How to generate CSR for installing SSL certificate in IIS 7 ?

Recently, one of our customers approached us with the request to install an SSL Certificate in the IIS 7 Windows 2008 server.

3. Then, from the Actions pane on the top right, we select Create Certificate Request. Now the Distinguished Name Properties dialog box opens.

4. There, we fill in all the details and click OK.

Common errors encountered when performing SSL certificate in IIS 7 ?

Here, you will see how to fix a few errors we may come across during these processes.


i. Cannot find the certificate request associated with this certificate file.

This error occurs when we try to install a certificate using Microsoft Internet Information Services (IIS) 7.0 Manager.

We may come across either of these messages:


Error message 1:

Cannot find the certificate request associated with this certificate file. A certificate request must be completed on the computer where it was created.


Error message 2:

There was an error while performing this operation
Details: CertEnroll::CX509Enrollment::p_InstallResponse: ASN1 bad tag value met.
0x8009310b (ASN:276)

The certificate is installed correctly despite the error message.

This issue occurs because the IIS Manager performs a lookup operation to look for a friendly name of the certificate during the installation.

However, the code that performs this lookup operation misses this specific case, and it does not know how to retrieve the friendly name of a certificate in a PKCS#7 file. That is why the lookup operation fails, and we receive the error message.


To resolve this problem, add a friendly name to the certificate:

1. Select Start >> Run, certmgr.mmc >> OK.

2. Select File >> Add/Remove Span-ins >> Certificates >> Add >> OK.

3. Then select Computer account >> Next >> Finish >> OK.

4. Expand Certificates (Local Computer), and Personal, and then Certificates.

5. Right-click the certificate, and then select Properties.

6. Edit the Friendly name field.


ii. The request or private key cannot be found

While installing an SSL certificate using IIS 7.0, we may also receive the error:

The request or private key cannot be found . The request or private key cannot be found
An incorrect certificate or server mismatch can cause this error.

In such a case, make sure we use the correct certificate and that we are installing it to the same server that we generated the CSR on.

However, if we are sure of those two things, we may just need to create a new Certificate Request and reissue/replace the certificate.
