STORIES FROM EDUCATION • The First Few Weeks • The Paranoid Grad Student • ROTC • Overall Adventures

IT IN AN INTERNET SERVICE PROVIDER (ISP)

WHAT MAKES UP THE IT TEAM OF AN ISP • Systems Administrators • Mail Administrators • Webserver Administrators • Network Administrators & Engineers • Web Developers* • Technical Support

EXPERIENCE WITH TECH SUPPORT • First line of defense, sometimes the gateway to the other tech departments • Mostly phone support, some onsite support • Not scripted, as every call is different • End user could be a personal or business account • Customers are human, so add a personal touch • Pay attention to others on the team and learn from them • Don’t be afraid to talk to other departments to learn about their jobs so that you can do your job better in supporting them as well, since calls may come in for them

STORIES FROM ISP I.T. • The “I Want to Talk to the Manager” Dilemma • Becoming Familiar with Clients

MOTTO OF MANUFACTURING If it’s broken, fix it. If it’s working, don’t break it.

ROLES OF IT IN MANUFACTURING • Database Administrator • ERP systems • Timeclocks • Financial reporting • HR issues • System Administrator • Network Administrator • Troubleshoot technical issues with machines • Phone system (PBX) administration • Desktop support

STORIES FROM IT IN MANUFACTURING • Sensitive Data • Security Checks • Small Team to Large Client Base

GENERAL NOTES ON IT • IT roles may be siloed – where you can specialize in a part of IT and stay with it • Smaller companies try for more jacks of all trades to watch their IT costs • A lot of companies see IT as nothing more than an overhead department, despite the necessity • Consultants are jacks of all trades • Managers of IT departments may or may not have technical experience; some places put managers in place with business/team building skills rather than technical know-how

AGENDA • What is it • Why you should care about it • What products can benefit from it • System requirements • Resources

WHAT IS POWERSHELL? • .NET Scripting Language from Microsoft used for task automation and configuration management • Available for Windows XP and later • Comes with newer Windows operating systems • Can be used to replace batch files and VBScript files • Extensible automation engine

WHO CAN BENEFIT FROM POWERSHELL? • Developers • System Administrators • Mail Administrators • Database Administrators • SharePoint Administrators • Anyone who has tasks using the .NET Framework that can be automated

OBJECT-ORIENTED NATURE OF POWERSHELL

WHY YOU SHOULD CARE ABOUT POWERSHELL • Managing one user in a GUI = easy; managing hundreds of users in a GUI = time-consuming • Many click-click-click processes can be automated • Automating processes with a script makes processing quicker, giving you more time to tackle other issues or projects • VBScript is a thing of the past; a lot more products are using PowerShell for administration

WHAT CAN IT AUTOMATE? • List all computers on a network, with their operating system and service pack level • Start a service on multiple computers • Manage Active Directory users • Scrape all the event logs on your network for a particular error • IIS website setup • And many more!

PRODUCTS THAT BENEFIT FROM POWERSHELL ADMINISTRATION • Active Directory • VPN • Exchange • BitLocker • Office 365 • IBM Websphere MQ • SharePoint • System Center • SQL Server • Windows Compute Cluster Server • Windows Server • VMWare vShere • IIS • Network Administration
