- Click Start, click Control Panel, and then click Administrative Tools.
- Right-click Internet Information Services (IIS) Manager and select Run as administrator.
- In the Connections pane, select the computer name.

- Under Log File Rollover, make sure that Maximum file size (in bytes) is selected.
- If necessary, refer to the IIS Settings Schema article IIS 7.0: Configuring Logging in IIS 7.0 for the possible values.

If the Windows Process Activation Service (WAS) is configured correctly, IIS will serve pages successfully.
To confirm that WAS is executing successfully, perform the follow these steps:
- Open Internet Explorer.
- Browse to http://localhost or your Web site's default home page.
- Confirm that the expected page is displayed.
- Open the logs for the Web site and make sure 200 OK (request succeeded) is logged for the previous request. By default, Web site logs are located in the %SystemDrive%\inetpub\logs\LogFiles directory.
Note: If logging is set to centralized, the log file size will grow over time. The minimum possible (and configurable) log file size is 1 MB.
