  • Article

Applies To: Windows Server 2008 R2

The Internet Information Services (IIS) World Wide Web Publishing Service (W3SVC) requires both the Windows Process Activation Service (WAS) and the HTTP service to function correctly. If the HTTP service is not available, W3SVC will not be able to process HTTP requests.

Event Details

Product: Internet Information Services
ID: 1020
Source: Microsoft-Windows-IIS-W3SVC
Version: 7.5
Symbolic Name: W3SVC_HTTP_CONTROL_CHANNEL_CONFIG_FAILED
Message: The World Wide Web Publishing Service (WWW Service) failed to configure the HTTP.SYS control channel property '%1' properly. The data field contains the error number.

Resolve

Restore Bypass Traverse Checking rights

The World Wide Web Publishing Service (W3SVC) may fail to configure an HTTP.SYS control channel property if the following conditions are true:

  1. The worker process is configured to use an identity that differs from Local System.
  2. The Everyone group and the Users group do not have the Bypass Traverse Checking user right. By default, the Everyone group and the Users group have this user right.

To resolve this issue, follow the steps in Parts A and B.

To perform these procedures, you must have membership in Administrators, or you must have been delegated the appropriate authority.

A. Restore Bypass Traverse Checking rights

  1. Click Start, click Run, type gpedit.msc, and then click OK.

  2. Expand Computer Configuration, Windows Settings, and Security Settings.

  3. Expand Local Policies, and then select User Rights Assignment.

  4. In the right pane under the Policy column, right-click Bypass traverse checking and click Properties.

  5. Click Add User or Group.

  6. Type Everyone;Users, and then click OK.

    Note:  If you receive a message that an object named "Users" cannot be found, click Object Types, click to select the Groups check box, and then click OK twice.

    Note:  If you do not want to give the Everyone group and the Users group the Bypass Traverse Checking user right, you may be able to resolve this issue if you give the IIS_IUSRS group the Bypass Traverse Checking user right. To do this, replace "Everyone;Users" above with "IIS_IUSRS".

B. Restart the W3SVC and HTTP services

  1. Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Type net stop w3svc.
  3. Type net stop http.
  4. Type net start http.
  5. Type net start w3svc.

Verify

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the World Wide Web Publishing service is running, follow these steps:

  1. Open an elevated command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Type sc query w3svc, and press ENTER. The World Wide Web Publishing service is running if the state reported for the service is 4 RUNNING.
