Thanks for the followup, Kathi, and this is an interesting one. And a bug for MS to fix in SP5 and just grant those rights when you change the service...

Since tempdb is used for scratch space for worktables, ordering, groups, etc. it's size really depends on the queries and loads that you throw at it. There's no good tool...

I'll think about it. Not sure how hard that is until I dig into the code. Part of it is we're looking at rewriting some sections in the next few...

We never added that functionality in there, but it's a good idea. You can email the author, or send a private message.

How are you transferring the data? I suspect that some tasks may not work, but I'd think a simple data transfer will work.

How are the clients connecting you SQL? Protocol and addressing?

SQL is not dependent on the Internet, but perhaps you have some name resolution or something that is.

Thanks for the complements and apologies for the delay in responding.

I think that using a separate account for each service is a pain. A real admin pain, but it's a...

OK, we are looking at this differently. The question asks "which of these accounts", not which type or if there is a better 5th answer not given.

Limited Service is not...

Profiler won't really give you a load. Follow John's advice and track some counters. A single day isn't really that good a test, more like a whole week or 4-5...

Why would you do this? It is a bad idea and there's real reason to do it. Each time the trigger ran it would create a new table, which...

off the cuff:

set rowcount 1

select @i = col1, @j-2 = col2, @k = col3

from mytable

where intcol is null

if exists( select intcol from mytable

...

I think if you set a role in msdb for them and grant execute on sp_startjob, they can do it.

Alternatively, create a job that queries a table (some new one)...

I agree with Yelena. You're playing with fire here.

Don't say horse. Got enough horses, too many horses, shoveling too much as it is.

I didn't see a great map when searching on Google.
