The Start IIS Web Site action will perform a start operation on the designated web site within IIS.
IgnoreFailure
When true, a failure to start the site is ignored and the update will continue. The action uses the site description, or Server Comment, to find the web site in IIS.
SiteName
This is the name or description of the web site on the IIS server. When the action executed, a site with this name on the server running the update is located. If a site is found, the site is started. When the action is rolled back, if a site was started during the execute phase, it is stopped.
