The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
This Web site is usually the second Web site on the server. Connecting to the Web site through HTTP works correctly.
If you run a netstat -an command, you can see that a service is listening on port 443, but you cannot connect to it. This is caused by a new implementation in IIS versions 5.0 and later called Socket Pooling.
For additional information on socket pooling and how to disable it, click the article number below to view the article in the Microsoft Knowledge Base:
- Open the Security properties for the default Web site, and then select Server Certificate.
- In the wizard, click Assign an existing certificate, and then select a certificate from the list.
- When you have completed the wizard, click Web site tab, and then click Advanced.
- Delete all the entries that are listed in the SSL window.
- Click Server Certificate again, click Remove the current certificate, and click OK.
- Right-click the computer name in the Microsoft Management Console (MMC), and then click Restart IIS.
This problem usually occurs when you try to set up SSL on the administration Web site. IIS finds the SSL settings for the default Web site and listens on port 443. However, the default Web site does not have a certificate to correspond to that site. Therefore, no connection can be made, which is why you can see a server listening on port 443, but you cannot connect to the site.
