SQL Server 2008 / Reporting Services

Since this has taken me four days to solve this one and, with almost no help from Google, I thought I'd log it here in case anyone else has this most bizarre problem.

Scenario: You retrospectively install Reporting Services to an existing installation of SQL Server 2008. You try to configure it using "Reporting Services Configuration Manager" and as soon as you click "Find" you get "Invalid Class"1 and no other information.

These two links gave me the clue, they're essentially both the same. What they say is to run WBEMTEST3 and connect to the Reporting Services WMI thingy.


Then run the query, "SELECT * FROM __NAMESPACE". When I did this I got:

 Note: TWO entries. The second one was a test database I had installed months ago and had removed at some point when I worked out that using the default instance of MSSQLSERVER was more convenient - but the registry(?) entries were still hanging around. I selected it by clicking on the offending entry and simply clicked "Delete"2 and then, bingo, the RS Config Manager sprang into action.

1I created the message box for this blog entry using VB.NET as I'd already fixed the problem and didn't want to recreate it.

2Blah, blah, blah, I take no responsibility for anyone cocking up a production environment and losing your company millions in downtime.

"The delivery extension for this subscription could not be loaded" when using SSRS

OK, so we upgraded our server farm and put on the latest "stuff" (SSRS, SQL Server etc.) and the engineers gave me two servers to play with - SQL01 & SQL02. The idea being that we used high availability to help keep the factory running. We employed a contractor to load up and configure everything. At this point I wasn't involved. My involvement was to move all the reports and subscriptions from the old servers to the new ones once the servers had been configured. All went swimmingly, until I actually started to fire off the subscriptions to test them. Randomly (like 5 out of 10) I got the error in the title. I would edit the failing subscription and/or change the schedule time and it would work. I finally got around to moving 81 subscriptions for the same report (all slightly different parameters going to about 6 different engineers). I press the "go" button and every single one failed. Let's cut out the long story about how I went through about

The Scottish Holiday . After the trauma of the Astra-breakdown episode and the gutless hirecar, we'd recovered sufficiently to begin to enjoy the rest of our holiday with our friends at the Castle... Chapter Seven: One of the things my wife really wanted to see was a seal, or seals if she was really lucky. So we decided to take a day out and around the Mull Of Kintyre. We stopped at "St Columba's Footprints" and carefully studied the jumbled collection of rocks and seaweed. "No seals there dear, let's carry on" "Oh, alright then, never mind. But that's where we were told they are most likely to be." We drove on and took a gated road signposted " To The Lighthouse ". This took us right up into the hills. As we were driving slowly along admiring the view, my wife whispered quietly... " Ooh, look an Eagle! " "Stop that, that's not funny." "No, really. Stop the car."
