SBS 2011 Standard Edition Setup Crashes Unexpectedly

Small Business Server 2011 Standard Edition Setup may unexpectedly crash. When the crash occurs, setup will terminate and the user will see the following window.






The sbssetup.log file that is located at c:\program files\windows small business server\logs will contain the following error:

[4624] 110318.160407.0793: TaskManagement: In TaskScheduler.RunTasks(): The "ConfigureSharePointTask" Task threw an Exception during the Run() call:Microsoft.WindowsServerSolutions.Common.IWorker.IISConfig.IISConfigException: IIS Server Administration threw an exception. See inner exception for details. ---> System.IO.FileLoadException: Filename: \\?\C:\Windows\system32\inetsrv\config\applicationHost.config
Error: Cannot commit configuration changes because the file has changed on disk

The issue can occur because of a timing problem during the setup process. Another process has made a change to the applicationhost.config file while SBS setup is trying to also edit the file.
