ColdFusion 9 no longer recognizes virtual directories on IIS after install of Apache

Hi - I have an application that has been working fine for over a year and now anything that references Virtual Directories no longer functions.  Here are the details: Coldfusion is running on Windows Server 2003 Enterprise. Using IIS6 for the web server on the same box. I have several virtual directories setup that reference files on another server on the same network. What I did to break things... I installed Apache (the latest release) along with PHP - but I set Apache up to listen on a different port (8080). Suddently any part of my code that tries to reference a file that is found through a virtual directory generates the following error: An error occurred when performing a file operation exists on file /serverpdfs/130kPDFs/137485.pdf. The cause of this exception was: org.apache.commons.vfs.FileSystemException: Could not determine the type of file "http://www.mybp-graphics.com/serverpdfs/130kPDFs/137485.pdf".. Here's the actual code that generated that error: <cfset filename = "http://www.mybp-graphics.com/serverpdfs/130kPDFs\137485.pdf">;           then within a table...      <cfif FileExists("#filename#")>     <td>Yes File</td>     <cfelse>     <td>No file</td>     </cfif> The "serverpdfs" is the virtual directory inside the website "mybp-graphics.com". If I look in IIS the directory is there, I can see all the files in it - it seems to be working fine. I first experienced the problem when we tried to open a PDF for viewing by using <CFCONTENT> - the same type error occurs. What is especially suspicious is that the exception was was "org.apache.commons.cfs.FileSystemException" - This error still persists even though I have done the following: 1.  Completely de-installed Apache and hid the PHP directory. 2.  Re-installed ColdFusion from scratch. Any direction would be greatly appreciated - this error is affecting multiple modules of a website that is used constantly by both our customers and our internal employees. Thanks Curt
