  • I should really appreciate Abhishek Sinha to post such an useful and reliable topic in this blog. The two download links are very useful to us. Thanks for this effort.


  • Thanks for posting this. Two questions:

    1. The SQL Server 2005 SP4 system requirements exclude Windows Server 2003 and Windows Server 2003 R2. Will installations on those operating systems have to remain on SQL Server 2005 SP3? If so, what will happen when SQL Server 2005 SP3 is no longer supported? (According to normal policy, SP3 will be supported no more than 12 months after the release of SP4.)

    2. Does DAC stand for Dedicated Administrator Connection or Data-tier Application Components? The latter is a new feature in SQL Server 2008 R2 which is also supported in SQL Server 2008 SP2.

    Thanks for any help,

  • Hi Rob, DAC is Dedicated Administrator Connection. I think this would solve your problem.

    Since Service Pack 2 was relelased, numerous bugs have been fixed. They are available in cumulative update packages (6 to date). However, Microsoft recommends customers not to install these cumulative updates unless affected by one of the fixed bugs. That creates a dilemma for SQL Server administrators. You do not want to install a package if Microsoft recommends against it, but you also want to take pro-active action so that you can squash the bug BEFORE it affects you.


  • Hi Rob,

    Thanks for your questions.

    For question #1:

    Windows Server 2003 was inadvertently omitted from the main package page for SQL Server 2005 SP4.  Customers using Windows 2003 may upgrade to SQL Server 2005 SP4.

    For question #2:

    DAC stands for Data Application Component; which is a new feature in SQL Server 2008 R2.  SQL Server 2005 SP4 provides customers with SQL Server 2008 R2 in their environments to deploy and manage DAC’s.  To learn more about the DAC please visit technet.microsoft.com/.../ff381683(SQL.100).aspx.
