Step 2: Remove damaged Exchange-related IIS virtual directories

Step-by-Step Guide: How to repair Exchange-related IIS virtual directories -- part 2 of 4.

There are several different methods you can use to recreate the various virtual directories, as detailed in Microsoft Knowledge Base article 883380, How to reset the default virtual directories that are required to provide Outlook Web Access, Exchange ActiveSync, and Outlook Mobile Access services in Exchange Server 2003.

I am going to explain how to do it using a utility called the Metabase Explorer, which is a part of the IIS 6.0 Resource Kit.

  1. Expand the Default Web Site container in the IIS Manager, and you will see a list of all of the IIS virtual directories included in the default Web site. To get rid of a virtual directory, simply right click on it and select Delete.

  2. You will see a prompt asking you if you're sure you want to delete the virtual directory. Click Yes and the virtual directory will be removed.

    A word of caution: Not all virtual directories found under the Default Web Site are related to Exchange Server. You should only delete the Exadmin, Exchange, ExchWeb, Microsoft-Server-ActiveSync, OMA, and Public directories.

  3. Now we have to get rid of an Exchange remnant. Close the IIS Manager console and open the Metabase Explorer tool (located on the Start -> All Programs -> IIS Resources menu).

  4. Expand the LM container to view about a dozen subcontainers.

  5. Locate a container called DS2MB, right click on it and select Delete.

  6. You will now see the standard "Are you sure?" message. Click Yes and the container will be deleted.
