Office Communication Edge Server 2007

[SAM8907]

I recently deployed OCS 2007 standard edition and an Access edge server. The internal communication have no problem but the communication between the OCS server and Access edge server has a certificate error message even though the certificates where issued by the same issuer. here is the error that I,m getting:

Routing trust check and MTLS connectivity: Received a failure SIP response
Routing trust check and MTLS connectivity: MTLS connection establishment succeeded but received a SIP
failure response. This usually indicates lack of routing trust between the remote
server and the current machine. Check the local and remote server certificates for any
misconfiguration. In addition, check whether the local server is recognized
as a trusted server by the remote server.


Any help?

Thanks very much
