Sitecore Shell Override Folder Is Invalid Error

Recently, when trying to setup a build server to deploy a Sitecore project, I came across this error after logging into Sitecore:

sitecoreshell_override_is_invalid

Or in more detail:

Server Error in '/' Application.
The directory name c:\websites\dev.sitecore.website.com\website\sitecore\shell\override is invalid.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 
Stack Trace: 
[ArgumentException: The directory name c:\websites\dev.sitecore.website.com\website\sitecore\shell\override is invalid.]
System.IO.FileSystemWatcher.set_Path(String value) +405
Sitecore.Web.UI.XmlControls.FolderControlSource.InitFolderWatcher(Boolean deep) +67

Sitecore.Web.UI.XmlControls.ControlSourceFactory.CreateControlSource(XmlNode configNode) +241

Looking in \sitecore\shell\ the override directory didn’t exist. Apparently, this folder is not created for you automatically when you create a fresh install of Sitecore. If it can’t find it, Sitecore throws a tantrum. The resolution was pretty simple.. create it!

sitecoreshell_override_is_invalid_1

Refreshing the page immediately after creating the folder, didn’t do much and the same error displayed. Ater performing an IIS reset however, the error disappeared and the content editor loaded.
