I do think that you also changed the document tab to have cachemgr.cgi in it? Maybe that's the difference? I had to enable a default content page and set cachemgr.cgi there. You didn't have to? I added the cachemgr.cgi to the web service extension list. Instead of allowing the "all unknown CGI extensions" I added cachemgr.cgi. I also tried with cachemgr.exe (renamed the file) because the wizard also talks about CGI EXE scripts. This didn't help either. Our servers are running w2k3 with the latest hotfixes, just not SP1. I've found a Microsoft KB Article about it: 145661: http://support.microsoft.com/default.aspx?scid=kb;en-us;145661 There I notice that after " The specified CGI application misbehaved by not returning a complete set of HTTP headers.", they have "The headers it did return are:" but I don't have that last part. Best regards, Jeroen.
