Alternate access URLs have not been configured (SharePoint Server)
APPLIES TO: 2013 2016 2019 Subscription Edition SharePoint in Microsoft 365
This health analyzer rule only applies to SharePoint 2010 as this was removed in KB4011601 for SharePoint Server 2013 and KB4011576 for SharePoint Server 2016.
Rule Name: Alternate access URLs have not been configured.
Summary: A default zone URL must not point to the computer name of a front-end Web server. Because this installation has more than one front-end Web server, an incorrectly configured default zone URL can result in a variety of errors, including incorrect links and failed operations.
Cause: A default zone URL is pointing to the computer name of a front-end Web server.
Resolution: Change the default zone URL to a URL that differs from the computer name of any front-end Web server.
