Perfomance Questions

I have a few questions.
First: We have a quad Xeon 500MHz server running SQL2K
and Win2K. All SPs are applied. Sometimes the
performance becomes an issue. My boss wants me to go
through and kill some processes when that happens. Are
there any adverse reactions to that?
Second: We also have a Terminal Server with Win2k3
running. Does anyone know of any performance issues with
this?
Thanks.
DonDon,
If the solution is to kill processes, you need a better solution.
Killing a process naturally affects the user of that process. Depending on
how the client and T-SQL code is written this can range from harmless but
annoying to leaving data in a logically incomplete state. (It will not
physically corrupt the database, but logical corruption is just as
troublesome.)
The thing to do is investigate the processes that are candidates for
killing, figure out what is wrong, and help the developer/user to correct
the problems. (Famous bad query: multi-table cartesian product to get just
a few rows. Done by people who do not understand joining.)
