I cannot Process the Pending Request in IIS

Customer Support > SSL Certificates > IIS 5 & 6 > FAQ

This is usually beacuse there was a problem when creating the CSR (Certificate signing request). However, it can be because of the following:

  1. The certificate was not in the correct format.

  2. There might be spaces in the certificate, or before or after the certificate when installing into the server.
  3. The headers and footers were not included (----BEGIN CERTIFICATE----- and ----END CERTIFICATE----- )
  4. The pending request was deleted and new csr generated. A pending request represents an unique private key. If the original pending request for the certificate request was delete, the certificate can’t be installed.
  5. Permission to the private key (in the certificate enrollment request folder in the mmc, not the certreq.txt file) was lost.
