Hi,
I need to renew the SSL certificates on my 3 CAS servers. I renewed the the first one and tried to export the certificate from first one and import to other two CAS server. I could neither import nor delete the old certificate. For deleting the certificate it says:
" A special Rpc error occurs on server NPL-CAS2: The internal transport certificate cannot be removed because that would cause the Microsoft Exchange Transport service to stop. To replace the internal transport certificate, create a new certificate. The new certificate will automatically become the internal transport certificate. You can then remove the existing certificate"
and for importing the certificate it says:
"A special Rpc error occurs on server NPL-CAS2: Cannot import certificate. A certificate with the thumbprint CA3FTC4EW42DC4AA844A132D1E268360944716E0 already exists."
How can I solve the problem ?
