IT IN AN INTERNET SERVICE PROVIDER
(ISP)
WHAT MAKES UP THE IT TEAM OF AN ISP• Systems 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
IT IN MANUFACTURING

ROLES OF IT IN MANUFACTURING
• Database Administrator
• ERP systems
• Timeclocks
• Financial reporting
• HR issues
• System Administrator

IT ELSEWHERE
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
INTRO TO POWERSHELL
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
SIMPLE POWERSHELL EXAMPLE
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
• Exchange
• Office 365
• SharePoint
• SQL Server
