Re: Callmanager Subscriber crashed lost certificate
So, you can see if you can recover the default certificate or just install a new certificate. The simplest way to do this is to configure a standalone root CA in Windows. The information you need to know about the cert is when you install/upgrade Cisco CallManager, the SSL self-signed certificate, httpscert.cer, automatically installs on the IIS default website that hosts the Cisco CallManager virtual directories, which include CCMAdmin, CCMService, CCMUser, AST, BAT, RTMTReports, CCMTraceAnalysis, PktCap, ART, and CCMServiceTraceCollectionTool. The SSL certificate gets stored in the C:\Program Files\Cisco\Certificates directory. If you prefer to do so, you can install a server authentication certificate from a certificate authority and use it instead of the SSL self-signed certificate. To use the certificate authority certificate after the Cisco CallManager installation/upgrade, you must delete the self-signed certificate, as described in the Cisco CallManager Security Guide. Then, you install the server authentication certificate that is provided by the certificate authority, as described in the certificate authority documentation.
Windows, well TechNet, has more than ample info on setup of a standalone root CA unless you decide to go with a 3rd-party like Verisign. You may be able to recover the original certificate from the Subscriber. I'd see if the file is still there and then check the IIS settings to see if it needs to just be reassociated with the Default Web Site.
