PsExec is a great utility for executing commands remotely – and it works especially nice for things like installs (MSIs) that require certain permissions during installs. This is much easier than configuring telnet on the remote server to allow this. We’ve been using this on our build servers to push our development and pre-production environments.
I originally heard of this one from Visual Build Pro – they have a template that relies on PsExec being install on the build machine.
PsExec is yet another great utility from SysInternals.
