The communications between Pub and Sub we broken

[jjia]

Hi,

Two MCS7825 installed Callmanager 4.0(2a). However the publisher callmanager experienced NIC problem which results the communications between Publisher and subscriber callmanager was down. And there is DCOM error message says it can not communicate with subscriber. See the attached event view information

Any ideas?

When ethernet port of a call manager gets disconnected and a large series of DCOM errors are seen in the event log, the resolution is to either add entries in lmhosts for machine name or reboot CCM.
