CF10 expandPath() problem

I currently have 2 servers.  Server 1 runs Win 2003 with CF9 and IIS.  Server 2 runs Win 2008 R2 64bit with CF10 and Apache 2.2 with virtual hosts.

For years, on Server 1 when it ran CF7, CF8, and now CF9, if I were to run 'expandPath' this is the behavior I would see:

expandPath("/")  -  web site root directory  (D:\sites\mysite\htdocs\)

expandPath("/myDir/")  -  directory under web site root (D:\sites\mysite\htdocs\myDir\)

expandPath("/../storage/")  -  directory above web site root  (D:\sites\mysite\storage\)

But, now on my Server 2, the behavior has changed to:

expandPath("/")  -  web site root directory  (D:\sites\mysite\htdocs\)

expandPath("/myDir/")  -  directory under web site root (D:\sites\mysite\htdocs\myDir\)

expandPath("/../storage/")  -  directory above web site root  (C:\ColdFusion10\cffusion2\bin\)

I can't figure out if this is an issue in my configuration/setup or if this is a CF10 bug.  Any help would be greatly appreciated.

Thanks,

Daniel

I have been able to confirm that this works without issue under Server 2008 R2, IIS7 and CF10.  I'm guessing I have a configuration off somewhere, but I have no idea where to look.
