The null.htw problem arises because of issues with Microsoft Site Server and IIS. To check your pages copy the following URLString to the browser and replace URL.com with your domain and /PAGENAME with the filepath from the Root directory to the file that you would like to check.<BR><BR>http://www.URL.com/null.htw?CiWebHitsFile=/PAGENAME.asp%20&CiRestriction=none&CiHiliteType=Fu ll<BR><BR>FOR EXAMPLE THE FOLLOWING STRING WOULD CHECK 'www.microsoft.com/default.asp'<BR><BR>http://www.microsoft.com/null.htw?CiWebHitsFile=/default.asp%20&CiRestriction=none&CiHiliteType=Ful l<BR><BR>For a fix to this problem visit http://www.microsoft.com/technet/security/bulletin/ms00-006.asp<BR><BR>PS. It must be a bit embarrasing for people to see your source code, was it well commented? :)<BR>
Have checked this and it seems to be ok. Message comes back "System cannott find the file specified". I also checked all the IIS4 security issues from the test site mentioned on 4guys, with no reported errors.
