If you are using Outlook (I was using Outlook 2007 or 2010) it did not matter in a local profile (not domain attached) to connect to a SBS 2008 server and the Exchange Remote Connectivity Analyzer tests pass you may need to apply the following steps.
Runas Administrator, start, run, cmd
cd %windir%\system32\inetsrv
.\appcmd.exe unlock config -section:system.webserver/security/authentication/windowsauthentication
.\appcmd.exe set config “SBS Web Applications/ews” -section:windowsAuthentication -useKernelMode:False /commit:apphost
.\appcmd.exe set config “SBS Web Applications/AutoDiscover” -section:windowsAuthentication -useKernelMode:False /commit:apphost
.\appcmd.exe set config “SBS Web Applications/oab” -section:windowsAuthentication -useKernelMode:False /commit:apphost
Open IIS manager, expand Messaging server -> Site -> SBS Web Applications -> RPC. On the /RPC Home, double click Authentication.
check if “Windows Authentication” is Enabled. If so, refer to the following steps:
Disable (Uncheck) “Enable Kernel-mode Authentication”.
You will have to perform an iisreset but for some reason my iis would not stop at that point and I had to reboot the server
Click Start, right click on “Command Prompt”, click “Run as Administrator”, input: iisreset /noforce
Not sure yet why kernal mode auth was enabled nor if that is a desireable setting.
Please note in my case domain connected Outlook clients worked fine and the Exchange Remote Connectivity Analyzer tests passwd.

Embarking on a project to upgrade Office can seem intimating to some users. The following are great end-user resources that should elivate some of that concearn.
Office 2010 Details
The biggest change for users when moving from Pre-Office 2007 to Office 2010 is getting used to the ribbon.
Introduction to Word 2010 and the Ribbon
Introduction to Excel 2010 and the Ribbon
I am also including two links (included below) that you can use for further resources. The first link provides you with both interactive guides and Excel workbooks that define what the command mappings are between the old and the new version. The second link is a more formal online training session on Office 2010.
Additional Resources
Interactive Guides à Interactively shows you the new way of performing old tasks using your web browser
Office 2010 commands and buttons printable list à Download Excel “Workbook” that maps old commands to new
Microsoft Office 2010 Online training

If you ever need to create a file of specific size for testing purposes siimply use the built-in fsutil command (XP and later)
The following command will create a 1 MByte file.
fsutil file createnew c:\temp\1mbfile.txt 1000000
Can also be used with a checksum generator/checker to verify the integrity of files.

All Control Panel Items in one folder on Windows 7.
Create a desktop folder with GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

In Windows 7 RTM gpresult no longer reports the policy for Computer Objects. The RSAT tools were recently released that allow you to perform a group policy results but that does not tell you what really made it down to the PC.
So how do you do this in Windows 7?
Browse to Applications and Services / Microsoft / Windows / GroupPolicy / Operational
Here you will find the events related to Group Policy Processing. You will find the Group Policies applied in a event with event id 5212
Don’t forget you can also use rsop.msc on Windows 7 in logging mode to see what gpo is currently applied.

There are now 16 services shipped in a 1 server install of Exchange 2007 SP1 on Windows 2008 SP2.
By default 13 of those are running.
This site has a good introduction on understanding the various Exchange service dependencies.

There is a new security vulnerability that exists in ActiveX (Microsoft Office Web Components) that is actively being exploited. This advisory was first made available on July 13. This is the second of two exploits in ActiveX so far for the month of July. This vulnerability can affect Windows XP users with Office 2003 installed. Vista/Windows 7 and Office 2007 are not known to be affected in tyheir default install configurations
What makes this vulnerability/exploit important is that the users PC can be infected by simply clicking on a link in an email, messenger or on a web page (dependent on ActiveX settings in the browser.) This can allow a unauthorized user to use your PC for uses that you do not authorize (remote code execution)
- There is a “workaround” that you may want to install to prevent the exploit from occurring
- Please note it removes browser functionality but as far as I know most users do not use this functionality. This will have to be taken on a case by case basis.
- If you are interested in deploying the workaround there is one listed in the “workaround” section http://support.microsoft.com/kb/973472 Click Enable Workaround - Fix Me
- No permanent fix is available at this time

While we are in the era of Windows 2008 (and SBS 2008) we need to consider new operating system tuning guidelines.
For example most partitions are aligned on 1 MByte boundries. To see what your boundries are use:
wmic partition get Index, Name, StartingOffset
