The cookie timeout is also limited by IIS and defaults to something low like 20 min. To change this:

1. Open IIS Manager.
2. Right click your site and select properties.
3. Select the ASP.NET tab and click Edit Configuration.
4. Select the Authentication tab.
5. Select Enable sliding expiration.
6. Set the Cookie timeout to a longer value. To set to 30 days, enter 30.00:00:00.
7. Click OK and exit IIS manager.
