A stress run is not exclusive to unix.
You devise a test sequence which will put the computer under stress, usually to simulate the expected maximum load on the computer before giving it to live users.

I don't think you quite understand. a stress test is a category of test, not some sort of benchmark. What you do depends on what you're testing, and of that you've told us nothing. If you're stress-testing a DNS server, generate a lot of DNS activity. Stress testing a file server, generate a lot of file activity. stress testing a web server, generate a lot of network traffic. and so on.

For testing DNS, there are few toolsets you can check : TXDNS, an aggressive multithreaded DNS digger., BIND DLZ FAQ's, dns-grind - pentestmonkey.net.
For file server - there are many tools, depending on what exactly you are trying to achieve, Iozone Filesystem Benchmark is a good start, especially the 'fileop' that's included in the kit.
