I disconnected the server from the farm using SharePoint Config Wizard. Once that was finished I went into central admin and removed the server,
- On the SharePoint Central Administration Web site, in the System Settings section, click Manage servers in this farm.
- On the Servers in Farm page, locate the row that contains the name of the server that you want to remove, and then click Remove Server.
The problem is that when I go into the Health Analyzer the now removed/disconnected/trashed server still shows up as having issues. How can I remove the server so that the errors will go away?
