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.
