This problem may occur when the Exadmin virtual server is not working correctly.

To resolve this problem, you must re-create the Exadmin virtual server in Internet Information Services (IIS). To re-create the Exadmin virtual server, back up the IIS metabase, remove the Exadmin virtual directory, remove the directory-service-to-metabase-replication component (Ds2mb.dll), and then restart the System Attendant service.

1. To back up the IIS metabase, follow these steps:
   1. Start Internet Information Services Manager.
   2. Right-click the server object, point to All tasks, and then click Backup/Restore Configuration.
   3. In the Configuration Backup/Restore dialog box, click Create Backup.
   4. In the Configuration backup dialog box, type the name of the backup file in the Configuration backup name box, and then click OK.
      
      Your backup is added to the Previous backups list in the Configuration Backup/Restore dialog box.
   5. Click Close to return to the Internet Information Services Manager main window.
2. To remove the Exadmin virtual directory, right-click the Exadmin object in Internet Information Services Manager, and then click Delete.
3. To delete the directory-service-to-metabase-replication component in the metabase, follow these steps:
   1. Start a command prompt, and then change to the drive:\Inetpub\Adminscripts directory.
   2. Type

      cscript adsutil.vbs delete ds2mb

      and then press ENTER.
4. In Services, restart the Worldwide Web Publishing Service and the System Attendant service.
   
   Restarting the System Attendant service restarts the Microsoft Exchange Information Store service, restarts the message transfer agent (MTA) stacks, and re-creates the Exadmin virtual directory.
   
   Note To open Services, click Start, point to Settings, click Control Panel, and then double-click Administrative Tools.

In Internet Information Services Manager, verify that the Exadmin virtual directory has been re-created. Open Exchange System Manager, and then verify that you can access and administer the public folders.
