I am unable to call a webservice from an ASP.NET page using SSL.  If I 

call the wsdl file from Internet Explorer 6 I can make a secure connection 

to the webservice and invoke the methods without any problem.



However,  If I add the web reference to an ASP.NET project (making sure to 

specify https when I add the reference) I get the following error when I 

call the webservcice:



The underlying connection was closed: Could not establish trust 

relationship with remote server. 



So what is IE 6 doing that allows it to connect to the webservice that 

ASP.NET doesn't do.  Is there some function I need to call or property I 

need to set?



I found an example that used WebRequest and tried that.  I still got the 

same error.  The documentation stated that WebRequest will automatically 

use SSL when used with https.



I also looked on GOOGLE, it looks like other people are also having this 

problem.  I tried some of the suggestions that I found there but they did 

not resolve the problem.



Any suggestions, samples or white papers on this subject would be greatly 

appreciated.
