The certificate signing operation failed in SCOM 2007 R2

While working with SCOM 2007 R2 and trying to monitor a Unix and Linux server, running the Discovery Wizard I ran into this problem. In another location, it said “The certificate for this system is not valid”. This prevented me from adding this server to the console even after I’ve manually installed the agents on those computers.

Here’s a good tool for people like me who aren’t good at navigating around a Unix system or Linux system. What you need to do after you’ve downloaded, installed and ran it, you need to browse to the location where the certificate is located as below:-


Copy the scx-host-<hostname>.pem file to anywhere in your SCOM server. Simply run this command at the path where you copied the .pem file to. It will simply sign the file and create a new file called scx_new.pem.

scxcertconfig -sign scx-host-<hostname>.pem scx_new.pem



Copy the new file back to the original location of /etc/opt/microsoft/scx/ssl replacing the original file. After which you would have to restart the service with the command below:-

scxadmin –restart


Now that should do the trick. Go ahead and try to run the Discovery Wizard again and see your Unix and Linux computers being monitored.
