There may be instances when you want to expose your server, by using HTTP, to the Internet to allow other sites to crawl your server. The instructions in this section enable a SharePoint Portal Server computer with access to the Internet to crawl another SharePoint Portal Server computer across the Internet. Currently, SharePoint Portal Server only supports HTTP crawling. HTTPS crawling is not supported.
SharePoint Portal Server cannot use the default content access account to access another SharePoint Portal Server over the Internet. You can only specify an NTLM trusted domain account as the default content access account, and you cannot use NTLM for Internet crawls. You must specify an access account for the site path to the SharePoint Portal Server you want to crawl.
If the workspace you want to crawl has enabled Anonymous access (the Internet Guest Account is assigned to the reader role on the workspace), you do not need to use Basic authentication and do not need to perform the following procedure. You need only create a content source to the workspace on the other server. For information about assigning the Internet Guest Account to the reader role on a workspace, see the section, Security Settings earlier in this chapter.
After completing the preceding steps, create a content source to the workspace on the SharePoint Portal Server computer that you want to crawl.
