Default Authentication Settings Exchange 2007 IIS Application & Virtual Directories
Posted by shauncroucher on November 9, 2009
You can find these settings in IIS7. Select each Virtual Directory and then IIS section –> Authentication. Listed are the VD’s that are enabled by default with a vanilla install of Exchange 2007.
Note these settings are from Exchange 2007 Standard SP2 Installation, but should be the correct settings for all versions of Exchange*.

SSL Settings:
All the Virtual directories are set to Require SSL with 128bit except for OAB that DOES NOT require SSL and RpcWithCert which DOES NOT require 128bit (it DOES require SSL though).
* Unchecked on SBS 2008 at this time.
