Unable to connect at OCS 2007 R2 Live Meeting RRS feed

  • Question

  • I have installed and configured the OCS 2007 R2. IM and file transfer, or even Application Sharing are working fine.

    however when I tried to start the Live Meeting, it prompts for an error. I also noticed that there is error in the server side. We have deployed a load-balancer in front of the Frontend server. ocsfe23 and ocsfe24 are the hostname, while OCPOOL is the pool name

  • Hi,

    This error is sometimes associated with a mismatch between the certificates. Check your cert validation to be sure of this. I did come across this post which can be the same error that you are experiencing : Have a look at this link: http://support.microsoft.com/kb/968100/en-us
