At a client site recently I helped a customer move their Central Administration site to a new server to better fit their overall architecture goals. After using the SharePoint 2010 Products Configuration Wizard first to remove it from one server, and then to add it to the new server we found that the program menu shortcut for Central Administration was no longer working.
Even though we could manually navigate to the new Central Administration page from each server the program menu shortcut still directed us to the old url.
Update 12/21/2011 – Thanks to Chris Howell for pointing out this alternative!
“I’ve found that this change is applied by altering the Internal URL for the site within Central Admin > Alternate Access Mappings.”
After some digging we found a registry key that you can edit to correct this.
HKLM\Software\Microsoft\Shared Tools\Web Server Extensions\14\WSS\
Edit “CentralAdministrationURL”. This will have to be done on every server in the farm.
Remember to backup the registry before making any changes. It is my guess that a group policy setting or other security setting was preventing this change from being made by the wizard. If I figure out what was doing it I’ll update this post.
