i built a new CA into my domain. I can provide User and Webserver-Certificates, and they work. But now i try to create a new certificate for my Exchange 2010. I created a new request whith the wizard in Exchange2010 and transfered the txt-file to the DC where the CA is located. When i open the CA, i can see all my recently issued certificates. But now, I try to submit a new request, whith the created txt-file attached, and ... nothing happens. There is no error, no dialog and no error into the event-log, - nothing happens. I canot see any changes into the CA-Folders, no pending request ... nothing.
Can you tell me, how i can create the nessecery .cer file to complete the pending request on exchange 2010?
