IIS 6.0 retuning private IP in HTTP reponse header

Recently got audited and a scan found that one of my IIS 6.0 servers was returning it's private IP in the HTTP response body.  How can I block this IP from being displayed?

attached is the actual snippet from the audit.

I believe that if you place a host header into your configuration, it will reply with the host header rather than the IP address.  Purely a guess.

Best of luck,

Worked with Microsoft support on this.  They told me the easiest way to do this was remove the reference to the default pages in the website properties.  I removed them then disabled the use of default pages.  Thanks for your assistance.
