Hi ,you can try these :
a -) on the core restart the LAndesk Management gateway service
b -) Check that at least 1 file with a .0 extension is present and identical both on the core server and the clients:
- Core: [drive]:\Program Files\LANDesk\ManagementSuite\SharedFiles\Keys
- Client: C:\Program Files\LANDesk\Shared Files\cbaroot\certs
You can check it with MD5summer
c -) Change the agent configuration to use the core server name, not the cname dns host name
Thanks. Option C is what was causing My Windows clients to not communicate with the core.
I have had the same issue in a test environment. Glad to understand that helps.
