In some cases you may need to change MMSCurrentMachineID and InstanceID on agent machine, e.g. when there are issues with agent registration.
This article explains how to do this.
Remove the Agent from Management Server and run a special script that will clear the local databases to avoid duplicates. After you re-add the machine to Management Server, Agent will obtain the new configuration data from it automatically.
Perform the following steps on the Agent where you want to change MMSCurrentMachineID and InstanceID:
- Delete the agent from Management Server: go to Settings > Agents, select the agent and click Delete on the menu on the right
- Generate a new GUIDs for MMSCurrentMachineID and a new GUID for InstanceID and note them, as they will be required for running the script:
- On Windows: use New-Guid cmdlet (launch Command Prompt -> type powershell to open powershell interface -> type new-guid to generate a GUID)
- On Linux: open Terminal and run the following command: uuidgen
GUID can be generated on any machine, not necessarily on the machine where you plan to change IDs.
