How to install SQL Server 2005 SP3

Applies to: Microsoft SQL Server 2005

Download SQL Server 2005 SP3.

Please download SQL Server 2005 SP3 from here.

Risk Analysis.

- After SQL Server 2005 SP3 has been applied, it cannot be removed without uninstalling SQL Server 2005 completely.
- Test it on a test environment.
- Contact vendors of third-party software using your database server and get their approval.


- Use windows authentication instead of SQL Server Authentication when applying SP3.
- The windows account used to run the SP3 setup program must have administrator privileges on the computer where SP3 will be installed.
- Disk space needed for the installation:

Permanent 50 MB - SQL Server installation directory
1 GB - System drive
At least 500 KB of free space on system databases (better if you set autogrow on)
Temporary 600 MB - Temp Directory
334 MB - SP3 package. Remove it after applying SP3

Pre-installation tasks.

- Backup system databases.
- Backup user databases.
- Back up your Analysis Services databases, configuration file, and repository.
- Pause mirroring.
- Enable named pipes on your SQL Server 2005 server.
- Disable DDL Triggers.
- Verify that SQL Server 2005 Service Accounts are not disabled.
- Resources that have dependencies on SQL Server resources must be removed or taken offline prior applying SP3 .
- Stop all applications and services that make connections to the instance being upgraded. You cannot stop services in a failover cluster environment.

In case of a failover cluster environment, configure Microsoft Distributed Transaction Coordinator on the cluster.  Also, verify the following services are running on both nodes:

- Task Scheduler
- Com+ System Application Service
- Cryptographic Services
- Remote Registry Service
- Server


In case of a failover cluster environment, please consider the following:

- Do not stop the cluster service during installation or before applying SP3.
- Do not stop any running processes before running SP3 Setup.

Normal (non-clustered) installation:

- To install SQL Server 2005 SP3, run the self-extracting package file. Run SP3 Setup.
- After applying SP3, install cumulative update package 1 for SQL Server 2005 Service Pack 3

Installing SP3 on a failover cluster environment:

- Run SP3 Setup on the active node.
- After applying SP3, install cumulative update package 1 for SQL Server 2005 Service Pack 3 on the active node.

Post-installation Tasks.

- Restart each node of the cluster.
- Restart services that have dependencies on SQL Server.
- Verify proper operation of client applications.
- Backup system databases after successful installation.
- If the cluster was using mixed mode authentication, please verify it was not changed to Windows Authentication. Click here for more information.
