IIS 5 .printer ISAPI filter applied

Remote Web server supports Internet Printing Protocol Description : IIS 5 has support for the Internet Printing Protocol(IPP), which is enabled in a default install. The protocol is implemented in IIS5 as an ISAPI extension. At least one security problem (a buffer overflow) has been found with that extension in the past, so we recommend you disable it if you do not use this functionality.
To unmap the .printer extension: 1.Open Internet Services Manager. 2.Right-click the Web server choose Properties from the context menu. 3.Master Properties 4.Select WWW Service -> Edit -> HomeDirectory -> Configuration and remove the reference to .printer from the list.
