Has anyone been frustrated by the plethora of login requests SharePoint makes when you're working with Office documents out of a document library? You have to log into the site, you have to log in to make a change to a document, and log in again to save that change back (sometimes). Annoying.
Well, you can eliminate some of these login requests by adding your SharePoint site to your machine's trusted domains:
To add a site as a trusted domain, open Internet Explorer. Select Tools...Internet Options. On the Security tab, select the Trusted sites icon. Press the Sites button. Type in the domain name of your SharePoint server (ex. "https://www.mysharepointsite.com") and hit Add. Hit OK on all the remaining dialog boxes until you're back to IE. This should help.
You can also follow the advice in this article and make a change to an XML file and reduce the number of login requests even further: http://articles.icscentral.com/Kb%20Articles/271/823553.aspx
