I am trying to install sql server 2005 in my system after uninstalling a previous version of corrupted sql server 2005. But while starting to install sql server services during installation process an error is occurring. The error is as follows: 

Microsoft SQL Server 2005 Setup The SQL Server service failed to start. For more information, see the SQL Server Books Online topics, "How to: View SQL Server 2005 Setup Log Files" and "Starting SQL Server Manually." Error Number :29503

SQL 2005 will not install on a stock SP3 system. It relates to MSXML 6.0, and the versions installed by SQL2005 and SP3. See this KB article.

The normal fix is to use the Windows Installer Clean-up utility to remove the references to MSXML 6; unfortunately, Microsoft has removed that tool from their website.

Is there a reason you have to use SQL 2005? If not, just go to SQL Express 2008.


Seems your PC is not a domain member? If that's the case, you can try creating an empty REG_SZ value named Domain in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters of your registry. Then try to start SQL Server (any edition) again.

Or may be http://support.microsoft.com/default.aspx/kb/920114 will help you


If you can find your error logs you'll get an idea of what the problem is. They can be found in: C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\Log\Summary.txt

This can sometimes happen if you're installing SQL Server 2005 on a system with multicore processors. http://support.microsoft.com/kb/954835/en-us

Also which version and SP of SQL 2005 have you tried installing?
