OCS 2007 users cannot communicate with LCS 2005 users
Posted on 2008-06-25
We have recently installed OCS 2007 on an additional machine to coexist with LCS 2005. We have configured the OCS server, all services are running and users can log on. The problem is when we try to send messages to user under LCS 2005 we cannot send messages.
When I view the logs I see this error:
Event ID:14428 Source: OCS Protocol Stack
TLS outgoing connection failures.
Over the past 0 minutes Office Communications Server has experienced TLS outgoing connection failures 1 time(s). The error code of the last failure is 0x80090322 (The target principal name is incorrect.) while trying to connect to the host "qcklcs01.kaisa.ramcar.com".
Cause: Wrong principal error could happen if the peer presents a certificate whose subject name does not match the peer name. Certificate root not trusted error could happen if the peer certificate was issued by remote CA that is not trusted by the local machine.
For untrusted root errors, ensure that the remote CA certificate chain is installed locally. If you have already installed the remote CA certificate chain, then try rebooting the computer.
Can someone lend me some ideas how to get trough this problem?
Thanks in advance
