Whenever I run the webserver example with certificates generated using makecert from .net I have problems with the webserver responding to requests. Here is the console output of the webserver example:

This test class implements a small HTTP server that supports HTTP and HTTPS. It
always returns the same static page.

Please enter the IP address of the network adapter to listen on [use 0.0.0.0 to
listen on all installed network adapters]:
0.0.0.0
Please enter the port to listen on [or 0 to automatically select one]:
30009
Please enter the security protocol you wish to use for incoming connections:
[1] None
[2] SSL3
[3] TLS1
[4] SSL3 and TLS1
2
How do you want to load the certificate?
1 = from certificate store
2 = from PFX/P12 file
3 = from .cer file
3
Enter the full path of the certificate file:
c:\mycert.cer
The certificate is not associated with a private key. Please enter the path to a
PVK file you want to associate it with:
c:\mycert.pvk
Using the following certificate:

Firefox finally asked me (didn't make any changes) to accept the certificate, and after that it just told me that the connection terminated unexpectedly.
Here is the console output of the webserver:

I found a similar post http://www.mentalis.org/forum/thread.qpx/107
but putting -sky signature isnt fixing it yet!

I got it to work using different params on makecert
C:\Program Files\Microsoft Visual Studio .NET 2003\Common7\Tools\Bin>makecert -sk "ssldemo" -pe -r -e "12/01/2004" -sky Exchange -sy 12 -sp "Microsoft RSA SChannel Cryptographic Provider" -n "CN=localhost,OU=foounit,O=foodev" -ss MY -eku 1.3.6.1.5.5.7.3.1,1.3.6.1.5.5.7.3.2
