If you are a Unix admin and also have to maintain Windows servers, you will find winexe a must command line utility to have in your arsenal.
Until recently I have been able to do this only on Linux boxes. I have compiled it and it works great however, on Mac OS X I have not had any luck until a few days I came across this site. There are also links provided to the winexe binary packages here.
So, once you install it, the usage is simple:
Here is a quick exemple.
To get the route table on the Windows machine (using your correct IP address and other appropriate information):
winexe -U YOURDOMAIN/YourAccount%YourPassword //172.16.2.xxx 'route print'
If you want to start a Windows service:
winexe -U YOURDOMAIN/YourAccount%YourPassword //172.16.2.xxx 'net start "Service Name"'
Or to kill a Windows service:
winexe -U YOURDOMAIN/YourAccount%YourPassword //172.16.2.xxx 'Process.exe -k 1110'
[crarko adds: I haven't tried this, but the first link will get you to the source code (GPL) so you can examine and build it for yourself. The second link points to a number of useful tools you can run in Terminal to work with Windows machines. I did a quick check of MacPorts and Fink and they didn't seem to have winexe, at least not as a standalone package.]
