This question was posted in response to the following article: http://help.adobe.com/en_US/ColdFusion/9.0/Installing/WSe9cbe5cf462523a07f098214121c918ef8 c-8000.html
Step 2 above refers to the directory for CF's neo*.xml files as being cf_webapp_root/WEB-INF/cfusion/lib/. That is indeed the location on a multiserver deployment (multiple instances), such as C:\JRun4\servers\cfusion\cfusion-ear\cfusion-war\WEB-INF\cfusion\lib.
But this page is in a chapter about 'Installing the Server Configuration", so the proper location (for CF Standard or Enterprise in the Server configuration) would instead be cf_root/lib, such as C:\ColdFusion8\lib.
Similarly, step 3 refers to how one would "edit the ColdFusion 9 cfusion/lib/adminconfig.xml", and again, in a Server deployment that would instead be cf_root/lib, as in C:\ColdFusion9\lib.
