terrum 1 Posted October 9, 2015 Share Posted October 9, 2015 I've upgraded ERA Server (VA) to the latest version 6.2.11.1. All internal server components are up-to-date. Next, I went ahead with upgrading ERA Agent on Clients to the latest version (6.2.171.0 -> 6.2.190.0) and I used a GPO method as described here to deploy the new Agent. Everything works great on the Client side - the new Agent gets installed after reboot, however, in ERA Server I'm getting a duplicated record created for each Client that was upgraded. The new record appears in the "Lost And Found" folder even though there is already existing record with exactly same name, same MAC, same everything just in a different folder!! The old record becomes orphaned. I have to delete the old record and manually move the new record from "Lost And Found" to the correct folder to get things back to normal. I'm curious if anybody else noticed the same. Any ideas why this is happening and how to prevent it? Perhaps a setting in ERA Server or something else that can help to avoid the duplicates? Thanks!

Mike 8 Posted October 12, 2015 Share Posted October 12, 2015 My guess is that it happened because the agent is designed to be upgraded using the Remote Administration upgrade task (it is called something like that), and because it was a fresh install (even though it was installed on top of the old agent), it has been detected as a fresh computer. I can't find the instructions for updating right now, but if you hunt around the knowledgebase you should find what you are looking for. You basically run an upgrade on the Remote Administration as though you are going to upgrade the ERA server itself , but you select all the computers you want to get the new agent deployed to, and it upgrades each machine in the list to the latest agent. Good luck Mike Link to comment Share on other sites More sharing options...
Administrators Marcos 5,069 Posted October 12, 2015 Administrators Share Posted October 12, 2015 As already mentioned by Mike, to upgrade agent on clients, send an ERA Component Upgrade task to them to upgrade agent automatically. Link to comment Share on other sites More sharing options...
terrum 1 Posted October 13, 2015 Author Share Posted October 13, 2015 Thank you, I guess that was the cause. I think it wouldn't harm to add a mechanism in ERA Server which would recognize Agent upgrades even when a method other than ERA Component Upgrade task was used. This is really a basic feature many will benefit from. At least make it available so that one can use it when required to avoid the duplicates. Thanks.

dlaporte 14 Posted October 21, 2015 Share Posted October 21, 2015 I agree with terrum I use GPO's for agent and Endpoint. Works like a champ..except for the duplicates that get created in Lost and Found.. They also show up with IP addy and not HOSTNAME Link to comment Share on other sites More sharing options...
ESET Moderators TomasP 316 Posted October 23, 2015 ESET Moderators Share Posted October 23, 2015 Hello, GPO can be used for the initial deployment. However, once the Agent is present, it is recommended to upgrade it using the built-in mechanism. Link to comment Share on other sites More sharing options...
dlaporte 14 Posted October 23, 2015 Share Posted October 23, 2015 that's doubling the work? Lame.. Link to comment Share on other sites More sharing options...
ESET Moderators TomasP 316 Posted October 26, 2015 ESET Moderators Share Posted October 26, 2015 It is not doubling the work, it actually saves time. You do not need to prepare anything, you just run a task from ERA webconsole and ERA takes care of delivering the task, downloading the correct version, installing it, etc. Link to comment Share on other sites More sharing options...
pengu1n 1 Posted March 22, 2016 Share Posted March 22, 2016 Hello. We have about 600 workstations in our network and about 20 OU in AD structure for PCs. So now i synchronized AD tree into ERA and can see all workstations. But when we deploying ERA agents by GPO all computers are duplicated into Lost&found. Is there a way to automatically make order by AD structure in ERA console? Link to comment Share on other sites More sharing options...
ESET Staff MichalJ 434 Posted March 22, 2016 ESET Staff Share Posted March 22, 2016 Hello Penguin. Issue you are talking about occurs in case, when ERA server has issues with DNS name resolving of the computers. What you can do, is to run the "computer rename task" targeted on lost & found group, and then re-sync with Ad, with collision handling set to "move". You have to make sure, that the lost & found name is the same, as the one resulted from AD sync. Link to comment Share on other sites More sharing options...

jj41 0 Posted May 23, 2016 Share Posted May 23, 2016 I'm having an issue getting the move function to work. I have my AD sync set to move pc's with the same name out of lost and found and into the correct OU, however when it ever runs with it on I get the message "RemoveComputer: Specified computer was not found". If I set collision to skip instead of move then the sync runs just fine. I don't know why I'm getting this message. Link to comment Share on other sites More sharing options...

We had a bug where de-duplication ended with this specific error and only solution was to manually remove problematic duplicates. This issue was fixed in 6.3 release.

jj41 0 Posted May 24, 2016 Share Posted May 24, 2016 I am on 6.2 for the server and the web console. I wasn't part of the installation process so I don't know if upgrading is free. If it is free how do I go about upgrading to 6.3? Link to comment Share on other sites More sharing options...

Please follow documentation for Remote Administrator Components Upgrade task. In case is is not possible to use this task (it requires access ESET repository servers for installers to be downloaded), you may proceed with manual upgrade - in your case upgrade of SERVER and Webconsole is required, as their version must match.

jj41 0 Posted May 24, 2016 Share Posted May 24, 2016 I backed up all of the certificates, my only other question is when I upgrade will it wipe out all of the custom settings I set up? Link to comment Share on other sites More sharing options...

Not sure what you meant by settings, but it should not remove anything you created in Webconsole. I would suggest you to backup database if possible before upgrading, as there wont be way back once database is upgraded to newer version. Link to comment Share on other sites More sharing options...
