I have a hudson setup with a single master pc (running win-xp) and 12 slave pcs (running win-xp and a few of them win2k), running hudson version 1.334 currently. The hudson master is running as a windows service. The hudson slaves are run as java clients, started through 'javaws http://master:8080/computer/slavename/slave-agent.jnlp' . Btw, I tried to get the slave also running as service, but I never managed to get the right permissions when I run the slave as a service. The jobs are written in shell commands, and executed on the slaves using cygwin sh. The hudson slave park is partitioned this way: * 3 slave pcs contain TriMedia based hardware boards. Jobs compile   test suites on the pc and run the executables on those boards. * The other 9 are used for pc jobs. Jobs compile test suites on the   pc and run the executables on a TriMedia simulator on the pc. I labeled the group-of-9 'windows'. In order to run a testsuite with different configurations (optimisation level, library set, etc) I use matrix jobs on my 'windows' queue. Using matrix jobs, I ran into bug 936, so I applied the workaround by adding -Dhudson.model.Hudson.flyweightSupport=true to C:\hudson\hundson.xml on the master.
