PCI compliance scan is failing because of this, I'm aware of adjustements that need to be made for 2003, but this is on a SBS 2008. Anybody have any ideas for a fix? RWW must be enable, users need it so that is not an option.

Susan Bradley "SBS DIVA" has posted a number of blog entries for PCI Compliance on SBS 2008 and 2003  found here http://msmvps.com/blogs/bradley/search.aspx?q=PCI+Compliance&o=Relevance

The key is usually disabling SSL 2.0

The reality is that the SBS server shouldn't be hosting websites for ecommerce or processing online credit card transactions

The server isn't processing any cards or payments but because we have a network and server we are required to pass PCI compliance.  Its a scam put in place by credit card company's but there's no choice, it must be done.

I run sbs 2003. To fix the problem i performed the following.

Set the UseHostName property
To set the UseHostName property, follow these steps:

   1. Click Start, click Run, type cmd, and then click OK to open a command prompt.
   2. Change to the folder where the Adsutil.vbs tool is located. By default, this folder is the following:
      %SYSTEMROOT%\Inetpub\AdminScripts
   3. Type the following command, where x is your site identifier:
      cscript adsutil.vbs set w3svc/x/UseHostName true

The solution did not work for us but this is the correct solution to the problem.  We have fixed our problem on our end but it required a bit more in depth configuration.
