FIX: You may be unable to manage IIS by using Server Manager if two threads access IIS at the same time

Consider the following scenario. You have a process that has more than one thread. Additionally, the process uses the Internet Information Services (IIS) Active Directory Service Interfaces (ADSI) provider to access IIS. Two threads access IIS at the same time. In this scenario, you may be unable to manage IIS by using Server Manager.

When you try to manage IIS by using Server Manager, you receive a blank page, or you receive the following error message:When this problem occurs, you must restart IIS, or you must restart the process that uses the IIS ADSI provider.

Note This problem can occur for any process that uses ADSI to access IIS. For an example of this problem for the SharePoint Timer service (OWSTimer.exe) in Microsoft Office SharePoint Server 2007, see the "More information" section.
