I saw someone already answered to a degree, but I did want to mention that the best practice is to include your .NET target environment into your ASP.NET application. This way the target environment will be present.

The version number can be queried from the Windows Registry:

On windows, run regedit and navigate to this directory:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\InetStp\VersionString

Mine returns Version 6.0 because I am running Windows 2003 Server.

This is available directly from the SERVER_SOFTWARE server variable:

HttpContext.Current.Request.ServerVariables["SERVER_SOFTWARE"];

which is a string like "Microsoft-IIS/7.0".

NB, the string is empty for the ASP.NET development server ("Casini").

To get the IIS version of the webserver you can use the SERVER_SOFTWARE server variable. 

Request.ServerVariables["SERVER_SOFTWARE"];

It will return something like as follows:

Microsoft-IIS/5.0 (Windows 2000)

Microsoft-IIS/5.1 (Windows XP)

Microsoft-IIS/6.0 (Windows 2003 Server)

You can find a full reference of server variables here.

@AnthonyWJones "So the question becomes, How does an ASP.NET application determine what operating system it is running on?"

You can use System.Environment.OSVersion
