I'm not trying to stir the pot so-to-speak; I'm just trying to figure out why nothing's happening with what many see as an important issue with the SQL Server driver for Drupal 7. This driver is maintained by the Commerce Guys.

There has been a major issue with the update from Drupal 7.12 to 7.14 and 7.15 for several months that was noted on these two reported issues:

Hello all
I am trying to install drupal on my shared hosting plan. I have already successfully installed drupal 7.14 on my desktop windows server 2008 with IIS7. I plan to recreate the same site on the 3rd party webhost.
The hosting plan has the following:
1. Windows server 2008
2. IIS6
3. PHP 5.2.5
4. MySQL 5.0.91

I have setup my core drupal install at a subdomain http://dessites.des-us.com. It was working quite correctly, until suddenly, I get this error on browsing to the site:
Fatal error: Class 'PDO' not found in ........includes\database\database.inc on line 184

Drupal 7 / MS SQLSRV / IIS 7.5 (on localhost)

I'm trying to create a multisite setup on my localhost account with Drupal 7, and it's not been as easy as I had hoped. The biggest issue is that all of the tutorials on setting it up are for Apache and/or hosted setups.

This is what I need:

http://localhost (main install)
http://localhost/site1
http://localhost/site2
http://localhost/site3

Does anyone either know of a great tutorial or documentation on how to do this? If not, some basic steps on accomplishing this would be great. Thanks for any help.
