No problem, here are my taken steps.
1. I opend a console via mmc and used the certificates snap-in for computer account\local computer. That happend on the server that should use the certificate.
2. I navigated to Certificates\Personal\Certificates and used the Import.
3. I browsed to the location of the Verisign Certificate and opend it.
4. I used the Option Place all certificates in the following store: Personal
5. Closed the window with Finish. After some seconds I got the message the Import was succesfull.
6. In the Certificate store i can see the newly imported certificate.
The Certification Path shows me that the certificate chain looks good. Verisign can be found in the Third-Party Root Certification. At the moment, i don't know what went wrong.
