Sql-server – Enable SSMS in SQL Server 2005 Developer Edition

As per MSDN you can't install SQL Server 2005 Enterprise Edition on Windows XP. It's not supported. It seems that you can install client tools, BOL and some legacy tools, but not the database server engine itself.

So to answer your question: the SQL Server engine has very likely not been installed when you run setup, so neither you can connect to it, nor you can start any SQL Server service.

As a result of the replication job failure, you could respond with an xp_cmdshell statement to perform a Windows function: http://msdn.microsoft.com/en-us/library/ms175046.aspx

xp_cmdshell needs to be enabled in your Surface Area config: http://msdn.microsoft.com/en-us/library/ms190693.aspx
