Secure Certificate add in IIS 7 disappears from Certificates list

Hi,

Does IIS 7 have a problem with 4096 bit length for a secure certificate?  I got one and am trying to install it and it shows up in the Server Certificates window, until I click on something else (such as Sites) and then go back into the Server Secure Certificates area.  It is then gone.

This is happening repeatedly.  

?

Thanks!

are you getting any specific error in event logs? Make sure that when you install certificate, it should be applied. If possbile please share the screen shot.

There were no entries in the log associated with IIS or certs, etc.

it happens when SSL certificate that doesn't contain both the public and the private key causes the issue to disappear the certificate from the IIS. Make sure the certificate was installed properly.
