ShaneDT 13 Posted May 28, 2016 Share Posted May 28, 2016 The scenario. Multiple remote notebooks that rarely visit the office. Eset agent configured to report back to the ERA server via the office Internet IP address. Customer changes ISP without telling IT Support... Eset agent on remote notebooks no longer reporting back to ERA server... Can I simply create a new EraAgentInstaller with the new ISP Internet IP as the host server address, email this out and have the users run this on their notebooks? If yes can I just modify the following line in the existing EraAgentInstaller.bat file? set server_hostname= Thanks Link to comment Share on other sites More sharing options...
Administrators Marcos 5,070 Posted May 28, 2016 Administrators Share Posted May 28, 2016 If the ERA server was not reinstalled, you can change the server name in the Agent Live installer batch file and re-deploy it on clients. If ERAS has been reinstalled, create a new Agent Live installer from the console so that it contains both the correct server name as well as certificates that are currently being used.

ShaneDT 13 Posted May 28, 2016 Author Share Posted May 28, 2016 (edited) Thanks Marcos, there has been no change on the ERA server itself, just wasn't sure if you could re run the EraAgentInstaller.bat on a computer that already has the agent installed. Will run it and report back how I go Edited May 28, 2016 by ShaneDT Link to comment Share on other sites More sharing options...
ShaneDT 13 Posted May 28, 2016 Author Share Posted May 28, 2016 Didn't work. Ran the modified EraAgentInstaller.bat. Status Log still reporting replication failure to the old IP address. Restarted the computer to restart all services. Status Log still reporting replication failure to the old IP address. Now testing an uninstall of the agent and then reinstall using the modified bat file. Hopefully this should work. Where does the agent store this server_hostname value? I couldn't find it in the registry so assume it must be in a configuration file? Link to comment Share on other sites More sharing options...
ShaneDT 13 Posted May 28, 2016 Author Share Posted May 28, 2016 Uninstall / reinstall worked. This created a new object in the Lost & Found static group. Running Static Group Sync moved it back to the correct static group re Group Policy. The old object for this computer hasn't been removed though (or merged), so I've had to manually deleted the old object. Link to comment Share on other sites More sharing options...
ESET Staff MichalJ 434 Posted May 28, 2016 ESET Staff Share Posted May 28, 2016 The most probable reason why it didnt work was that installed version of ERA agent was older, than the currently available one. So running the live installer will perform "upgrade" (install new version over old one), but keep the settings. If you run it again, it will perform "repair", meaning change the config with the new parameters. So in such cases, you shoul reinstall it twice, to achieve the desired state.

ShaneDT 13 Posted May 28, 2016 Author Share Posted May 28, 2016 Hi Michael, I don't think that was the case. The .bat file appears to call a specific version of the agent, in this case 6.3.136.0. So it should have been the same version as it was the same bat file, only the server_hostname parameter was changed. And to verify I just checked the details of the duplicate entries in ERA Server, they are both reporting installed agent as 6.3.136.0 (I haven't deleted the duplicate yet, was waiting to see if it might clean itself up). So the uninstalled and reinstalled agent version is the same. Link to comment Share on other sites More sharing options...

So the uninstalled and reinstalled agent version is the same. Any chance you have trace.log before you uninstalled AGENT? After repair with new hostname, AGENT should be trying to connect to this hostname, and if it fails, it will attempt to connect to last hostname that worked in history (this is fallback in case configuration is accidental broken). Therefore you have seen failed connection attempts to old address in status log. Unfortunately previous error (in this case most relevant) was not visible.
