Mismatch of Credential Manager Public Keys between the SMP Server and Symantec_CMDB database.

Step 1: Check if the Symantec management agent is properly installed and can connect with the server without any issues. Do a send inventory and check logs for any communication error. Check if the Symantec Management agent is communicating with the server using HTTPS or HTTP.

Step 2: Check if Credential Manager WCF services are working properly  -

         ~Type the following URLs into the web browser if NS and Altiris Agent are set to communicate in non-SSL mode :
http://localhost/Altiris/CredentialManager/Service/CredentialManagerRegisterWebService.svc

http://localhost/Altiris/CredentialManager/Service/CredentialManagerServicesWebService.svc

      ~Type the following URLs into web browser if NS and Altiris Agent is set to communicate in ssl mode :
https://localhost/Altiris/CredentialManager/Service/CredentialManagerRegisterWebServiceSecure.svc

https://localhost/Altiris/CredentialManager/Service/CredentialManagerServicesWebServiceSecure.svc

               On typing the URL on the browser you must see a page saying “This is a Windows© Communication Foundation service.”

 Step 3 : If  Symantec Management agent is working properly along with WCF services perform the below mentioned steps -
~Perform a full backup of the SMP Server and Symantec_CMDB database.
~Remove all rows from CMClientPublicKey.
~Delete registry key HKLM\Software\Altiris\CredentialManager
~Uninstall existing Symantec management agent and re-install it. (OPTIONAL)
~After installation wait for Altiris agent to get “computer Id”. [ Check it in Symantec Management Agent > Settings dialog ]. (OPTIONAL)
~Once you see “computer id” being present re-run CMClientInstall.exe from NSCap\Bin\x64\CredentialManager as Administrator. Check whether ServerURL,Exchange, Signature values are created under registry hive HKLM\Software\Altiris\CredentialManager\Keys\{GUID.EN_US}.
~Do a reboot of the SMP Server.
~Re-launch the browser and Symantec management console to check whether existing and new Connection profiles and credentials are working.
