I am trying to install the Replication components for SQL Server 2008R2, on technet website it says:
On the computer that is running IIS, insert the SQL Server 2008 R2, SQL Server 2008, or SQL Server 2005 CD and run Setup.exe.
In the SQL Server Installation Wizard, on the Components to Install page, click Advanced.
On the Feature Selection page, click Client Components, and then click Connectivity Components to install the SQL Server replication components
But the CD is lost, is there anyway to download the components or the setup files online?
Select @@version Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Developer Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)
You might get away with using the eval ISO.
Try download that, burn it to a disk (or mount it by other means) and see if it will cooperate. It’ll certainly contain everything, assuming it is as happy to be used to update your licensed install as it is an eval one.
EDit: I’ve removed the link as it was incorrect. It looks from trying to search on their site that SQL 2008r2 eval isn’t available direct from MS any more. You might be able to find it elsewhere though.
