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.
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:
The worker process is configured to use an identity that differs from Local System.
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.
Restore Bypass Traverse Checking rights
Click Start, click Run, type gpedit.msc, and then click OK.
Expand Computer Configuration, Windows Settings, and Security Settings.
Expand Local Policies, and then select User Rights Assignment.
In the right pane under the Policy column, right-click Bypass traverse checking and click Properties.
Click Add User or Group.
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".
Restart the W3SVC and HTTP services
Open an elevated Command Prompt window. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
Type net stop w3svc.
Type net stop http.
Type net start http.
Type net start w3svc.
