I'm having some problems with the web interface of 1.8e installation on Windows 2003. It works to a point. When I attempt to change the settings of a list member (such as adding noprobe/renew, I get the error "CGI ERROR The specified CGI application misbehaved by not returning a complete set of HTTP headers. In the IIS logs that attempt is logged with a 502.2 which just means error in cgi application. The thing that is driving me nuts is that it only fails 9 times out of 10 attempts. I have set the permissions on the 5 files in windows\system32 mentioned in the manual and the faq. I have set up cgi-bin in its own applicatin pool Does anyone have any suggestions of other things to check.
