Apache Alias in Internet Explorer

I'm using Vs.php 2.4 (2,4,4,4494).
My source code exists on a linux server so I've mapped a drive (T) to \\sourceserver\htdocs$. My source exists under a folder called mysource. There are some additional folders that I need located in phpincludes and phpincludes/shared_source. I need them accessable because they contain javascript that my main app requires.

On the linux server we have Apache running and in it's httpd.conf file we have

Alias /shared_source/ "/usr/local/apache/htdocs/phpincludes/shared_source/"
Alias /phpincludes/ "/usr/local/apache/htdocs/phpincludes/"

This works great on the Linux server but when I use Vs.php I can't seem to get it to work.
I've modified the httpd-template.conf file so it says:

LoadModule alias_module "$$APACHEDIR$$/modules/mod_alias.so"
...
...
Alias /phpincludes/ "//sourceserver/htdocs$/phpincludes"
Alias /shared_source/ "//sourceserver/htdocs$/phpincludes/shared_source"

It appears to work fine when I locally debug in using Firefox as my browser, however it fails in I.E. Does anyone have any thoughts? I understand that this may not be directly related to Vs.php but I'm hoping that some one here has some suggestions.

Thanks
