I'm running IIS7 (Vista x86) virtual machine on Vista x64.
I want to set the server root on a physical disk outside the virtual machine but having problems.
I have created a shared folder (drive S) in the virtual machine which contains the server root.
(UAC=off on both the virtual machine and the host)

drive S is on the host machine.
To set a site root folder in IIS Manager I can browse to the shared folder "Network Drive S" which I can select but it just does not work.
Network connections are disabled on the virtual machine.

How to configure?
