ASP.NET Tab Missing

A common issue we see customers having is after installing ASP.NET 2.0, the ASP.NET Tab is missing from IIS.

This tab is used for setting the version of ASP.NET and a lot of other things.

aspnettab

When this tab is missing, it can be rather difficult to get it to appear.  So we now have a way to fix this quickly and easily.  Just download the file from this link and follow the steps below:

asptabtest.zip

This tool will run and fix the problem and get the tab to appear properly.  The steps to run this tool are:

 

  1. Close the IIS Management Console (inetmgr) and *any* other open MMCs.
  2. Run the asptabtest.vbs. It will check various known issues, correct some of them, and write results to a log file. Use the output to determine whether the issue is resolved, and if not, what steps to take next.
  3. Also note that after making any corrective changes to COM/DCOM settings, specifically DCOM security settings, make sure to either terminate (kill) ****ALL**** dllhost.exe processes, OR reboot the computer ****BEFORE**** testing again. Otherwise you may have well 'fixed' the problem, but a latent dllhost will prevent things from working. This is seen consistently when DCOM permissions were the problem.

Below is the output log of a working machine to give you an idea of the things it checks:

 Bellow is what the output log of a working machine will look like... It also shows the different things the script checks.
