Whe had a server running IIS W2K Server with a certificate for SSL and
everythin was fine.

Now whe have a new webserver and i want to move the certificate to the new
server. The export and inport works fine, but after that when i try to acces
the server via ssl i get the following error :
cannot find page

In the event viewer is the following error :

The server certificate for instance '1' does not chain up to a trusted root

the root CA's are all ok.

anybody an idee

Excuse me for the bad english
