperty('ProductLevel') reports "SP3" for both versions. However, you can distinguish between versions by looking at the version number of the Net-Library file ssnetlib.dll. The readme.txt file for SP3a says that this file's version number will be 2000.80.760.0 for SP3 and 2000.80.766.0 for SP3a. I hope Microsoft makes it easier to tell service-pack versions apart in the future.
ALERT: "How a Hacker Launches a SQL Injection Attack Step-by-Step" It's as simple as placing additional SQL commands into a Web Form input box giving hackers complete access to all your backend systems! Firewalls and IDS will not stop such attacks because SQL Injections are NOT seen as intruders. Download this *FREE* white paper from SPI Dynamics for a complete guide to protection!
2. SQL SERVER NEWS AND VIEWS
(contributed by Ken Pfeil, email@example.com)
Andreas Junstream of @Stake discovered that three new vulnerabilities exist in SQL Server 2000 and 7.0 and Microsoft SQL Server 2000 Desktop Engine (MSDE) and MSDE 1.0, the most serious of which can result in the execution of arbitrary code on the vulnerable computer. These vulnerabilities include named pipe hijacking, named pipe Denial of Service (DoS), and a SQL Server buffer overrun. Microsoft has released Security Bulletin MS03-031, "Cumulative Patch for Microsoft SQL Server (815495)," to address this vulnerability and recommends that affected users apply the appropriate patch mentioned in the bulletin.
Microsoft released Notification Services 2.0 Service Pack 1 (SP1), a standalone release of Notification Services. If you have an existing installation of Notification Services 2.0, you install SP1 side-by-side, then upgrade existing instances. Instructions for upgrading instances are in the Readme.txt file. Detailed instructions are in the "Upgrading Notification Services 2.0 Instances to Notification Services 2.0 SP1" paper, available on the Notification Services Technical Resources Web site at http://www.microsoft.com/sql/ns/techinfo/default.asp . You can read about the changes in SP1 in the Readme.txt file available from the download page at http://www.microsoft.com/downloads/details.aspx?displaylang=en&familyid=79B34DA2-185F-455C-9365-96FFBC6DA608.
The voting has closed in SQL Server Magazine's Instant Poll for the question, "How much downtime can your system handle at any one time?" Here are the results (+/- 1 percent) from the 234 votes:
- 17% None
- 38% 1-15 minutes
- 27% Less than 3 hours
- 11% Less than 8 hours
- 7% Availability isn't a concern
The next Instant Poll question is "How would you describe your level of expertise with Data Transformation Services (DTS)?" Go to the SQL Server Magazine Web site and vote for 1) Expert, 2) Advanced, 3) Intermediate, or 4) Novice.

SQL Server Magazine and CSA Research have made available the Database Performance Portal. IT professionals conduct scalability studies, perform ad hoc systems health analysis, identify infrastructure bottlenecks, conduct off-site diagnostics, and qualify new hardware purchases.
You can protect your application systems by using traditional firewalls and intrusion detection systems, but SQL content firewalls provide an additional layer of security for your SQL Server data. Because content firewalls inspect the data payload, you can use them to implement security policies that are based on business rules and semantic concepts--a more powerful approach than simply blocking ports and IP addresses. In "Protecting Your Payload," Ron Ben-Natan explains how an SQL content firewall can help protect your data. Read this August SQL Server Magazine article at
Sgfubt321 is creating in Enterprise Manager a new database that has a data-file size of 50GB and a transaction-log size of 5GB. Every time sgfubt321 sets the data-file and transaction-log sizes, the system hangs for 10 to 20 minutes--until he has to delete the application. What causes this behavior?

Q. I'm trying to register a SQL Server instance through the new SQL Server registration option in Enterprise Manager. I receive a message that says, "A server with this name already exists," but the server doesn't exist in the SQL Server group that I'm trying to add the instance to. Why am I getting this message?
A. You'll receive this message if the server has already been registered through Enterprise Manager and added to a different top-level SQL Server group. You need to expand the other SQL Server groups in Enterprise Manager to see whether the server is registered in a different group.
Registering the same physical instance of SQL Server more than once might be convenient sometimes. You might want to connect to the same SQL Server instance by using different Net-Libraries for testing purposes or register the same server more than once under different user credentials so that you can test permissions. To register an instance multiple times, you create an alternative client alias that references the SQL Server instance. For example, you can register a SQL Server called MySQLServer more than once in Enterprise Manager by creating a client alias named MySQLServerNew and registering that name in Enterprise Manager. You create the alias by using the Client Network Utility. For more information about creating a client alias, read the SQL Server Books Online (BOL) topic "Managing Clients."
