PCI Scanning

Hi All

While scanning one of our internal servers, the security scanning software gave me this error:

Title: Banner Based Vulnerabilities for Microsoft IIS httpd 7.5                       
Impact: One or more vulnerabilities have been found that affect this service. Please see the relevant CVEs for more details.           
Resolution: Apply the latest vendor patches to the Microsoft IIS httpd 7.5 service running on port 443.           
Risk Factor: High/ CVSS2 Base Score: 10.0(AV:N/AC:L/Au:N/C:C/I:C/A:C)

CVE: CVE-2010-3972

Additional CVEs:      CVE-2010-2730CVE-2010-1256CVE-2010-1899CVE-2012-2531

I looked at KB2489256 but I already have it installed. What else should I be looking at?

Thanks
