The Microsoft SQL Server 2005 Setup program may take a very long time to be completed. Sometimes this time will be more than 24 hours.

You may see in the detailed SQL Server Windows Installer log that most of the execution time occurs in the Write_sqlXXX custom actions. These custom actions may include the following actions:

•	Write_sqlFileSDDL
•	Write_sqlRegSDDL
•	Write_sqlGroupMember

Note This symptom may occur when you install software that also installs SQL Server 2005, such as Microsoft System Center Data Protection Manager (DPM) 2007.

When the primary domain has many external trust relationships with other domains or many lookups are performed at the same time, the time that is required to look up domain group names may increase significantly. Therefore, the time that is required to install SQL Server 2005 may increase.

Installation information

You can start the slipstream hotfix installation of SQL Server 2005. The term "slipstream" means that SQL Server Setup first merges the hotfix files together with the setup files that come from the SQL Server 2005 installation media. Then, the Setup program starts an installation that avoids the problem. To start the slipstream hotfix installation, follow these steps:

1.	Extract the hotfix package file in a folder. You obtain some .exe files that resemble the following files: • AS2005-KB901530-x86-ENU.exe • SQL2005-KB901530-x86-ENU.exe • DTS2005-KB901530-x86-ENU.exe • NS2005-KB901530-x86-ENU.exe • RS2005-KB901530-x86-ENU.exe • SQLTools2005-KB901530-x86-ENU.exe • SQLSupport2005-KB901530-x86-ENU.exe
2.	At a command prompt, run these .exe files by specifying the /X switch to extract these .exe files into different folders. For example, run the following commands: AS2005-KB901530-x86-ENU.exe /X:C:\QFE\AS SQL2005-KB901530-x86-ENU.exe /X:C:\QFE\SQL DTS2005-KB901530-x86-ENU.exe /X:C:\QFE\IS NS2005-KB901530-x86-ENU.ex /X:C:\QFE\NS RS2005-KB901530-x86-ENU.exe /X:C:\QFE\RS SQLTools2005-KB901530-x86-ENU.exe /X:C:\QFE\Tools SQLSupport2005-KB901530-x86-ENU.exe /X:C:\QFE\SqlSupport After you extract these .exe files, the .msp files appear in the following folders: • C:\QFE\AS\hotfixas\files\sqlrun_as.msp • C:\QFE\SQL\hotfixsql\files\sqlrun_sql.msp • C:\QFE\IS\hotfixdts\files\sqlrun_dts.msp • C:\QFE\NS\hotfixns\files\sqlrun_ns.msp • C:\QFE\RS\hotfixrs\files\sqlrun_rs.msp • C:\QFE\Tools\hotfixtools\files\sqlrun_tools.msp • C:\QFE\SqlSupport\msp\sqlsupport.msp
3.	Install SQL Server 2005 by running a command that resembles the following command: <SQLInstall>\Servers\setup.exe SQLSUPPORTPATCH="C:\QFE\SqlSupport\msp\SqlSupport.msp" HOTFIXPATCH="C:\QFE\AS\hotfixas\files\sqlrun_as.msp;C:\QFE\SQL\hotfixsql\files\sqlrun_sql.msp;C:\QFE\IS\hotfixdts\files\sqlrun_dts.msp;C:\QFE\NS\hotfixns\files\sqlrun_ns.msp;C:\QFE\RS\hotfixrs\files\sqlrun_rs.msp;C:\QFE\Tools\hotfixtools\files\sqlrun_tools.msp" <OtherParameters> Note In this command, <SQLInstall> is a placeholder for the folder of the SQL Server 2005 installation media. <OtherParameters> is a placeholder for the additional parameters that you specify.

To work around this issue, you can use one of the following methods:

Method 1
Temporarily disable the network on the computer on which the SQL Server 2005 Setup program is running. To do this, either disconnect the network cable or type the following command at a command prompt:Note This workaround will not suceed when you are installing a SQL Server failover cluster.

Method 2
Follow the steps that are listed in the following Microsoft Knowledge base article to restrict the lookup of isolated names in external trusted domains:

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

This symptom may also occur when you install DPM 2007. When you install DPM 2007, it may take a very long time on an installation of SQL Server 2005. Because the DPM 2007 installer will install SQL Server 2005 from DPM 2007 DVD media, we do not recommend that you perform a slipstream installation of SQL Server 2005 by using this hotfix. Use Method 1 in the "Workaround" section when the DPM 2007 installer starts to install SQL Server 2005.
