Just going to copy some text i posted on another forum, hope it helps:

One thing i never saw mentioned in running both versions at once was to seperate the application pools that the sites run in.... so i figured i'd pass it along on how to do so...
- Right click on "My Computer"
- Choose "Manage" then expand "Internet Information Services"
- Right click on "Application Pools" and choose "New / Application Pool"
- Give it a name like "2.0 Framework"
- Click "OK"
Now after the install of 2.0 framework, you are going to see a new tab "ASP.NET" when you right click and choose properties from one of your existing web applications... go to that tab and make sure that its mapped to 2.0 framework and not 1.1.... now choose the "Home Directory" tab and set the Application Pool to the new pool you just created... otherwise your app may throw very non-descriptive errors (more or less just "Service Unavailable")

It's a security issue. Check out this link to setup the ASP.NET user with the necessary rights:

Hi,

In the IIS, check the version of ASP.NET used for your application.

To do that, right click on the virtual directory - select properties and you will find the ASP.NET Tab in the properties Window.

Swtich to that tab and in the dropdownlist, select the 2.0 version. Click Ok 2 times to exit.

Write back if this doesnt solve your issue.

Thanks.
