Put the Bugzilla files in a directory that is named something <EM >other</EM > than what you want your end-users accessing. That is, if you want your users to access your Bugzilla installation through <SPAN CLASS="QUOTE" >"http://<yourdomainname>/Bugzilla"</SPAN >, then do <EM >not</EM > put your Bugzilla files in a directory named <SPAN CLASS="QUOTE" >"Bugzilla"</SPAN >. Instead, place them in a different location, and then use the IIS Administration tool to create a Virtual Directory named "Bugzilla" that acts as an alias for the actual location of the files. When creating that virtual directory, make sure you add the <SPAN CLASS="QUOTE" >"Execute (such as ISAPI applications or CGI)"</SPAN > access permission. </P ><P > You will also need to tell IIS how to handle Bugzilla's .cgi files. Using the IIS Administration tool again, open up the properties for the new virtual directory and select the Configuration option to access the Script Mappings.

On the Documents tab page of the virtual directory properties, you need to add index.cgi as a default document type. If you wish, you may remove the other default document types for this particular virtual directory, since Bugzilla doesn't use any of them. </P ><P > Also, and this can't be stressed enough, make sure that files such as <TT CLASS="filename" >localconfig</TT > and your <TT CLASS="filename" >data</TT > directory are secured as described in <A HREF="security-webserver.html#security-webserver-access" >Section 4.2.1</A >. </P ></DIV ></DIV ><DIV CLASS="section" ><H2 CLASS="section" ><A NAME="install-config-bugzilla" >2.2.5.
