Purpose

This article provides steps to check the Microsoft ASP.NET component version and registration status.

Resolution

This error message may appear if Lab Manager is not using the correct version of Microsoft ASP.NET.

Verify that the Lab Manager server has ASP.NET version 2.0.50727 installed.

Click Start > Control Panel > Administrative Tools > Internet Information Services (IIS) Manager.

On the left pane, expand the entry for Local Computer and click Web Service Extensions.

Check that there is an item called ASP.NET v2.0.50727 and that its status reads Allowed. If the status reads Prohibited, right-click the item and click Allow.

Verify the ASP.NET version registered with Lab Manager.

Click Start > Control Panel > Administrative Tools > Internet Information Services (IIS) Manager.

Click Web Sites > Default Web Site > LabManager.

Right-click Lab Manager > Properties.

In the Virtual Directory tab, click Configuration.

For each of the following extensions: .asax, .ascx , .asmx , and .aspx , verify that the executable path version lists version 2.0.50727.

If the version listed is incorrect but the correct version of ASP .NET has been installed, use the iisreset command to update the version listed.

Open a command prompt. For more information, see Opening a command or shell prompt (1003892).

Run the iisreset command.
