ICTinus presentation at Techdays Belgium 2011

June 13th, 2011 No comments

ICTinus was sponsor of the Belgian Techdays 2011; to create enough “animo”, we worked around the “Pirates of the Carribean 4” theme, where visitors of the booth could win movie tickets or even a HP sponsored SmartTouch PC.

At the Student Day, I presented ICTinus in real Jack Sparrow style…, followed by a “company movie”, presenting some of our consultants.

Check out the introduction and full movie at the following link:

Private Key Missing from Exchange SSL certificate

June 13th, 2011 No comments

Although the creation/import of Exchange SSL certificates are straightforward (check out one of my other blogposts on if you should need assistance on this) , you sometimes receive an error within the Exchange console or Powershell when manipulating SSL certificates:

Error: The certificate with thumbprint XXXXXXXXX was found but is not valid for use with Exchange Server (reason: PrivateKeyMissing)

Enable-ExchangeCertificate : The certificate with thumbprint “0000000000” was found but is not valid for use with Exchange Server
(reason: PrivateKeyMissing).
At line:1 char:29
Enable-ExchangeCertificate -Thumbprint 00000000000 -Services "IIS"

Cause: the real cause behind this error is not always that easy to determine; the most common reasons could be classified as “corrupt”, “initial CSR request was created on another Exchange Server” or “CSR was not created by Exchange Server at all”.


To resolve this issue during SSL certificate installation in Exchange 2007 or 2010 server, use the following procedure:
Method 1: Repair Damaged Certificate (Windows Server 2003/2008)
1. Start / Run / MMC / add the Certificate Snap-In for the Local Computer account.
2. Double-Click on the recently imported certificate.
3. Select the Details tab.
4. Click on the Serial Number field and copy that string.
Note: You may use CTRL+C, but not right-click and copy.
5. Open up a command prompt session. (cmd.exe aka DOS Prompt).
6. Type: certutil -repairstore my "SerialNumber" (which was copied in the previous step.).
7. After running the above command, go back to the MMC and Right-Click Certificates and select Refresh (or hit F5 in the MMC).
8. Double-Click on the problem certificate. At the bottom of this window (General tab) it should state: "You have a private key that corresponds to this certificate."

It should know be possible to enable the Exchange certificate for IIS or other services (Enable-ExchangeCertificate…)

Cheers, Peter
