This is good information to know. Thank you for the question.

In the URL given in the explanation, the phrase "The resource database (mssqlsystemresource)" appears four times. MS thoroughly emphasizes the outcome of restoring system databases.

Definitely good to know. It seems like Microsoft needs to put a little more thought into this. Since this has to be done from the original media, it should be smart enough to detect you are not running at the same patch level of the media and provide instructions to accomomdate for that.

I didn't think I knew this, but I got it right! When I saw the possible answers, I realized I'd seen this symptom before and was able to deduce the correct answer.

I was working on a customer's databases with which I was unfamiliar. They had a two servers, a primary and secondary (the app server handled failover). The primary was RTM while the secondary had service packs. Not only that, but the server net libraries on the primary were later service pack versions! I applied service packs, but had been left wondering how that could have happened. Now I know what might have happened to cause the discrepancy!

Good Question. Smile

I just joined yesterday, and have been going through some of the old QotD's. Seeing a question like this that makes you think and do some research is much better than some of the stuff I have seen in here. Wink

What is:
SELECT 35 / 5 - 2


That doesn't do much to stimulate brain activity. Wink

Thanks,

This is something I didn't know and which is probably quite important.

MS does mention that service packs and hotfixes should be reapplied
Important The resource database (mssqlsystemresource) is restored from SQL Server 2005 distribution media. When you rebuild the resource database from distribution media, all Service Packs and QFE updates are lost, and therefore must be reapplied. Before you proceed, see [REBUILDDATABASE] for more information.
However under the [REBUILDDATABASE] entry, there's no further mention of this, so I suspect a lot of DBAs who have to rebuild the master database don't get back to where they should be!

Of course, it does say that the most recent backup of the master database should be restored as soon as possible would would have the effect of updating it, but there is still great scope for error here.
