Sounds like you set it up to log in as 'sa' and you don't have the password correctly entered. You may need to try the install again. Pay attention to...

If you're moving up to 10TB systems and you haven't handled that level before, I'd strongly recommend getting some consulting help in on your project. Anything past 1-2TB requires specialized...

I'd guess either differences in data or statistics being out of date on one of the servers. Hard to say without seeing the execution plans.

Performance tuning is a large topic. Gail Shaw has some excellent articles[/url] on Simple-Talk. I'd start there. Once you've got those under your belt, pick up a copy of my...

So don't use sp_who2. That's the old approach anyway. Dive into the DMOs and get lots of good information.sys.dm_exec_requests will show you what's currently running. You can combine that with...

Your trigger needs to be on the child table and it needs to say "UPDATE Parentable..." in order for the parent table to be updated.

Modify the procedure that updates the child table so that it also updates the parent table. That'd be my first approach. You could also look at setting up a trigger...

I'd check the execution plans. Something has to be changing there. I'm not a fan of cross-database queries anyway.

Especially on a reporting system I would not suggest ditching parallelism. Usually reporting systems get the most help from parallelism.
However, if you've done the research and you're getting excessive waits...

You have to do the hard slog. Gather performance metrics, capture wait stats, get the longest running and most frequently called queries, then start addressing the issues. There are extremely...
