I've never done powershell. But know dos batch files inside and out anymore. I've used them to setup a full monitoring system on our hosted systems that provide a daily check in for all the servers. I also setup a weekly backup system that use 7-Zip to backup non SQL DBs and application data. It reports to a entral server and then I built a daily Access DB run that consolidates the info and sends daily e-mails for all the servers.

My prior position I was able to use similar install scripts to automate client upgrade installs as well. So I'm not a strict "I'm a DBA only" person. Someday I guess I will have to to learn powershell. But using DOS batch files can get you to the 90% level if you have a clue.
