Could not load the file or assembly Microsoft.Web.Administration Version=7.0.0.0 when running the Exchange Management Console

Earlier today I received the following error message while using the Exchange 2007 32bit Admin tools on a Windows 7 client computer, when trying to access information under ‘Server Configuration’ in the Exchange Management Console:
“Could not load file or assembly ‘Microsoft.Web.Administration, Version 7.0.0.0, Culture=neutral,PublicKeyToken=31bf3856ad364e35’ or one of its dependencies. The system cannot find the file specified.”
Error message Could not load file or assembly Microsoft.Web.Administration
To correct this error I opened the ‘Turn Windows features on or off’ screen and enabled the Internet Information Services (IIS) Web Management Tools, as shown below:

I then restarted the Exchange Management Console and the desired functionality was restored.
