MOMCertImport.exe Catastrophic Failure

July 30, 2026

1 min read

I ran into this one while setting up a SCOM 2012 R2 Gateway server. When importing the .pfx using MOMCertImport.exe I received the following error:

The certificate is valid, but importing it to certificate store failed.

Error description: Catastrophic failure

Error code:8000FFFF

ImportPFXCertificate failed: Catastrophic failure

Error code: 8000FFFF

Turns out, this was a result of leaving the “Include all certificates in the certification path if possible” box checked when performing the certificate export. After re-exporting and unchecking that box, I was able to import the certificate without issue.
