In the Virtual Server List window, click Default Web Site.
In the Virtual Server Settings window, in the Virtual Server Management section, click Define managed paths.
In the Define Managed Paths window, in the Add a New Path section, enter CertSrv in the Path text box. In the Type section, click Excluded Path. Click OK.
