So we noticed the other day that remote control stopped working for all systems. Browsing through threads, I found that the issue may be a result of an expired ssl certificate. So I check the certs on our W2K3 server and sure enough, the zcmSignedSSL.cer had expired on March 4th. Then it all came back, March 4th was the day I did the install. I followed this doc to create the certs:

So now the question is, how do I renew this cert? And is there a way to renew for more then an year?
