Fixing ReportServerVirtualDirectory element is missing

Thanks to the post from Danalive on the sql msdn forums by adding the characters ReportServer between the ReportServerVirtualDirectory tags in C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\ReportManager\RSWebApplication.config the error message of "The reportservervirtualdirectory element is missing" disappeared and I could access the Reporting Services homepage.
This weekend I had to rename the server as part of the GoLive procedure with this server. Sure enough, the rename of the server caused a lot more errors. There are a couple of pages on the MSDN site with instructions - Basic overview and instructions for renaming SQL2005 and Renaming a Report Server.
So far I've had several issues with this server - SQL2005 seems to have the buggiest and most unstable installation routine I've ever seen.
