During an attempt to activate the Cisco CallManager Service (ccm.exe) on the Cisco CallManager server, the "Error 1542, Exception in installing service. CDBLException Dump: [COM error] Com error description =[][]" error message appears


Core Issue

The issue is mostly caused by Domain Name System (DNS) issues in the Cisco CallManager Cluster.


In order to resolve the issue, make sure the hosts and lmhosts files are properly updated with the Cisco CallManager hostname and IP address information.

omplete these steps in order to resolve the issue:

  1. Ensure that the C:\winnt\system32\drivers\etc\hosts hosts file on the Publisher contains entries for both itself, the Publisher server, and the Subscriber server.

    Also, the hosts file in the Subscriber server must contain the same file. If not, edit the hosts file on both the Publisher and the Subscriber server and use the procedure mentioned in the Edit the Hosts File section of Configuring The IP Hosts File on a Windows 2000 CallManager Server.

  2. Issue these commands from the DOS prompt on both the Publisher and the Subscriber server:   
    •       IPCONFIG /flushdns   
    •        NBTSTAT -R


      Note: The upper case letter R is required.

  3.    Choose Start > Programs > Administrative Tools > Component Services. Expand Component Services > Computers > My Computer > COM+ Applications. Right-click DBL, and choose shutdown. Right-click DBL, and choose start.

  4.    Open a DOS window and type iisreset. Then, make sure the Internet Information Services (IIS) admin and World Wide Web (WWW) services are in the started state.
