SYMPTOMS

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 this problem occurs, you must restart IIS, or you must restart the process that uses the IIS ADSI provider.

This problem is likely to occur for the SharePoint Timer service (OWSTimer.exe) in Microsoft Office SharePoint Server 2007. When this problem occurs for the SharePoint Timer service, you may experience the following symptoms:

• In SharePoint Server 2007, tasks that are scheduled do not run.

• On the SharePoint Web front-end server, you see repeated errors in the Application log in Event Viewer. These errors usually include one of the following three events:

• Event ID 6398
• Event ID 6482
• Event ID 7076

For example, you may see an error message that resembles the following:
Event Type: Error
Event Source: Windows SharePoint Services 3
Event Category: (964)
Event ID: 6398
Date: 11/7/2007
Time: 5:45:38
