Soon a Windows update will be released (August the 14th) which will block the use of RSA keys less than 1024 bits in length for any Windows computer where the update is installed. When this update is installed on Operations Manager Management Servers or Gateways that are managing HP-UX PA-RISC computers, the HP-UX computers will generate heartbeat and SSL certificate alerts, and all monitoring of the computers will be interrupted until remediation is performed.
So anyone monitoring HP-UX PA-RISC computers with SCOM R2 / OM12 should be aware of this.
The same posting of the OM12 Engineering Team contains two methods to solve this issue. Posting is to be found here.
