Updating from sp2 to sp3
And where do I find the right files, that don't require an internet connection during installation?
You might also make a slipstream install CD, which has SP3 integrated into the install CD.
Of course, it is only helpful if you can install from scratch, and not upgrade existing systems where you need to retain installed programs and settings.

Stopping the SQL Server agent isn't necessary - but if you have many jobs and are trying to make sure a job doesn't kick off just before you start, etc - that is a good plan. I also like to read the notes on the CUs released after a Service Pack and look for details about potential issues.
We also stopped some web application which had connection to our SQL Server databases.
Or will it wait until the TIME the Automatic Updates are set to ... I would have thought an Update to SP3 would supersede that time and start happening immediately.
The computers don't have an internet connection (only a small intranet) and have never been updated since first install.
