SYMPTOMS

Consider the following scenario:
  • You have Internet Information Services (IIS) 7.0 installed on a computer that is running Windows Vista or Windows Server 2008.Or, you have IIS 7.5 installed on a computer that is running Windows 7 or Windows Server 2008 R2.
  • You restart IIS by using the IIRESET /RESTART command.
In this scenario, IIS World Wide Web Publishing Service (W3SVC) does not start. Additionally, the following events are logged in the application event log:

Log Name: System
Source: Service Control Manager
Event ID: 7001
Description: The World Wide Web Publishing Service service depends on the Windows Process Activation Service service which failed to start because of the following error:

After starting, the service hung in a start-pending state.

Log Name: System
Source: Service Control Manager
Event ID: 7022
Description: The Windows Process Activation Service service hung on starting.

CAUSE

After IIS 7.0 or IIS 7.5 starts, Windows Process Activation Service (WAS) calls the LookupAccountName function to resolve account names on the local system. If no name is succesfully resolved, the LookupAccountName function tries to resolve account names by using domain controllers (DCs) trusted by the local system. Depending on the configuration of the DCs, the LookupAccountName query may take more than 30 seconds to be completed. In this situation, it takes a long time to start WAS. Additionally, W3SVC does not start because W3SVC depends on WAS.

WORKAROUND

To work around the issue, use one of the following methods:
  1. Make Sure that Domain Controllers (DCs) can be pinged and accessed by using RPC communication.

    Note The LookupAccountName API uses RPCs to communicate with the DCs.
  2. Manually restart IIS. To do this, perform one of the following operations:
    • Run the following command:
      net start w3svc
    • Start the World Wide Web Publishing Service (W3SVC) in the management window of Windows Services.
  3. If there are many DCs, set the LsaLookupRestrictIsolatedNameLevel registry key to 1 to speed up the LookupAccountName query.

    Note For more information about how to set the LsaLookupRestrictIsolatedNameLevel registry entry, click the following article number to view the article in the Microsoft Knowledge Base:
    818024 How to restrict the lookup of isolated names in external trusted domains by using the LsaLookupRestrictIsolatedNameLevel registry entry
