What do you do day-to-day as an IT Administrator?

I am getting ready to create several short screencasts on Windows Server 2008 R2 that talk about the benefits to administrators with R2.  There are quite a few.  I want to create a list of stuff you do everyday, so I can focus the screencast topics.  I think I have a pretty good list, but let me know if I am off the mark.  My list of topics is below. 

So I have three questions for all of you and please email me any suggestions or comment: 

• What did I miss?
• What topics do you most want to see?
• Any topics you want to change or delete?

Topics:

• Installing and upgrading to Windows Server 2008R2
• Adding server roles and functionality
• Powershell common administrative tasks
• User and Group maintenance
• Directory Management and Replication
• Group Policy
• Folder Security, Access and Replication
• Security auditing
• Printers setup and configuration
